My problem is i need to send report by next week. So i dont have much time for make new servo controller. If i have more time i will wor with PIC that have internal UART like PIC16F877 or PIC16F628 What actually i want to do is to develop one system that can detect and lock onto moving object. This ...

Thank Sambuchi for your great help. I also hope only among this three cause this problem but bad .hex file---> i have compile many .asm to .hex, using more than one programmer yet still doesnt work or bad PIC---> I have 7 new PIC from microchip so must not bad PIC or bad crystal---> actually i have ...

Did you mean this step? You should now be able to type into the terminal program and see the characters appear as you type. Try moving the link from pins 1 to 5 and placing it from 1 to 14 and type a few characters. You shouldn't get any characters displayed as the serial port is buffering them beca...

Testing You will need a 9V dc power supply with a 2.5mm power plug, centre positive and a serial cable to connect the controller to your computer. You will also need a serial communications (sometimes called a 'Terminal') program. I used 'HyperTerminal' as it comes with Windows. First, without the ...

Servo operate correctly. Yes im using proper baudrate(oscillator 4MHz) Yes this project using hardware control. Yes my cable setup for transmit and receive. No setup to "echo" commands. Yes all ground is ground together. 4 wires are connected to serial port on both ends. my circuit schematic: http:/...

Thank for replying. Terminal program that i use is the one that come with windows xp (Hyperterminal). My setting is 2400 baudrate, 8 data bits, parity none, stop bit 1, hardware flow control. When connect the power, the PIC will send a message to the computer, which should come up in the terminal wi...

HELP - PIC16F84A Based Serial Port Servo Controller

Hello to all, i have asking many electronic community site yet i still cant solve my problem. Since this board about servo so i will try my luck here. Here the situation: I have build PIC servo controller by following all instruction at this site: http://www.digitalnemesis.com/info/projects/picservo...
