Re: RTOS SDK 1.3.0 UART_SetBaudrate undefined issue

This works for me.

UART_SetBaudrate(UART_Port uart_no, uint32 baud_rate)
{
WRITE_PERI_REG(UART_CLKDIV(uart_no), (UART_CLK_FREQ / baud_rate));
}

I could change the baud rate to 115200.

Hi,
I add driver line in Makefile follow your advice, and copy driver folder(copy from driver_lib/) into projet_template/, and copy driver header file into project_template/include/
Currently, a new error occur as following.

hw_timer.c: In function 'hw_timer_init':
hw_timer.c:79:5: error: passing argument 2 of '_xt_isr_attach' from incompatible pointer type [-Werror]
_xt_isr_attach(ETS_FRC_TIMER1_INUM, hw_timer_isr_cb, NULL);

Hi,

You can check the makefile whether it contains the "driver" or not.

Code:

SUBDIRS=    \
   user    \
   driver

Thanks for your interest in ESP8266 !

RTOS SDK 1.3.0 UART_SetBaudrate undefined issue

2016-02-04T10:02:52+08:00

I try to add one line(UART_SetBaudrate function) in examples/project_template/user/user_main.c but compile fail. What configuration needed to use APIs in examples/driver_lib/ ?

Code:

#include "esp_common.h"
#include "uart.h"

/******************************************************************************
 * FunctionName : user_init
 * Description  : entry of user application, init user function here
 * Parameters   : none
 * Returns      : none
*******************************************************************************/
void user_init(void)
{
   [color=#FF0000]UART_SetBaudrate(UART0, 115200);[/color]
    printf("SDK version:%s\n", system_get_sdk_version());
   printf("ESP8266 chip ID: 0x%x\n", system_get_chip_id());
}
