Arduino for STM32

Hi feluga was wondering if your VGA driver could run on a LPC1768/9 (also Cortex M3...) I've no idea about the instruction set and registers differences between these processors and a STM32F103, and I'm not low level enough to understand the datasheets. The idea being to add a VGA output to a 3D pri...

Many thanks ! 2H45AM here, just flashed a bootloader on another BP, will test all this tomorrow... I knew these threads. But when I read "DMA" and "SD card", I stopped reading immediately... By the way I understood why the example I was trying to use (extremely simple) was "...

Most of the work is done. Switching the u8glib driver from ST7920 to SSD1306 made things much easier (encoding is more straightforward). I can now display an image I capture from the SPI bus. The SPI master runs u8glib (as does Marlin) on a Nano. The SPI slave also runs on a Nano, as I couldn't get ...

stevestrong It is not about using a SPI display, it is about emulating it. It's a bit different : I want to receive and read data, build a bitmap and send it to VGA. I've a ILI9341 in the drawers, but I doubt it will help : a color TFT will give more complicated data. This being said, you made me r...

Thanks for the answer. VGA will be the last task (but is the easier). Meanwhile, reading more, I discovered the sources I found on Git are a PlatformIO project. Don't really like VSCode, but better than nothing. For some reason, I didnt see "platformio.ini" while exploring subdirectories. ...

Hi, I'd like to build a ST7920 emulator that outputs a VGA or composite signal. I found only one open sourced ST7920 emulator, on the BigTreeTech Git ; it outputs to a color TFT. For now, it is mostly about reading data formatted for this ubicuitous 128x64 monochrome LCD. Unfortunately, it seems to ...

Hi @ag123 (see your post on page 2) I went there after I was googling ; in fact I was trying to get to the forum created by Vassilis Serasidis ; it disapeared ! Are STM32 forums doomed ??? I wanted to update the thread about a new version of my KiCad libraries for Blue/Black Pill In the post page 2 ...
