Code Examples. In the above code, HAL_UART_RxCpltCallback will be called when the data reception is complete. Quite simply - I want to receive a character in UART1 via an Rx interrupt and transmit it on UART 6. Each interrupt has a flag that is raised (set) when the interrupt occurs. Each interrupt flag has a corresponding enable bit – setting this bit allows a hardware module to request an interrupt. Most interrupts are maskable, which means they can only interrupt if 1) enabled and 2) the general interrupt enable (GIE) bit is set in the The solution for generating an interrupt following reception of an arbitrary length of data is to enable the UART RX Timeout interrupt (AM_HAL_UART_INT_RX_TMOUT).
