So I can't speak to how they might work, or not work! But I have used the PORT commands on the UNO and Mega boards and they work just fine there. Here's a page on PORT control using Arduino language.ĭISCLAIMER: I have yet to use the Arudino PORT commands in STM32 programs. Here's a page on PORT control using STM32 language.Īccessing-Reading and Writing to whole gpio ports of stm32 microcontrollers You can also access these ports directly as entire bytes instead of using digtitalWrite commands.

Just as a note, these stand for PC = PORT C, PB = PORT B, etc. Posted by: was using 13, 14, etc without the PC. Mostly it doesn't matter, but if you want me to change your transmission, for example, you might want to think twice! Perhaps you've gathered I'm a 'learn by your mistakes' person.

There's also not enough room near the pin holes to label them fully, so PC13 ends up being labelled C13, etc. The boards for NANOs and STM32F103s are not the same physical size! I assumed they were, so I was counting to the wrong pin number.

The stock Blink works on the blue pill because you can say 'BUILTIN' to define the LED, but with the STM32 series you have to use a different nomenclature: int LEDpin_1 = PC13 // Physical pin 2Īlso, again I have to blame my eyesight and overlooking the obvious. So I'm not the only one! Since I saw the obvious, I have been verifying the pins using LEDs with 470-ohm dropping resistors, and things work as advertised.

I'm looking all over the place for them only to realize that I've been wearing them the whole time. Posted by: they way I am with my glasses.
