Just joined the devo7c train. Flashed the 256k bootloader on to a bare development board, wired the SSD1306 display. It boots !!! Now waiting for the flash chip to arrive . . .

I got things working on the SSD1306. Code changes to the init script was required as well as a hardware pin for reset of the old on bootup. After that everything went well on the screen side.

I also ended up not being able to get out of the "Missing Modules" screen, as hitting "OK" would just reboot the board. Traced it down to somewhere in the MULTI_MOD stuff, so I disabled that for now as I don't have any rf_modules to hookup. I assume, it really doesn't like the fact that no modules are present.

So now it boots up (without the reboots), displays on the SSD1306 OLED screen and we can play around in the menus.

Connections for screen as follows:

SSD1306 -> MCU Port.IO#
CLK -> A.5
MOSI -> A.7
RESET -> B.1
D/C -> C.5
CS -> B.0

The file is attached here (I named it devo7c as in devo7custom) and it WILL ONLY work for a SSD1306 screen currently. It's based on the latest nightly.

Nice !!
Thanks for sharing, do you think we need a separate build? Or could we use u7e build and add in hardware.ini a selector for the display driver?

BTW that O-led definitively doesn't look bad at all !
Are there no such small boards, with 256 or 512k which can run full featured U7E code directly ?

Maybe someday I'll build a deviation car, steering wheel transmitter with it...........

Not using the STM32F1 µcu. The ones in the 48-pin package used on those boards only go up to 128K. There are some STM32F3 CPUs that would work, but I don't see any boards in that size range. Next best bet from an µcu perspective is the STM32L4, which is the high end of the low power consumption STM32 µcus. Just checking the family diagram, it should have enough horsepower. There's exactly one board based on those: www.arrow.com/en/products/nucleo-l432kc/stmicroelectronics

That board is almost exactly the same size (15mm wide hole-center to hole center, 50mm long) as the pill boards. That board is not a Chinese clone, but from the original manufacturer, so it's a bit steep compared to the pill boards. Arrow has the best price I've found for the STM boards, as well as great shipping.

Edit: I'm already working on a deviaiton Tank.B)

Do not ask me questions via PM. Ask in the forums, where I'll answer if I can.

My remotely piloted vehicle ("drone") is a yacht.

Any updates here on this O-led stuff?

I find this small board it uses the U7E CPU:

What is your specific question? All these small OLEDs based on SH1106, SSD1306, SSD1309 - 0.96", 1.54", 2.42" 128x64 SPI - they work OK with modified initialization sequence. I have one which works for SSD1306 with charge pump and for SSD1309. SH1106 is quite similar, but I don't have one so can't promise.

It is because their memory layout and addressing mode are the same with LCD used in Devo 7. After you initialized them they just work as if they're this LCD. The only difference is contrast/brightness control - they also use commands specific to OLED controller.

Hi...i have a Sky9x board in a 9x and was happy with it until Deviation. If Deviation had a board I wouldn't hesitate to get one. If it would help I would ship the tx anywhere for someone to poke around at.

Customised bootloader
Customised devo 7e (128k) Deviationtx

Hello! Can You share your code? I want to run deviation on maple mini and use hp4067 (16 ch multiplextor) for extra pins.
But now i have problems with bootloader - standart bootloader from devo7e seems to be not working on maple mini. And I can't find sources of bootloader.

edit: build for W25Q16 attached. No way for me to test this though...


How can I change this code, can get me a screenshot of the, help me, I'm a novice?

How to change the code, cancel the greeting of no 6936 module "Missing Modules" “OK” ? Can you explain, thank you.
