Re: SD library SPI pins remap

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.

Re: ST-Link and Blue Pill

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.

Re: STM32F103VET6 availabilty

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...

Re: STM32F103VET6 availabilty

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 ...

Re: Complaint about counterfeit STM32 chips - please read.

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 ...
