Does anyone know why Gpiox_Moder register cannot be updated?.
I am currently using Clicker 2 for STM32f407VG program using CodeGrip debugger.
Attach here are the code:
sbit Led1 at GPIOE_ODR.B12; //Set Led1 as Output bit12 GPIOE register
sbit Led2 at GPIOE_ODR.B15; //Set Led2 as Output bit15 GPIOE register
sbit PB1 at GPIOE_IDR.B0; //Set Pushbutton1 as Input bit0 GPIOE register
sbit PB2 at GPIOA_IDR.B10; //Set Pushbutton2 as Input bit10 GPIOA register
//Main
void main() {
//Initialized Pin
GPIOA_MODER |= 0x00000000; //Set all GPIOA to Input
GPIOE_MODER = 0x41000000; //Set GPIOE <15:12> to Output & GPIOE <0> to Input
Led1 = 0; //Set GPIOE12 to LOW
Led2 = 0; //Set GPIOE15 to LOW
while(1){ //loop
if (PB1 == 0){
Delay_ms(100); //Debounce for 100msec
Led1 = 1; //Set GPIOE12 TO HIGH
Delay_ms(250); //Delay for 250msec
Led1 = ~led1; //toggle GPIOE
}
if (PB2 == 0){
Delay_ms(100); //Debounce for 100msec
Led2 = 1; //Set GPIOE15 to HIGH
Delay_ms(250); //Delay for 250msec
Led2 = ~led2; //toggle GPIOE
}
}
Running Debugger simulation does Update or changes the GPIOE_Moder register.
However using Debugger Hardware shown no changes from reset state!
Using bulit-In GPIO library has no problem though.
