Arduino for STM32

On the ST core you can remap the spi, i2c and serial pins: https://github.com/stm32duino/wiki/wiki/API#spi

You can also can use a different library, the default arduino SD library only supports the default SPI, but on other libraries you can use a different SPI port.

Hi, the stlink option it's still there, now it's called "STM32CubeProgrammer SWD" on arduino ide, but you have to download some kind of software with the same name on the ST site.

Thanks for posting the link to the VET6. I have a board with a STM32F103VCT6 that I never got around to creating a variant. It looks like the main difference is that the VCT6 has 256K flash instead of 512, and 48K ram instead of 64. All the pin names seem to be the same at first glance. Hopefully a...

Hi, the ST core supports a lot of the ST MCU's but the individual variants may not be available, you can add one yourself using this guide . I made a variant for this STM32F103VET6 MCU (I just updated the installation info that also I just noticed that I forgot to add :lol: ) So this variant should ...

Hi, so with this boards.txt segment: ################################################################################ # Generic L1 GenL1.name=PILL_L1 GenL1.build.core=arduino GenL1.build.board=GenL1 GenL1.build.extra_flags=-D{build.product_line} {build.enable_usb} {build.xSerial} # PILL_L1 Board # S...

The bare IC are still OK to buy on ali, I've bought flavors of the STM8, F030, F103, F405, F407 and so far so good even when I pick for the cheapest price :lol: . Also, dismiss a dispute for the bare IC should be way more difficult for the seller or ali. When I was looking for the F030C8 IC I saw a ...

Hi, there is a guy who goes by the "cbm80amiga" nickname who has some amazing libraries and a yt channel showcase them: https://www.youtube.com/user/cbm80amiga/videos https://github.com/cbm80amiga?tab=repositories I think he uses dma and the spi at 36mb on the bluepill, no overclock needed.

is it difficult to hand solder stm32 mcus? i've been thinking about this option since those cks32f103 clones seemed to be getting more prevalent. but of course these days there are stm32f401 & f411 boards https://www.aliexpress.com/wholesale?catId=0&SearchText=stm32f401. and they are priced...

Yep, I've made a few custom boards including an F405RG, the MCU's are pretty cheap on ali so...
