I am sure anyone who has been around for at least a months has an idea of most of the projects on piclist.com. I was poking around serial IO and came across the PIC Dumb terminal and thought of it as a great project. I would like to have something that took rs232 from a pc and display it o

Hi, I have a project where I have a PI16F88 to communicate with a PC via RS232, and control a relay, and read an ADC. When I have the PIC kit 3 interface connected to my board and MPLAB is communicating with the PIC my code works fine. As soon as I disconnect the PIC kit 3 from my board, and reset the power the code stops running. I have a 1k resistor pulling MCLR to 5V, and a 0.1uF capacito...

I try to make an asynchronous serial communication between PIC16F628 and notebook USB port. I use USB-RS232 converter and MAX232 components between PIC and notebook. PIC can send data to notebook. It is OK. But when I try to send data from notebook to PIC, it is unsuccessfull. It runs with desktop computer. I think there is a problem between USB
