The Nextion Intelligent P-Series HMI displays become more and more popular because these have much more horsepower under the hood, are available in multiple sizes from 4.
Due to the much more powerful integrated processor and the bigger memory, the Nextion firmware offers also additional components and functions. But up to now, these are not often mentioned in Nextion-related forums and groups. But this time I want to go beyond simple text and ini files like in the demo project in this article and discover together with my dear readers how database tables can be handled.
Most developers know that a character like "A" is represented inside microprocessor systems as a simple number. That's called encoding. Everything started with teletype machines which used a 5bit encoding. Later, when the first computers came up, with screens and printers, the Baudot code was extended from 5 to 7 bits, giving a character space.
Now, almost everything could be encoded without shifting and tricks they thought : Upper and lowercase letters, numbers, special characters, interpunction, mathematical signs and more control characters. That gave birth to the 8bit code page system: In whatever code page, the first half, the characters 0 to remained the same, identical to the ASCII code. When you first get your Pinebook Pro and boot it up for the first time, it'll come with Manjaro using the KDE desktop.
On first boot, it will ask for certain information such as your timezone location, keyboard layout, username, password, and hostname. Most of these should be self-explanatory. Note that the hostname it asks for should be thought of as the "codename" of your machine, and if you don't know what it's about, you can make something up use a single word, all lower case, no punctuation; e. After you're on the desktop, be sure to update it as soon as possible and reboot after updates are finished installing.
If nothing appears when you click on the Networking icon in your system tray to connect to your Wi-Fi, ensure the Wi-Fi privacy switch is not disabled. Under Pinebook Pro Software Release you will find a complete list of currently supported Operating System images that work with the Pinebook as well as other related software.
The keyboard features function Fn keys in the F-key row, which include display brightness controls, sound volume, touchpad lock, and other functionality. It has also a secondary functionality for setting the privacy switches. The keyboard firmware binary can be flashed from userspace using the provided open source utility. Documentation for the keyboard can be found in Datasheets for Components and Peripherals.
Certain characters can still be generated by means of either key combinations or key sequences. The keyboard operates on firmware independent of the operating system. It detects if one of the F10, F11 or F12 keys is pressed in combination with the Pine key for 3 seconds. Doing so disables power to the appropriate peripheral, thereby disabling it.
This has the same effect as cutting off the power to each peripheral with a physical switch. So the power state value for each peripheral cannot be overridden or accessed from the operating system. The power state setting for each peripheral is stored across reboots inside the keyboard's firmware flash memory.
This guide is very basic and should be fleshed out with better pictures. There just isn't a list of steps anywhere else yet. Step 0 : If changing from ISO keyboard to ANSI keyboard, or vice versa, be sure to have a system capable of running the firmware updater that you can access either remotely or with a USB keyboard beyond the internal keyboard, as the firmware for each is very different and keys won't work correctly.
There are 10 screws on the back that must be removed, and the back panel detached. The speakers may remain attached via glue to the case and should be carefully pried off. When this is done, taking photos of how everything looks now can help put it all back together later.
There are 3 items screwed into the keyboard frame that must be removed. There are 2 large screws for daughter board, 3 large screws and 1 small screw for mainboard, and 4 screws for battery. Be sure to not lose them. Once the battery screws are removed, it should be unplugged from the mainboard and removed. Note that there are two unconnected cables lying around, that should remain unconnected.
They are used when the battery is disconnected entirely. The speakers and microphone don't have to be detached from the mainboard, but they need to be detached from the keyboard shell.
The microphones are held in place by tape, and the speakers have sticky sides. The speakers are found obviously, but the microphones two of can be found between the battery and the hinge area. At this point, the mainboard and daughterboards should be removed. When unscrewed see Step 2 they should pull out fairly easily.
Put them aside including microphones and speakers if left attached. Step 2 didn't tell you, there are 6 more screws to remove here, 3 for each of the hinges. Unscrew these and the LCD panel will be able to be removed.
You may have to jiggle or move the hinges for this. When detached, be sure to place the LCD panel such that the display is protected.
The touchpad is glued to the keyboard shell and it's glued well. There are two places it is glued to. If you can, only the middle must be force-detached.
You will think you're going to break it. Gently apply increasing force until the glue begins to detach you will hear a crackle as it comes off , and continue very slowly until the whole thing is detached. This may take minutes due to that feeling you're going to break it. In the new keyboard shell put the touchpad back where it was, hopefully the glue will remain sufficiently attached.
If there is a glue issue, this guide unfortunately has no advice currently. The LCD panel should slot back into the keyboard frame, the same way it came out. Move any tape from the old keyboard shell to the new one. These items protect the mainboard and daughterboard, and keep various wires in their right place. Some are grey and some are black. For tape that holds the speakers, microhones, or their cables in place, do not reattach yet. Install the mainboard, the daughtboard, and their connecting ribbon cable.
Be sure to put the boards in place, 2 large flat screws for the daughterboard, 3 large flat screws and one small screw for the mainboard, before attempting to place the ribbon. Reattached the microphones and speakers to their respective areas, making sure that both are properly oriented - the speaker "out" faces up, and the microphone cables as connected must face up these are opposite directions. The LCD panel, keyboard and touchpad ribbon cables should be reattached. Make sure the flap is open, insert the ribbon into the slot a portion of the cable will disappear , and push the flap down.
The cable should not be easy to pull out. The battery should be installed with the 4 screws holding it in place, and the connector attached to the mainboard. Be sure to keep the two other cables remain unconnected. Ensure all wires and other tapes are held in place. See the links in Step 0 above. Documentation for the touchpad can be found in Datasheets for Components and Peripherals. It is the only component of the Pinebook Pro held in place with strong adhesive tape.
Here are some of its features:. If you are having trouble using 2 fingers to scroll or emulate the click of a mouse's right-button, then try these solutions:. The touchpad controller is connected to the keyboard controller. All touchpad events go through the keyboard controller and it's software, then to the keyboard controller's USB port. Note that the touchpad does have separate firmware, which has to be written through the keyboard controller. Every Pinebook Pro produced before September should have its keyboard and touchpad firmware updated.
Before updating any firmware, your Pinebook Pro should be either fully charged or, preferably, running from mains. This utility will be writing data to chips on the keyboard and touchpad, so a loss of power during any stage of the update can result in irrecoverable damage to your touchpad or keyboard.
The scripts ought to work on all OSs available for the Pinebook Pro. Some OSs may, however, require installation of relevant dependencies. The instructions below assume a Debian desktop. To install these dependencies, newer Pinebook Pro models that come with Manjaro will require a different command. You need to know which model you have prior to running the updater. Firmware update steps for both models are listed below.
In addition, you might consider using revised firmware data; this is one final step that should not require a reboot:. Before making adjustments, consider updating the firmware; reset your adjustments before updating the firmware, so that your adjustments do not interfere with new functionality. Some forum members have found that an adjustment to X-Windows will allow finer motion in the touchpad. You may experiment with different settings, but 0. The line Option "MinSpeed" "0. Another forum user built on the above settings a little, and have found these to be very good:.
FingerLow has the same value as 'FingerHigh' in one config It is believed to help reduce mouse movement as you lift your finger, but it's unknown whether synaptic works like this. You may find this config to be comfortable for daily use. TabButton allows to just tab the touchpad instead of physically pressing it down to get this click noise. The right mouse click is emulated by tapping with two fingers on the touchpad. If you feel that this is not very responsive you can try this value:.
Some users may encounter an issue with the mouse jumping when typing when using libinput driver has not been test with synaptic due to their hand hitting the touchpad which can be fixed by updating the xorg settings to disable it while typing. One can disable the touchpad while typing by setting the below option in the xorg config simliar to the previou example.
The setting can be verified by using the xinput command to first list the devices and then listing the properties for the Touchpad device. It is published for early implementors and users to provide feedback.
Any part of this spec may change before the spec reaches 1. The key words "unspecified", "undefined", and "implementation-defined" are to be interpreted as described in the rationale for the C99 standard. The Secret type. The Secret data MAY contain any other entry. Note: While the Provisioned Service referenced Secret data should contain a type entry, the type must be defined before it is projected into a workload. This allows a mapping to enrich an existing secret. Extensions and implementations MAY define additional mechanisms to consume a Provisioned Service that does not conform to the duck type.
Other than the recommended type and provider entries, there are no other reserved Secret entries. In the interests of consistency, if a Secret includes any of the following entry names, the entry value MUST meet the specified requirements:.
Secret entries that do not meet these requirements MUST use different entry names. The projected binding MUST contain a type entry with a value that identifies the abstract classification of the binding.
The projected binding data MAY contain any other entry. The contents of a binding entry may be anything representable as bytes on the file system including, but not limited to, a literal string value e. The collection of files within the directory MAY change during the lifetime of the container or between container launches.
A Service Binding describes the connection between a Provisioned Service and a workload projection. Multiple ServiceBinding s can refer to the same service. Multiple ServiceBinding s can refer to the same workload. Implementations that choose to support cross-namespace service binding SHOULD provide a security model that prevents attacks like privilege escalation and secret enumeration, as well as a deterministic way to declare target namespaces.
Extensions and implementations MAY allow additional kinds of workloads and services to be referenced.
Binding to a container is opt-in, unless. For each item in the containers list:. The value of this Secret entry MUST be configured as an environment variable on the resource represented by workload. Therefore, consumers SHOULD compare the value of the observed and current generations to know if the status reflects the current resource definition.
A Reconciler implementation for the ServiceBinding type is responsible for binding the Provisioned Service binding Secret into a workload. The Secret referred to by. If the modification of the workload resource is completed successfully, the Ready condition status MUST be set to True.
There are scenarios where an appropriate resource conforming to the Provisioned Service duck-type does not exist, but there is a Secret available for binding. This feature allows a ServiceBinding to directly reference a Secret.
When the. A workload resource mapping describes how to apply service binding transformations to a workload projection. A workload resource mapping MUST define a. The following expressions MUST be applied to each object matched by the path. If not specified, the default env expression MUST be appropriate for mapping within an actual Container object.
