JN5169 UART1 SEND DATA

fangliang2316 · ‎06-25-2019

Hi,

I am working with the ZigBee HA Intruder Alarm System. I am working with JN-AN-1201.

I need to communicate with another MCU through uart1. Where do I need to configure and modify?

Sebastian_Del_Rio · ‎06-25-2019

Hi Liang, I hope you're doing well!

To add functionality for UART1, you first need to set it up, and you can do so in the APP_vInitialise part of your program (inside the app_start.c source file). You can base your initialization on the implementation for UART0 in the JN-AN-1217 Application note.

You'll have to create a new function based on the existing UART_vInit, but adapt the macros so it enables UART1 instead of UART0.

If you have any further questions, please let me know.

Best regards,

Sebastian

Hi Sebastian,

Thanks for reply!

We are now developing on the basis of JN-AN-1217. JN-AN-1201 and JN-AN-1217 are different software architectures. I'll do the following directly. uart1 still can't send data. Can I give some suggestions based on JN-AN-1201?

PUBLIC void UART_vInit(void)
{
bAHI_UartEnable(E_AHI_UART_1, txbuf,(uint8)16, rxbuf, (uint8)127);

vAHI_UartReset(E_AHI_UART_1, TRUE, TRUE);
vAHI_UartReset(E_AHI_UART_1, FALSE, FALSE);

UART_vSetBaudRate(E_AHI_UART_RATE_9600);
vAHI_UartSetControl(E_AHI_UART_1, FALSE, FALSE, E_AHI_UART_WORD_LEN_8, TRUE, FALSE);
vAHI_UartSetInterrupt(E_AHI_UART_1, FALSE, FALSE, FALSE, TRUE, E_AHI_UART_FIFO_LEVEL_1);

}

My requirement is that UART0 output log, uart1 communicate with another MCU。

Best regards,

Liang

Hi Liang,

Could you please try checking the corresponding DIO pins for UART1 with a logic analyzer to see if they're outputting anything?

The pins for UART1 are:

DIO17: UART1 Clear to Send

DIO18: UART1 Request to Send

DIO19: UART1 TX

DIO20: UART1 RX

Please let me know of your results.

Best regards,

Sebastian

Hi Sebastian,

Thanks for your for reply.

Maybe I didn't have to describe it clearly. The chip model I chose was JN5169.

according to data sheet,the pins for uart1:

DIO14:UART TX

DIO15:UART1 RX

I have checked DIO14 pins and DIO11 pins,No data output.

Hi Sebastian，

Here is a supplementary description of the problems I encountered.

SDK: JN-SW-4168

example: AN-JN-1201

chip： JN5169

part A:

It is from JN-AN-1201,UART0 for log :

vAHI_UartSetRTSCTS(E_AHI_UART_0, FALSE);

DBG_vUartInit(DBG_E_UART_0, DBG_E_UART_BAUD_RATE_115200);

The log is ok

part B:

I want to add uart1 to communicate with another MCU.

void driver_uart1_init (void)
{
bAHI_UartEnable(E_AHI_UART_1,UART1_TX_BUFF,100,UART1_RX_BUFF,100);

vAHI_UartReset(E_AHI_UART_1, TRUE, TRUE);
vAHI_UartReset(E_AHI_UART_1, FALSE, FALSE);

UART_vSetBaudRate(E_AHI_UART_RATE_115200);

vAHI_UartSetControl(E_AHI_UART_1, FALSE, FALSE, E_AHI_UART_WORD_LEN_8, TRUE, FALSE);
vAHI_UartSetInterrupt(E_AHI_UART_1, FALSE, FALSE, FALSE, TRUE, E_AHI_UART_FIFO_LEVEL_1);

}

I doubt if there is a conflict between these two parts，part A and part B.

Best regards,

Liang

Hi Liang,

I'm sorry, I got confused with the default pin location of UART1 in the JN5169. The default pins are the ones you mentioned (DIO14 and DIO15).

The UART1 and UART0 setup shouldn’t interfere with each other. Could you please make sure that you're enabling and setting the priority of the UART1 interrupt correctly in the irq_JN516x.S file?

For example:

…

    .byte 0                 # PHY priority
    .byte 5                 # uart0 priority
    .byte 0                 # uart1 priority 
.globl  PIC_SwVectTable
    .section .text,"ax"
    .extern zps_isrMAC
    .extern ISR_vTickTimer
    .extern APP_isrUart
    .align 4
    .type   PIC_SwVectTable, @object
    .size   PIC_SwVectTable, 64 
    .word vUnclaimedInterrupt               # 2
    .word vUnclaimedInterrupt               # 3
    .word vUnclaimedInterrupt               # 4
    .word APP_isrUart                       # 5
    .word vUnclaimedInterrupt               # 6 
 ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

…

Also, could you please check if the UART1 pins are on high to check if the pins are set correctly?

Best regards,

Sebastian

fangliang2316 · ‎06-29-2019

Hi Sebastian,

I have checked UART1 pins,they are on high.

I confirm that I have set the priority level for UART1 in os_irq.s file（I coundn't find irq_5169.s in JN-AN-1201）.

in the file App_ZHA_ZONE_JN516x.oscfgdiag, I config the Uart1 interrrupt.

I have a question about how to configure the parameters in Makefile file.

Sebastian_Del_Rio · ‎07-01-2019

Hi Liang,

Could you check to see if you added the priority in the "os_PIC_ChannelPriorities" section if the .s file?

Also, could you try adding this to the bottom of your file?

os_vISR_Uart1_J:
    b.ori  r3,r0,os_vISR_Uart1
    b.ja   os_vISR_Uart1‍‍‍

Are you interested in the IAS profile?

Do you want to enroll your devices?

Best regards,

Sebastian

I use the IAS profile and I enroll my devices.

I succeeded in exporting debugging logs separately through UART0 or uart1. But I output logs through uart0, and through uart1 communicating with PC or mcu, uart1 cannot output data.Could you confirm this question, based on

JN-AN-1201.Thanks!

Best regards,

Liang

Hi Liang,

Could you please try changing the vISR_Uart1 to APP_isrUart?

In the function, you'll have to specify which UART you'll be using to communicate:

PUBLIC void APP_isrUart(void)
{
    unsigned int irq = ((*((volatile uint32 *)(UART_START_ADR + 0x08))) >> 1) & 0x0007;
    uint8 u8Byte;
 
    if (irq & E_AHI_UART_INT_RXDATA) {
        uint8 u8Byte = u8AHI_UartReadData(UART);
        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(UART, u8Byte);
            /* decrement activity counter for dequeued data */
        } else {
            /* disable tx interrupt as nothing to send */
            UART_vSetTxInterrupt(FALSE);
        }
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Also, can you send data if you're not using the debug?

Please let me know if that works.

Best regards,

Sebastian
