Arduino for STM32

Hello everyone,

I would like to have something like a continous ADC Average Value. Or at least maybe 1000 values that I can load from a buffer which is continously filled. But i don't want to use the CPU processing time. As far as I know that seems to be the functionality of DMA. Is this correct ...

Hey everyone :)
I'm using some Bluepills with a STM32F103C8T6 and a Custom made Board also with a STM32F103C8T6.
The custom Made boards communicates with the Bluepill Board. I'm using a Max485 UART/RS485 Transceiver. This Transciever has an Enable Pin which needs to be High to send data and low to ...

Hey guys,

I used another PC to try it again and it works - seems to have something to do with my notbook.

Hey,
sorry - I should have known that this have been not enough informations.
I'm using a Bluepill Board with STM32F103C8T6 Processor on it.
The bootloader was programmed with stm32Cubeprogrammer.
Upload is done in the Arduino IDE.
And I'm using the official core from https://github.com/stm32duino ...

Hey Guys,
I tried to use the HID Bootloader. And i Got this error message:

hey,

thank you for your reply and the informations!
But there is still the question about the bootloader right? or do I have to interpret this as a "no"?

Greetings!

Hey guys,

I had some problems using the HID Bootloader. (using ST Link to programm works fine. Serial.println() as well) After flashing the HID Bootloader the board wont be recognized. Also with Boot1 pin HIGH.
What I found out is, that I got some Boards with a fake processor called CH32F103C8T6 ...

Hey guys,

I would like to speed up my UART communication.
actually it looks like this:

I would like to increase the time between the bits where nothing happens.
I'm using a Bluepill Board with the offical core.
My Code looks like this:

#define SAMPLERATE 2000000 ...

Hey thank you for your reply!
I think, that goes beyond my programming skills...
Is there a plan to implement this feature?

I'm still a little bit confused by the cores, but it should be the official ST Core from https://github.com/stm32duino/BoardMana ... index.json
