Arduino for STM32

If you have a V2 you can change it to 2.1 if you have the time.

For me it was easier to bay one even if have som V2 but most i get is not whith STM32F103 chip now to days
Blaupill to ST-link is also good .

Find this and order one.
Some one have make clone as you can get on a real ST board but with better "Box"
Works good with Cubeprog.

Well I take the setting from WeAht clock setting and put them in CubMx and it did not complane and get the same setting for clock.
I find in variant_B_G431B_ESC1.h
/* HAL configuration */
#define HSE_VALUE (24000000UL) and if rember right this board have 24Mhz cristal.
And set that in variant ...

I order one and it works :)
Have anyone made a variant of this board in arduino for STM32 ?
I was setting the HSE with a extern "C" from CubeMX or the clock file from WeAct at 170Mhz but delay() will 3 time as long ?

extern "C" void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct ...

Debug.jpg Now I get a blackpill F411CE to work to debug.
To get to see the Cortex Peripheral Register I hade to put the STM32F411.svd fil and the debug_custom.json in the sketch folder .
{
"svdFile": "STM32F411.svd"
}
Some how it did not work to have it on there i find it.
C:\Program Files ...

Thanks it work for me W10 2.0.3 on F103 and ST-link2
And on F303 Blackpill and Olimex F3

I am using code from this on F303 and it works good.

It should work for F103 to using a serie to USB , Upload with ST-link

Been a long time to not log on the to the "new forum"
Have make some project with Rogers core and now Olimex F3 on ST core that i have BMS on CAN and some DYNAMIXEL servon to control the hybrid drive for sail boat.

I hade same problem with Olimex F3 board. On other board BlackPill F303 it work with as i should
The frekvens from cristal was not stabel .
The found you can make drive stronger an then I get right frekvens.
And could use the the hardware compensate in RTC->CALR register.
Here is som exempel code ...
