I do UART periodically transmitting using DMA. Without interrupt it works perfectly. I tried to add interrupt functionality and have a problem. the dma interrupt has been called (void dmacb()), but after that faultISR is called... What am I doing wr...
10/14 Doc ID 14762 Rev 2 AN2781 5 CPU workload CPU workload The interrupt service latency could be critical for both transmit and receive processes, especially while using a higher communication speed. The user has to handle both processes by interrupt services of higher priority to prevent ...
/* Registers the UARTIsr in the Interrupt Vector Table of AINTC. */ IntRegister(SYS_INT_UARTINT2, UART2Isr); /* Map the channel number 2 of AINTC to UART2 system interrupt. */ IntChannelSet(SYS_INT_UARTINT2, 3); IntSystemEnable(SYS_INT_UARTINT2); ...
I'm trying to get the interrupt to work for my UART. I'm trying to use UART2 for my application. Without interrupt, I can send data successfully. After I enable the interrupt, I can see that the interrupt is happening. It goes to _int_default_isr(void *vector_number) in...
I have a question regarding uart_interrupt.c: How does the ISR (DEMO_UART_IRQHandler) get invoked? I cxhanged the example code from using UART0 to using UART4 and have updated the macros like this: #define DEMO_UART_IRQn UART4_RX_TX_IRQn #define DEMO_UART_IRQHandler UART4_R...

The SPRUN bit is automatically cleared by the SPI cell at the end of transmission or reception and an interrupt request can be generated. It is associated with interrupt vector #2. The division ratio between the core clock (Fosc divided by 13) and the clock supplied to the Shift register ...
