Arduino for STM32

Hi, so yes, the pin naming stuff it's really over complicated.... so the Px_XX (example: PA_0) are the "real" pin names, those are defined within the CORE, all others are just an AKA: numerical pins and the PxXX (PA0) names, but the Px_XX cannot always be used, it will depend on the functi...

So I order some LM324 on SMD package but the seller send the DIP version, I don't have an use for those so I saw this method and decided to use it on this IC: https://coproch.cl/wp-content/cache/lm324_000_.jpg https://coproch.cl/wp-content/cache/lm324_001_.jpg The resistor it's an 0402, such waste o...

Are you using Roger's Core, right?, I used this code on the sketch to add get/put functionality: template <class T> void eeGet(int ee,T& value){ byte* p=(byte*)(void*)&value; unsigned int i; for(i=0;i<sizeof(value);i++) *p++=EEPROM.read(ee++);} template <class T> void eePut(int ee,T& val...

Using stlink on arduino ide doesn't need bootloader, serial or messing with the boot pins. But also, arduino ide creates a .bin file when compiles, it saves it on the OS temp folder, just check your compile resume log, it says something about an .ino.elf file, on the same folder it leaves the .bin f...

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 ...
