Arduino for STM32

for the official core there is one more thing you could try HAL
https://visualgdb.com/tutorials/arm/stm32/spi/
just that i've not tried this myself. stm32 HAL is actually c code rather than c++ codes.

welcome do take some time to read this 1st

think cube ide has option to select the host otg driver. possibly 'more complicated' since it needs to poll and enumerate the devices. i think there could be additional circuit requirements, e.g. that for usb host maybe the resistors should be pull down rather than pull up. think the mass storage pr...

this is going to be a weird suggestion you may like to try the libmaple core as the SPI implementation is different (pretty much written from scratch) https://github.com/rogerclarkmelbourne/Arduino_STM32 note that the libmaple api isn't really compliant with every aspects of the arduino api. Hence, ...

this would seem a little out of the norm, but a few things could help: - e.g. for spi (just SPI itself not the cpu core) try to run it at a lower speed, this may help that is normally done with the SPISettings() structure or class https://www.arduino.cc/en/Reference/SPI https://github.com/stm32duino...

that soldering is 'quite ok' never mind all that blobs, mine is quite as bad :lol: oh and for maple mini (clones) my common hack is to buy those cheap 32768 crystals and just solder them at the rtc osc pins https://www.aliexpress.com/af/32768.html?d=y&origin=n&SearchText=32768&catId=0 bu...

it could be related to spi, try to reduce the spi speeds to see if it helps.

average needs to be done on the cpu, the analog alternatives are to low pass filter it (e.g. rc filter) before reading it with an adc

I think the main issue is to find a universal tool which instantiate the USB DFU interface on all OS which allows the upload. And Java is the one which can be used independent on the platform. Unless one develop different tools for each platform in part. i think that java-loader.jar app's key use i...

i think these problems may have something to do with the dicey windows dll environment. if i'm not wrong jssc is actually a serial driver / connector library https://github.com/java-native/jssc this is apparently used by processing and that java-loader is apparently written in processing. if you are...
