Arduino for STM32

Sure dannyf, is true.

Hello dannyf , sure, you are right. In my case at my age 68, having programmed (very skillfully and in absolute assembler) my first M6800 in the 70s, I have spent most of my life programming in the 8 bit world. And made a living out of it, despite being an analog and discrete digital design engineer ...

Yes, solves a problem !

Hello hobbya , thank you for this excellent information.
I will take a closer look tomorrow, but I find interesting the 6 pin ST-Link V2.1
However I understand that the VCOM port ends in TX/RX pins and that these pins need to be connected to TX/RX in the Bluepill (STM32F103C8T6) with 2 wires. If so ...

Hello friends, after some time, I would like to add something about my newbie experience.

I started using the bootloader but...

I reached the point in which I had to reFLASH the HID bootloader each time before Arduino uploads , because the bootloader under certain conditions, got corrupted. Later ...

As I had to solve my problem fast because I need STM32 for new pending jobs, I decided to do the following:

1 ...

khoih-prog I will always take a look at your advices. But my problem is how to register an interrupt vector or pointer from an interrupt event generated by the timer, in my case F1 TIM! or TIM2 .

I already tested your library, but it was slow for my purposes and need to have some more control ...

Hi dannyf , I need your help with this.
I spent almost the whole day to try to make this work.
Some values maybe wrong, but with my errors in the code, I can't make this thing interrupt.
Could you check my code, taken from the one you posted before?
Surely it must be simple solution. Excuse my ...

dannyf , I have your initialization function for TIM2 running, from you previous post:

I will ask you to teach me how to use TIM2CH1toPIN()
The compiler complaints here:
RCC->APB2ENR |= RCC_APB2ENR_AFIOEN; //enable AFIO
