Resolved! F401RE Nucleo UART_Printf example produces faulty formatted serial output bytes for ODD parity, but correct for parity NONE and correct when changing settings to 9 bits while receiver is at 8bits.

Hello,During my exploration of the F401RE board, I tried to make the uart_printf example work correctly.Capturing the output of the main MCU via CN3-RX pin to a PicoScope 5440, an CH340 and on board F103 USB interface MCU all lead to the same conclus...

Has anyone transcoded the SHT30 Sensor for STM32L0 or any series? I didn't know how to adapt the I2C pins while exporting the libraries. For example how can I adapt these parts from arduino to stm32?

I am trying to read UART and to hold on rx_data array. when I send "AT" to rf module it returns "OK" , but on my code I cannot receive anything from UART. and help appreciated

uint8_t tx_data[2] = "AT"; uint8_t rx_data[10]; HAL_Delay(1000); while (1) {  HAL_UART_Transmit (&huart1, tx_data, sizeof(rx_data) , 250);  HAL_Delay(500);  HAL_UART_Receive(&huart1,rx_data, 20,1000);  HAL_GPIO_TogglePin (GPIOA, LED_Pin);  HAL_Delay(...

Resolved! Multi-Channel I2S Hardware Design on an STM32F413/423

The microcontroller will be doing little else besides some very light processing on the audio data. The I2S source has a single MCK, SCK, WS, and 4 stereo outputs (3 of which will be used), and the I2S source can ONLY function as a master device, le...
