Working with a PIC microcontroller

As some of you probarly know iam currently doing a bachelor of electronics.

One of my current projects iam working on at school is developing a wireless connection from the schools roof to the techopark (3 floors lower).
The goal is to send 4 analog signals to the technopark. For this we made a design of a PCB that uses a FM radio signal at 433MHz to transmit all this data.
Sounds easy, isnt it?
No, it isnt. Firstly we had the basic problem to design the PCB. This wasnt that difficult at all. Just a few zener diode’s and it works (Probarly?)

After this we needed to choose what PIC we wanted to use and what pre made receiver and transmittor. This took some time but we found good things.

The problem we are currently having is to actually program our PIC. Hopefully the just ordered programmer arrives pretty soon so we can finish this project on time 🙁

  1. Hi I really thankful to you because you are simply great. I am very happy to post my comment in this blog. I gathered lot of information from this site. Later model PICs feature an ICD (in-circuit debugging) interface, built into the CPU core. ICD debuggers (MPLAB ICD2 and other third party) can communicate with this interface using three lines. This cheap and simple debugging system comes at a price however, namely limited breakpoint count (1 on older pics 3 on newer PICs), loss of some IO (with the exception of some surface mount 44-pin PICs which have dedicated lines for debugging) and loss of some features of the chip. For small PICs, where the loss of IO caused by this method would be unacceptable, special headers are made which are fitted with PICs that have extra pins specifically for debugging.Nice blog.
