can not enter the callback function about UART0

2433841893 — Tue, 18 Sep 2018 07:32:04 GMT

I am working on the JN-AN-1189, and I want receive data from UART0.

The code as below:

PRIVATE void vUart_Init(void)
{
vAHI_UartEnable(E_AHI_UART_0);
vAHI_UartReset(E_AHI_UART_0, TRUE, TRUE);
vAHI_UartReset(E_AHI_UART_0, FALSE, FALSE);
vAHI_UartSetBaudRate(E_AHI_UART_0, E_AHI_UART_RATE_115200);
vAHI_UartSetRTSCTS(E_AHI_UART_0, FALSE);
vAHI_UartSetControl(E_AHI_UART_0, FALSE, FALSE, E_AHI_UART_WORD_LEN_8, TRUE, FALSE); /* [I SP001222_P1 279] */
vAHI_Uart0RegisterCallback ( APP_myisrUart );
vAHI_UartSetInterrupt(E_AHI_UART_0, FALSE, TRUE, TRUE, TRUE, E_AHI_UART_FIFO_LEVEL_1);
}

PUBLIC void APP_myisrUart(uint32 u32Device, uint32 u32ItemBitmap)
{
unsigned int irq = ((*((volatile uint32 *)(UART_START_ADR + 0x08))) >> 1) & 0x0007;
uint8 u8Byte;
vAHI_UartWriteData(E_AHI_UART_0, 0x33);
vAHI_UartWriteData(E_AHI_UART_0, 0x33);
if (irq & E_AHI_UART_INT_RXDATA)
{
u8Byte = u8AHI_UartReadData(E_AHI_UART_0);
vAHI_UartWriteData(E_AHI_UART_0, u8Byte);
//if(ZQ_bQueueSend(&APP_msgSerialRx, &u8Byte) == FALSE)
//{
// /* Failed to send the message to queue */
//}
}

if (irq & E_AHI_UART_INT_TX)
{
/*if(ZQ_bQueueReceive(&APP_msgSerialTx, &u8Byte) == TRUE)
{
vAHI_UartWriteData(E_AHI_UART_0, u8Byte);
decrement activity counter for dequeued data
}
else
{
disable tx interrupt as nothing to send
UART_vSetTxInterrupt(FALSE);
}*/
}
}

Note: I have seen the suggestions in JN5168 UART vAHI_Uart0RegisterCallback() Using, but it no effects.

Hi Gao,

Did you set the direction for that specific pins as an input?

Please look the next community post.

Thank you for your reply.

I have set the direction for the DIO7 as an input, but it no effects.

I am working on the JN-AN-1189.

Have you reproduced this problem on the JN-AN-1189?

Can you normally use UART0 to receive data on JN-AN-1189?

The codes as follow:

#define UART0_RXD (1<<7)
#define UART0_TXD (1<<6)

PRIVATE void vUart_Init(void)
{
vAHI_DioSetDirection(0, UART0_TXD);
vAHI_DioSetDirection(UART0_RXD, 0);
vAHI_DioSetPullup(0, UART0_TXD);
vAHI_DioSetPullup(UART0_RXD, 0);

vAHI_UartSetRTSCTS(E_AHI_UART_0, FALSE);
vAHI_UartEnable(E_AHI_UART_0);
vAHI_UartReset(E_AHI_UART_0, TRUE, TRUE);
vAHI_UartReset(E_AHI_UART_0, FALSE, FALSE);

vAHI_Uart0RegisterCallback ( os_vAPP_myCoordisrUart );

vAHI_UartSetBaudRate(E_AHI_UART_0, E_AHI_UART_RATE_9600);
vAHI_UartSetControl(E_AHI_UART_0, FALSE, FALSE, E_AHI_UART_WORD_LEN_8, TRUE, FALSE); /* [I SP001222_P1 279] */
vAHI_UartSetInterrupt(E_AHI_UART_0, FALSE, FALSE, TRUE, TRUE, E_AHI_UART_FIFO_LEVEL_1);

}

Hi Gao Lei,

DId you modify the makefile? Are you seeing the debug UART?

What is the example that you are selecting in the JN-AN-1189? I will try by my side.

Mario
