  1. Hi, guys. I am a beginner in Stellaris microcontroller programming. I try to generate a delay of 1 sec (1 sec - led ON, 1 sec - led OFF). I have selected the timer0A - 16 bits. Delay - 1sec. Frequency = 4 MHz T = 1 / 4Mhz = 250 nsec. So, to generate a delay of 1 sec : 1.000.000.000 nsec / 250 nsec = 4.000.000 4.000.000 = 62.500 * 64; But i think in my code i must set another bit, i dont know if it is correct, his name "main interrupt". Here is my code :
  2. Hi. I try to download a program in microcontroller and i receive the next error : CORTEX_M4_0: Trouble Reading Memory Block at 0x708 on Page 0 of Length 0x18: Debug Port error occurred. CORTEX_M4_0: Error: Debug Port error occurred. I use Tiva C Series LaunchPad EK - TM4C123XGL.
  3. Hi all. First of all i have made a program who blink a led. I use the interrupt of Timer0B interrupt. I enabled this interrupt with this instruction : IntEnable(INT_TIMER0B_BLIZZARD); This interrupt is defined in the header file hw_ints.h : #define INT_TIMER0B_BLIZZARD 36 // 16/32-Bit Timer 0B And program works very well. But now, i want to enable the same interrupt with another instruction : NVIC_EN1 = 0x00000010; In my program the Timer0B interrupt has number 36. in header file hw_nvic.h : #define NVIC_EN1 0xE000E104 // Interrupt 32-54 Set Enable
  4. Hi. I want to made a simple program who turn on/off a led. In the function below i must use the XOR operator in line : GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3, 8); How can i write the XOR operation ? void Timer0BIntHandler() { TimerIntClear(TIMER0_BASE, TIMER_TIMB_TIMEOUT); counter++; if(counter == NUMBER_OF_INTS) { GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3, 8); counter = 0; } }
  5. Hi. I have the next code : #include<stdint.h> #include<stdbool.h> #include"inc/hw_types.h" #include"inc/hw_memmap.h" #include"driverlib/sysctl.h" #include"driverlib/gpio.h" int main() { int LED = 4; SysCtlClockSet(SYSCTL_SYSDIV_10 | SYSCTL_USE_PLL | SYSCTL_XTAL_16MHZ | SYSCTL_OSC_MAIN); SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF); GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3); while(1) { GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3, LED); SysCtlDelay(2000000); { LED ^= 4; } } } In this code i have the n
