Arduino for STM32

Guys Many thanks for the effort, I ended up not pursuing the solution for the USB serial port, I've narrow down to the clock configuration and the On-OFF procedure that Roger's core does. My main issue with Roger's core was the return from sleep and the clock adjustment after that, but right now I c...

Hi fredbox, thanks for the support, All of those connectors and no SWD pins? I have a commercial STM32F103VET6 board that I program using either a ST-Link dongle or a USB/Serial adapter connected to USART1. I never could get any bootloader stable enough to be useful. That's very strange, I have a bu...

Even if your clock work well if the config is not properly set this will not work: ;) Anyway as the USB seems properly enumerated this should be fine. Could you share the schematics, please? Sure, here it is https://drive.google.com/file/d/1vZnHArGkR0_ABhNxIsWJ2Y7xfzeCYV8a/view?usp=sharing If that ...

Well in that case it is probably an USB clock issue. Which board you used ? Does it have an HSE ? which value ?... It's a self-made board, I've made the project following the most common stm32 board, like the bluepill ( the generic one) but using the High density VET6 model. I don't have this issue...

Hi fpiSTM, Yes, that's my current configuration. https://i.ibb.co/74Q21Nh/Capture.png even when I disable the configurations and create the USBSerial object, the interface doesn't work, also, I've reinstalled the drivers to make sure that the drivers were not wrong and tested with Zadig to see the i...

Thanks mrburnette but what I ment is that the USB serial doesn't print anything All other Hardware serial ports work ok, just the USB emulated one witch is named USBSerial on Arduino is the problem. Do you have any idea on what it could be, as I said it works with Rogers core, but it doesn't work wi...

Hi guys, I'm using a stm32f103vet6 with the last core(1.9.0) as I'm migrating from the Rogers core, as I'm looking for the LowPower mode. I'm using the generic bootloader from him, and I'm able to, using the "Maple DFU bootloader 2.0", with the USART support enable and the CDC with Generic...
