  • UART_TwoBoards_ComDMA: update following the change done in UART driver to fix the DMA transmit process (the code has been updated to avoid waiting on TC flag under DMA ISR, UART TC interrupt is used instead):
    • Configure and enable the USART IRQ in HAL_UART_MspInit() function
    • In stm32f4xx_it.c file, USARTx_IRQHandler() function: add a call to HAL_UART_IRQHandler() function

V1.1.0 / 26-June-2014

Main Changes

  • Common update for all Examples
    • Update EWARM startup file for all projects to cope with compiler enhancement of the V7.x version
