Make sunre that microcontroller pins are configured as digital, not analog. Most PIC micros have analog inputs on some port, which are set to be analog by default (one of the things I don't like about PCU MCU's)
i also need help... i want to communicate, serial camera to mcu and data will be save to sd card... someone please send me a circuit connection of my project... im using pic18f4550 mcu, and the source of my serial camera is 3.3v... some one help me...
Do we have to read the Echo pin as Digital? or is it Analogue? @ Tahmid, I find ur post very helpful.
@dselec - The answer to ur first question is Yes.. but the camera is not part of our project.
thanks guys. I'll post if there's an improvement.
