New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

gif-stm32u0.gif

I am using UART1 of STM32F407VE in interrupt method. I am checking loopback method.But I am losing some characters . I am using docklight serial monitor to send 20-30 set of characters.I need to store around 255 bytes of data to a buffer.

This is my interrupt handler...void USART1_IRQHandler(void)   { uint8_t data;   HAL_UART_IRQHandler(&huart1); __HAL_UART_CLEAR_FLAG(&huart1, UART_FLAG_RXNE); data = (uint8_t)(huart1.Instance->DR & (uint16_t)0x00FFU); HAL_UART_Transmit(&hua...
