Re: Can’t get DPI working on the CM3

GPIO are configured for DPI --> next step would be to check the I/O board. Conncet CLK/DE/VSYNC/HSYNC and one Color only and see what happens. If the Display stays White your 'magic number' and/or HMDI Settings are wrong So I hooked up CLK/DE/VSYNC/HSYNC and D0-D7 (Blue) and I still shows white scr...

Re: Can’t get DPI working on the CM3

sudo raspi-gpio get post the result here (want to check if your GPIO is configured correctly) These are the results! BANK0 (GPIO 0 to 27): GPIO 0: level=1 fsel=6 alt=2 func=PCLK GPIO 1: level=0 fsel=6 alt=2 func=DE GPIO 2: level=0 fsel=6 alt=2 func=LCD_VSYNC GPIO 3: level=0 fsel=6 alt=2 func=LCD_HS...

Re: Can’t get DPI working on the CM3

most likely your Timing is incorrect. maybe you want to try this (Change in config.txt; dtoverlay=dpi24 # Disable spi and i2c dtparam=spi=off dtparam=i2c_arm=off   # Set screen size and any overscan required overscan_left=0 overscan_right=0 overscan_top=0 overscan_bottom=0 framebuffer_width=800 fra...

Re: ATTiny85 and Arduino IDE

I think your thinking of something like this https://learn.adafruit.com/program-an-a ... figuration
Just replace the arduino board with the ATTiny85 it can also be programmed using SPI.

Can’t get DPI working on the CM3

Hi everybody! So I recently started a project around the CM3 and the official IOBoard, the goal is to drive a 24bit DPI LCD screen through the J5 header! PROBLEM The problem is that I’m getting "White Screen", which is supposed to be caused by a faulty connection but I am pretty sure I’ve hooked it ...
