[SOLVED] STM32 and Program trouble

[mekitron]

Hello All,

I am practicing on STM32 development board these days. I have written a piece of code which prints some lines on LCD connected with board. Board has ARM Cortex M3 Processor. Now, I want that what code I coded should blink on LCD. I know it is possible with timer programming but I can't find any solution. I am posting my code if you have some code like this please share with some explanation or help me that how I can do this.

#include <stm32f10x_lib.h>
#include "sys.h"
#include "usart.h"		
#include "delay.h"	
#include "led.h" 
#include "key.h"
#include "exti.h"
#include "wdg.h"
#include "timer.h"
#include "lcd.h"

int main(void)
{	
	u8 x=0;			 	  
  	Stm32_Clock_Init(9);
	delay_init(72);		
	uart_init(72,9600); 
	LED_Init();
 	LCD_Init();

	POINT_COLOR=RED; 		   
	while(1) 
	{		 
									 
		POINT_COLOR=RED;	  
		LCD_ShowString(30,50,"Mini STM32 Program ^_^");	
		LCD_ShowString(30,70,"It's Meki");	
		LCD_ShowString(30,90,"Help Me to blink these lines");
		LCD_ShowString(30,110,"Thank you");	    					 
	    x++;
		if(x==12)x=0;
		LED0=!LED0;					 
		delay_ms(5000);	
	}											    
}

I'll be thankful for your help in this concern.
Regards,
Meki

Your code looks good. Are you using led0 in your code for clearing the LCD ?
Please upload your circuit.

Hi,

STM32 is a higher end micro-controller and must need to initialize every IO pin which is used in project for working as input or output. Please read reference manual of micro-controller for detail IO configuration.
Every module in STM32 need clock frequency this include IO port also.

So please first read datasheet and reference manual carefully. This is not work like 8051.

Regards,

Thanks guys, I have done it.
