I’m following the (ok, 3 year old) STM32 UART tutorial here:

https://visualgdb.com/tutorials/arm/stm32/uart/

As the tutorial is old, my VisualGDB UI is a bit different. One place of interest: I have 3 options for the LEDBlink sample (HAL, StdPeriph, and FreeRTOS).  I leave the default at LEDBlink (HAL). There’s also a checkbox not show in tutorial “Support Legacy HAL API”. I leave it checked.

Blink works fine. So I proceed to step 7 to add some UART code.

When doing so – pretty much all of the UART macros are undefined, even when adding the suggested libraries as shown:

I wonder where #STM32 #USART config is found, if not in <stm32f10x_usart.h> Perhaps tutorial out of date. https://t.co/JP6h4DFs0K pic.twitter.com/pVUQpWtGvC

If I change the sample code to LEDBlink (StdPeriph) the only compile error is that unsignedchar is an unknown type for  USART_ReadByteSync(USART_TypeDef * USARTx)   ha! as it should have a space in there between unsigned and char 😉 perhaps update the tutorial for others that might not know that.

However, curiously with StdPeriph my LED no longer blinks (GPIOC, pin 6 in both instances)

Can you please add some clarification to this? Is there some documentation on the HAL features? I googled it and didn’t really find any sort of VisualGDB overview on this topic.

I am using a STM32 Smart V2 (with STM32F103C8T6 – or is that xCBT6?) with Visual Studio 2017 (same result in 2015) with VisualGDB-5.2.14.1389.msi

Any insight on this will be appreciated, thanks.
