I've had plenty of success programming the 16F84A with my extremely cheap Olimex PG2C programmer. However, before I start to program my 16F628, I noticed that IC-Prog tells me to pull RA4 to ground.
My first question is simply, how the hell do I do that? If my programmer runs on power from the COM port of my computer, does this mean that I need to rewire my programmer so that RA4 goes straight to the ground of my comp port?
Secondly, is this absolutely necessary? I read that the chip will go into low voltage programming mode if this is not selected, and the JDM programmer option for IS-Prog will not work. Is there any software that will allow me to program the 16F628 without making such a modifcation?
Thanks for your help, and I'm sorry for being so ignorant.
