Wed Oct 12, The official documentation for Raspberry Pi computers and microcontrollers. 2 Posts: 26 Joined: Tue Dec 13 `dpi_output_format=0x6f005` Now from this we can see that bits 4 till 7 are zero, hence `rgb_order` is equal to `0` and `0` is no option in the table. The display works great, I have a microcontroller bit-bash out the initialisation routine, and my config in firmware/config. I'm not interested in doing contracts for bespoke functionality - please don't ask. Your typo above will not result in any failure here as that command is too simple. I get version 5. examples here should work with DPI or VGA (Using DEN/CLK is This display is entirely driven through the GPIO ( using DPI ) and mentions that compatibility with hats and other peripherals may be an issue?
