Hi,
I have experience on programming in C language PIC microcontrollers from 18F, and 16F famillies. I have also experience with MPLAB environment tool, and C18 compiller. In the applications that I previously developed, I used sensors, real time clock ICs, and timers. Likewise, I developed a card reader aplication, that used a rfid reader, there I had to implement a Wiegand 26 protocol, in order to read with the MCU the information that was previously read by the reader when the tag was put on it, and this information was displayed on the LCD.
