STM32CubeMX + MDK-ARM: using UART

[balazs]

Hi All,

I'm just starting up on development for STM32 Cortex M0 and M4, trying to use the CubeMX with MDK ARM to develop a simple communication protocol over rs485.However I could not find confirmations for my questions:- should I use the HAL SDK?- why my workbench does not support calls like: 

USART_SendData(USART2, 'X');

- where can I find detailed docs on the HAL SDK? (e.g. I still could not figure out the unit for the timeout parameter in the call HAL_UART_Receive - is that millis?)Any recommendations welcome!Thank you,Balas #hal #nucleo #usart #rs485

Hi Balas,

Please find below answers to your questions:

- should I use the HAL SDK?

• What do you mean by the HAL SDK ? STM32CubeMX ? if yes, you can use the HAL UART driver for RS485 vi the STM32CubeMX code generator or on a standalone example.

- why my workbench does not support calls like: 

USART_SendData(USART2, 'X');

• The STM32CubeMx is used only for protocol initialization not for data transfer.

- where can I find detailed docs on the HAL SDK? (e.g. I still could not figure out the unit for the timeout parameter in the call HAL_UART_Receive - is that millis?)

• You can refer to the UM1725: Description of STM32F4xx HAL drivers available
