Arduino for STM32

Try to downgrade Adafruit_GFX library from library manager.
I founded that last version that doesn't require Adafruit_BusIO library is 1.7.2
It will compile, but i can't say will it work.

Currently I'm focused on uploading custom Arduino program to DSO, which happens to be quite problematic. What problem do you have? I've just tried my DSO138 . After shorting JP1 and JP2, and pressing reset, i successfully flashed and tested firmware files (DSO138-113-13801-061.hex and DLO-138_switc...

Can it be overclocked to 128Mhz?

Install (add) Arduino DUE from board manager. As I recall, that is what is need to install gcc compiler for Roger's core.

Thanks. My collections of cheep-o-boards is now fully supported :-) Time to update my sketches. Just a few quick question, for clarification : - For STM32F401CC and STM32F411CE, "BlackPill" versions is with 25Mhz crystal, and "generic" is with 8Mhz crystal? - About interrupts void irq_handler(Hardwa...

Is Roger's Core sort of dead? I don't think it's dead, but rather at peek of it's glory. IMHO, if you are planning library only for Blue pill, then Roger's core is better choise. It's not that it can't be ported, but if it's made for stm32duino hal core, then same code can be compiled for different...

Thank you, added to favorites. Might as well register there too.

Hi. I guess i could write word or two here. My hobby is just basic electronics, building useless stuff just for fun. I am not programmer, but i learned to do stuff in Arduino IDE just by googling (a lot). By the time i switched from Arduino UNO to Blue Pill, old stm32duino site went down, so i final...

Intresting choise of pins PA9/PB6. Is that without timers for hsync/vsync? And such small memory footprint. Recalculating every (second) line based on chars, not as bitmap. And probably streaming that data with dma to portC?
Can't wait to see the code.

I don't know for sure if integer in Arduino IDE is 16bit or 32bit signed value, but setOverflow accept 32bit unsigned value.

Try with:
or better:
Also, i don't think you need to pause timer at all.
