I need to transmit two buffer trought HAL_UART_Transimit_DMA. I wrote in the code two consecutive command to do it but when I run the code, HAL_UART_Transimit_DMA do not return HAL_OK. It return HAL_OK only in debug mode stepping with F6. Why?

uint8_t slv_add[] = {0xF1, 0x0A, 0x00, 0x57, 0x53};                            if(HAL_UART_Transmit_DMA(&huart1, &slv_add, (sizeof(slv_add)/sizeof((slv_add)))) != HAL_OK)Error_Handler();uint8_t cell_sel[] = {0x91, 0x00, 0x0D, 0x06, 0xA8, 0x6E};      ...

Where can find the MTBF/FIT data of STM32L071CBT6?

STM32L422CB, low power consumption in capacitive proximity by single channel wake up source.

Dear All,We are planning to use STM32L422CB MCU in our application, but for low power consumption we are expecting capacitive proximity by signle channel or simple wake up by proximity.Somehow, we are not able to find out exact current in low power s...

Is there a software addon, SDK or examples for the apple MFI program for STM32 available?We are already MFI members.Thanks,Gabriel

Why toggling of Port E inside the timer 2 interrupt handler only work if the APB1 prescaler is set to /2 or /4 only?

I have a Timer 2 interrupt handler  which will toggle the Port E output. My MCU is STM32F407 running at 168 Mhz. I found that the toggle code inside the interrupt handler only work if the APB1 prescaler is set to /2 or /4 only. Slower ABB1 frequency...

B-U585: Qualify SSID with space: Not good!

Hello,the B-U585 Demo when asking for the SSID qualifies a name with a spacebar. Problem is, that many SSIDs contain a space by itself, like "FRITZ!Box 7530 ..." or "Galaxy ...". As the application does not echo what is sees, useres are left in the d...
