I am familiar with Standard Pheripheral Library on STM32F100 MCU.
====
The problem is that on nucleo-053 (SPL is not available for this MCU) I cannot make USART working properly.
I generated the code using CubeMX 4.2 (USART2 enabled, NO parity, 1 stopbit, 8 data bits). When I use the following piece of code:
uint8_t pData[40];
int k;
for(k=0;k<40;k++){pData[k]=48+k;}
HAL_UART_Transmit(&huart2, pData, 40, 10);
only numbers and @ are sent correctly. Letters ('abcd', etc ) are displayed as if they have extended ASCI codes (extra bit was added in front of the original code making it extended code). I know that for 9B & parity the HAL driver plays this way. But it's not the cae, I guess (no 9B & parity).
I do not use physical uart port - Virtual COM is used (ST-link 2.1 feature).
===
Anyway, could you please share USART code example for nucleo-L053?
Thanks,
Bogdan
