Posted on November 02, 2011 at 10:16Hi,
I'm using:
- uVision 4
- STM32F10x_StdPeriph_
Lib_V3.5.0-> STM32F10x_StdPeriph_Template
-> STM32F10x_StdPeriph_
Examples -> USART -> Printf
I try to send data via USART3 and it doesn't work.
What i change for USART3:
1) I choose STM32100B-EVAL
2) Set in options device -> STM32F101CB
3) Check startup_stm32f10x_md_vl Include_target_build (but in STM32100B-EVAL template it was checked)
4) In stm32_eval.h file:
typedef enum
{
COM1 = 0,
COM2 = 1,
COM3 = 2
} COM_TypeDef;
5) In stm32100b_eval.h
/* ------------------------ USART 3 ------------------------------ */
#define EVAL_COM3 USART3
#define EVAL_COM3_CLK RCC_APB1Periph_USART3
#define EVAL_COM3_TX_PIN GPIO_Pin_10
#define EVAL_COM3_TX_GPIO_PORT GPIOB
#define EVAL_COM3_TX_GPIO_CLK RCC_APB2Periph_GPIOB
#define EVAL_COM3_RX_PIN GPIO_Pin_11
#define EVAL_COM3_RX_GPIO_PORT GPIOB
#define EVAL_COM3_RX_GPIO_CLK RCC_APB2Periph_GPIOB
#define EVAL_COM3_IRQn USART1_IRQn
6) In stm32100b_eval.c
USART_TypeDef* COM_USART[COMn] = {EVAL_COM1, EVAL_COM2, EVAL_COM3};
GPIO_TypeDef* COM_TX_PORT[COMn] = {EVAL_COM1_TX_GPIO_PORT, EVAL_COM2_TX_GPIO_PORT, EVAL_COM3_TX_GPIO_PORT};
GPIO_TypeDef* COM_RX_PORT[COMn] = {EVAL_COM1_RX_GPIO_PORT, EVAL_COM2_RX_GPIO_PORT, EVAL_COM3_RX_GPIO_PORT};
const uint32_t COM_USART_CLK[COMn] = {EVAL_COM1_CLK, EVAL_COM2_CLK, EVAL_COM3_CLK};
const uint32_t COM_TX_PORT_CLK[COMn] = {EVAL_COM1_TX_GPIO_CLK, EVAL_COM2_TX_GPIO_CLK, EVAL_COM3_TX_GPIO_CLK};
const uint32_t COM_RX_PORT_CLK[COMn] = {EVAL_COM1_RX_GPIO_CLK, EVAL_COM2_RX_GPIO_CLK, EVAL_COM3_RX_GPIO_CLK};
const uint16_t COM_TX_PIN[COMn] = {EVAL_COM1_TX_PIN, EVAL_COM2_TX_PIN, EVAL_COM3_TX_PIN};
const uint16_t COM_RX_PIN[COMn] = {EVAL_COM1_RX_PIN, EVAL_COM2_RX_PIN, EVAL_COM3_RX_PIN};
7) In stm32100b_eval.c -> In function STM_EVAL_COMInit ()
else
{
RCC_APB1PeriphClockCmd(COM_USART_CLK[COM], ENABLE);
}
And that is all I think this shoud work correct but it isn't...
Could somebody help me with this?
Greetings
