Hello staff I have a question about the pin connections of the HIMAX chipset in the DTS for the board in the 'IPC-M10R800-A3568J AI Industrial Tablet PC' (AIO-3568J Board) . In the DTS only the RESET PIN is connected to the PCA9555 extender chip and the IRQ PIN is connected to the RK3568 pin "RK_PC1". The kernel reports that "himax,gpio_3v3_en" is not valid. My application turns off the backlight after 30 minutes (/sys/class/backlight/backlight/brightness == 0). After a few hours I noticed that the touchscreen stopped responding (froze) but my QT application continued to work normally (log output of the background jobs). I used a simple C program to read the device /dev/input/event2. This C test program also doesn't respond when I tap the touchscreen with my fingers. So my question is: 1) Is the HX83102-B built into the tablet? 2) How is the HIMAX chip supplied with power. 3) Is there a schematic plan for the IPC-M10R800-A3568J tablet (AIO-3568J board)? Greetings |
