Hi,
i would appreciate help in writing a simple test code to read data from UART in interrupt mode.
I am a newbe here.
I started with CharECHO_UART example and i was able to connect a terminal emulator (using a USB-DB9 cable). Then using Tera Term i sent a file
to my board and in DMA mode i was able to read all bytes i received.
Then i try something like:
static ADI_UART_HANDLE hDevice;
static void UARTCallback(void* pHandle, uint32_t u32Arg, void* pArg) {
printf("UART CALLBACK!!!!\n");
ADI_UART_HANDLE pDevice = (ADI_UART_HANDLE)pHandle;
ADI_UART_EVENT event = (ADI_UART_EVENT)u32Arg;
uint16_t *data = (uint16_t*)pArg;
printf("complete buffer:%s\n", ReceiveBuffer);
/*
here's the problem: my ReceiveBuffer contains only the last char sent from Termina Emulator
*/
}
int32_t main(void) {
// open UART in bidirectional interrupt mode mode
adi_uart_Open(UART_DEVICE_NUM, ADI_UART_DIR_BIDIRECTION, gUARTMemory_interrupt, ADI_UART_BIDIR_INT_MEMORY_SIZE, &hDevice);
adi_uart_SetBaudRate(hDevice, 115200u);
adi_uart_SetConfiguration(hDevice, ADI_UART_NO_PARITY, ADI_UART_ONE_STOPBIT, ADI_UART_WORDLEN_8BITS);
adi_uart_RegisterCallback(hDevice, UARTCallback, (void*)0);
adi_uart_SubmitRxBuffer(hDevice, ReceiveBuffer, 2);
adi_uart_EnableRx(hDevice, true);
while (true){
// do nothing
}
}
The problem is i only get the last character sent from terminal. I need to catch all chars sent from terminal
Each message sent from terminal may have different length so i need to process each received byte individually
I searched a lot and was not able to find a basic example that help me to build a simple program that read from UART in interrupt mode
