Suggestions for a PIC for a one time project.

wrote: I have a project I would like to build, and this would be for me a first time PIC controller project. I am looking for a PIC to do the following: 1. Address 17 parallel binary weighted bits (need at least 17 I/O's in addition to inputs from (2) below and outputs for LCD (3) below. 2. Have a keypad or rotary encoder to select combinations of the above bits. 3. An LCD display of a frequency generated by the PLL device attached to it per instructions below in (4). 4. Be able to enter a frequency such as 2300.6375 MHz, and do the math to subtract an IF frequency and divide the resultant frequency by some multiplier to address the parallel bits. The PIC should be available with an evaluation board containing an LCD display a keypad or rotary encoder. I do not want to have to design a circuit board for a one time project. For background, I have a Scientific Atlanta synthesizer that is designed to generate a frequency in the range of 100.2x to 110.7x MHz to phase lock a microwave brick oscillator used for a C band satellite up and downconvertor. The unit has an external BCD switch which is designed to display 3200.XX to 4200.XX MHz and I wish to re purpose it for a different frequency band. Any recommendations? |
