How to program STM32 Development Board

Question

I'm a total beginner with programming ARM microcontrollers, but I do have experience with AVR and PIC microcontrollers.

A few days back I have purchased a STM32F103VET6 development board from eBay. I'm now trying to program this board but I don't know where to start. I have also received a CD which contains some datasheets and some documents (all in Chinese).

Could someone tell me how to start? Or does someone have some source samples?

I have already installed Keil uVision4. I also have a J-link debugger.

I have blinker example if you want to see

#include "stm32f10x_conf.h"

/* led connected to a gpio pin */
#define LED1_PIN    GPIO_Pin_0
#define LED1_PORT   GPIOB
#define LED2_PIN    GPIO_Pin_3
#define LED2_PORT   GPIOC
#define LED3_PIN    GPIO_Pin_0
#define LED3_PORT   GPIOA
#define LED4_PIN    GPIO_Pin_0
#define LED4_PORT   GPIOE


/* user functions */
void delay(unsigned long count);

int main()
{
    GPIO_InitTypeDef GPIO_InitStructure;



    /* enable clock on GPIOB peripheral */
    //RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
    RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOB | RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOE | RCC_APB2Periph_GPIOA, ENABLE);                          


    /* set pin output mode */
    GPIO_InitStructure.GPIO_Pin = LED1_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(LED1_PORT, &GPIO_InitStructure);
    //LED 2
    GPIO_InitStructure.GPIO_Pin = LED2_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(LED2_PORT, &GPIO_InitStructure);
    //LED 3
    GPIO_InitStructure.GPIO_Pin = LED3_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(LED3_PORT, &GPIO_InitStructure);
    //LED 4
    GPIO_InitStructure.GPIO_Pin = LED4_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(LED4_PORT, &GPIO_InitStructure);
    while(1)
    {
        GPIO_SetBits(LED1_PORT, LED1_PIN);  // set pin high
        delay(2000000);
        GPIO_ResetBits(LED1_PORT, LED1_PIN);    // set pin low
        delay(2000000);

        GPIO_SetBits(LED2_PORT, LED2_PIN);  // set pin high
        delay(2000000);
        GPIO_ResetBits(LED2_PORT, LED2_PIN);    // set pin low
        delay(2000000);

        GPIO_SetBits(LED3_PORT, LED3_PIN);  // set pin high
        delay(2000000);
        GPIO_ResetBits(LED3_PORT, LED3_PIN);    // set pin low
        delay(2000000);

        GPIO_SetBits(LED4_PORT, LED4_PIN);  // set pin high
        delay(2000000);
        GPIO_ResetBits(LED4_PORT, LED4_PIN);    // set pin low
        delay(2000000);
    }
    //return 0;
}



void delay(unsigned long count)
{
    while(count--);
}

Also look at the very affordable STM32 Discovery board. Grab a copy of the texane/stlink project on Github, which has a very helpful tutorial along with good software tools for getting started.

You can get the board at various places.

Here's the stlink project on Github.

You'll find lots of info on programming the STM32F103 here:

http://www.st.com/internet/mcu/product/164486.jsp

with plenty of examples.

You'll find things much easier with one of the ST boards, such as this one:

http://www.st.com/internet/evalboard/product/250863.jsp

They are very inexpensive and plenty of documentation and examples are available.
