UART DMA TX occasional errors
Once a while my Error_Callback() of the UART DMA RX/TX is triggered and I can't make sense out of it.In the HAL_UART_ErrorCallback the values areHAL_UART_GetState(huart) == 32 // HAL_UART_STATE_BUSY_RX HAL_UART_GetError(huart) == 16 // HAL_UART_ERRO...
How to find a Temperature on STM32F303K8
Hi, Everyone.I'm tring to make adc sensor works, to find a temperature.I found AVG_Slope and V_25 in the datasheet: AVG_Slope = 0.0046 V_25 = 1.46And I used V_Ref = 3.0f and N_Bit = 4096fThis is My code (Only for adc_complete conversion)void HAL_ADC_...
