Arduino for STM32

check if you are accidentally installing something in ram? flash address normally is 0x8000000

+1 Thanks !

this is an old favorite topic in the old forum

ok finally i ordered a couple f401, cos it seem like 'everyone else has it' :lol: the f411 seem to have SD hardware support, f401 nil f4* and even f303cc doesn't feel the same as the stm32f103, they are faster even for the same clock speed according to the flyer, and specs it has that ART accelerato...

i've occasionally used imgur https://imgur.com/ but i'm not sure how long the images would be retained there. so those images may 'disappear' after a while. slighly larger sizes say < 200k would probably help, my guess is compression can mostly fit many in but there would still be many that exceed t...

one way though is to explore dma https://www.st.com/content/ccc/resource/technical/document/application_note/group0/91/01/84/3f/7c/67/41/3f/DM00236305/files/DM00236305.pdf/jcr:content/translations/en.DM00236305.pdf chapter 5 Arbitrary waveform generation using timer DMA-burst feature and this is pro...

well, it means your timer is generating the interrupts as you expect, so if you expect your timer to say run at 100khz that would be 100k interrupts per sec + 1000 interrupts from systick. so say if you increase the loop count to say 101000 / 2 and split the intervals between led on - led off it wou...

my guess is one could check if other interrupts (e.g. usb sof every 1ms and systick every 1ms used for delay(n) ) could be occuring. one of those tricks i do is place asm("wfi"); in loop(), that is nearly the same as delay(1) and have an variable, counter checking the number of "wfi&q...

not too familiar with avr's too but DDRx registers basically gives the direction of a pin being input or output? http://maxembedded.com/2011/06/port-operations-in-avr/ i'd guess the arduino api pinMode(pin,mode) gives similar functionality, e.g. pinMode(pin, INPUT) and pinMode(pin, OUTPUT) , probabl...

it is interesting that the 'ancient' uart is still relevant today, simply because for one thing, framing and parity checks is there. and it literally makes that comms channel clean as noise (just press reset on target, without framing checks, it generates 'extra' bytes) and corrupted bytes are simpl...
