    RS232 to max232 to PIC16F628

    pic 16f628 rs232 Thanks for your advice. I have been using assembly and I think the issue is how to write the code for the 4 bytes I want to implement. That is the tricky part for me. Rgds Jacksdums

    RS232 to max232 to PIC16F628

    pic16f628 rs232 Good friends I want to send 4 bytes to the PIC16F628 microcontroller and then the PIC should control the DC motor.The second byte is address, the third byte will have speed and directional bit and fourth is for error detection. The first is 8 bit (all ones as it is a preamble)...

    Circuits design help - three circuits, need explanation

    Circuits design help Hey Guys I am planning to design three circuits and not sure how I will do it. The idea is to get a packet probably 8bit fed to a PIC16F628. 1. A circuit that can generate a packet 2. Circuit to convert this packet to 1 and 0s (digital) 3. Gets fed to Shift register...

    Easy PIC PWM DC motor - getting a 50% duty cycle

    Easy PIC PWM DC motor Hey Guys I am having problems for 2 weeks now. I am trying to get a PWM signal.I am having issues programming my PIC16F627. The deal is its a 4 bit PWM which needs to be simulated on a mplab simulator(will build later the circuit). I am simply getting a 50% duty cycle. I...
