Re: Recomendations for working components - TFT, OLED, ..

The most used LCD screens are the ILI9341 SPI based ones, they come in 2.4 inch and other sizes. (note there are parallel and SPI versions, but SPI is most well supported and takes far less wires) We use a modified version of the Adafruit graphics lib, so you should be able to install additional fon...

Re: ST-Link Vs Jlink

For the STM32F103, the MCU can be directly flashed via USB to Serial or some sort of SWD programmer JLink, BlackMagic Probe and ST-Link are all SWD programmers. There other types of SWD progamers, but my Libmaple based repo only supports upload via those three. The Maple bootloader (aka stm32duino b...

Re: ST-Link Vs Jlink

J-Link provides both JTAG and SWD hardware interfaces (and possibly others), but ST-Link only does SWD and SWIM At a hardware level both can be used to program the STM32 My LibMaple based Arduino Core has the option to upload via JLink for some boards eg. generic _stm32f103 aka Blue Pill However it ...

Re: Hello from Canada

welcome The F4 is a good platform for dsp as it has floating point, but I2S is also available on the larger F103 decvices. F4 support in my repo is not as well supported as the F1 ( about 90% of the forum members only use the F1), so you may want to look at STMs own Arduino Core or Danielef’s STM32 ...

Re: Hi from Norway.

Welcome

The STM32F7 discovery board is supported by the official Arduino Core.

https://github.com/stm32duino/Arduino_Core_STM32

You should post to viewforum.php?f=48 and ask about how this can be used with your board

CH340 emulator source code on github

Hi Guys I noticed this the other day, which seems to be Keil uVision project and source code for a STM32F10x to emulate a CH340 USB to serial adaptor. https://github.com/vdm-dev/stm32-ch340 I suspect if anyone really wanted to use it, the code could be converted to gcc, but it would be quite a lot o...

Actually, if there is anything that needs to be manually merged, can you just raise and issue so I don't forget

I finally managed to bring Wire lib on F4 to work, the new files are checked in with this commit: https://github.com/stevstrong/Arduino_STM32/commit/f83f33f97f5823f56baae7762321aa8d427d03f2 (Roger, don't ask me to prepare a PR, because I know now that I am not able to make a clean PR... :( .

Re: gd32f1(lqfp)

GD32 is no longer supported,because was found to not be totally compatible with STM32, and very few vendors sell GD32 boards, and those that do sell GD32 cost more than buying a much better STM32F4 board

I would recommend you buy a STM32F103 or STM32F4 board instead
