    I can't program STM32F100RBTx to send pwm signals

    I am trying to send PWM signals using STM32F100RBTx but it do not working. I double checked all the address but it is still the same. I wasn't sure if I was flashing at the begging but I configured the PB7 pin to be GPIO output and connected to a led and the led is working so I can flash it and...

    PIC16F676 PORTA doesn't work as intended.

    There is a simple project I want to build which consists of five buttons and five leds, two of the buttons that I want to stick to PORTA, require pullups to work as they share a common ground while the rest of the three buttons on PORTC doesn't need pullups. The problem that I am facing is that...

    How to write an embedded C program for adding two numbers stored in memory locations

    Can use a pointer to access content of the memory location on embedded c. I need to write a program that add two numbers stored in memory location. int *p; int *q; p = (int*) 0x30610000; q = (int*) 0x30610004; int sum=(*p)+(*q) Is the above code correct? I need understand how access a content...

    Embedded Derivative Control for DC motor speed

    Hi all, I am fairly new to embedded control systems, for which I am using a PSoC 5LP to implement closed-loop speed control. I am currently working out the code for the PID controller and this is the following code I have (in C): P = Kp*error; I +=ki*error; D=Kd(error-last); PID=P+I+D; Now, I...
