Arduino for STM32

This is simple by looking at other models such as the 24AA024H: it is very easy to understand how it works.

I suspect that the first model I mentioned in my question should be a very particular one...

So problem is solved.

Hello, I would like to use an external EEPROM with a STM32 Bluepill, and in order to save the pins to be used, I imagine (maybe i am wrong) to use an EEPROM with a I2C interface, such like this one: https://www.mouser.fr/ProductDetail/Microchip-Technology/24FC16-E-P?qs=xZ%2FP%252Ba9zWqamR%252BXPFPB0...

Problem solved, and the cause was simpler than you suggested: the STM32 Bluepill has its bluit-in Led connected to PB2, and not to PC13 as usual !! See image: Bluepill.JPG I just had to change the code in the program from "#define LED_BUILTIN PC13" to "#define LED_BUILTIN PB2" an...

I have been using Arduino Nanos for years, but I am unable to transfer a sketch to a STM32 Bluepill (STM32FC103C8). I have followed this tutorial : https://www.sgbotic.com/index.php?dispatch=pages.view&page_id=48 , and for information I have previously trried using PlatformIO under VScore: Platf...
