multiprogrammer v9 osc
multiprogrammer v9 osc
Hello I am a newb to pic programming. The old version of the board had a switch to change from external rc osc fast/slow.This board does not so I am unsure how to set this up. also j18 and j19, what does the a6&a7 setting do

Re: multiprogrammer v9 osc
Hello,
The Jumper J18/19 switches the pin assignments for the oscillator pins. Most of the newer PIC devices such as the 16F1937 have optional I/O pins (A6&A7) that can be used if your not using the external oscillator source.
So you can either use the crystal for high speed reliable frequency operation.
Or you can use the internal oscillator which will vary slightly with temperature and pressure but gives you two additional I/O pins.
