I'm thinking about using the Data EEPROM in an 18F8620, and can't figure out what the datasheet is trying to say. I hope someone can clarify. Section 7.8 says, in part "Frequently changing values will typically be updated more often than specification D124. If this is not the case, an array refresh must be performed. For this reason, variables

Has anyone successfully sent Fosc/4 to RA6 when using the internal RC oscillator at 8 MHz? I have tried a lot of combinations of Fosc and _CONFIG1 but so far, no output. I thought I did a pretty good job of reading the datasheet but still, no output; I must have missed something.

Has anyone used PicBasic Pro by MeLabs) and MBasic Pro (by Basic Micro)? How do the two compare? I can afford to get one or the other, and obviously want the better of the two products. By better, I mean easier to use, value for the money, more powerful. Please do not bother listing all of the other available Basic compilers. I have compared and contrasted

I've successfully used a bootloader in combination with an FTDI 232BM USB chip for simple serial communication to the PC, but I have a few questions about how best to power it. The application in question is battery powered, so I want to conserve as much as possible. Can I power the PIC off the battery, and use the power rail coming from the USB port w

I'm working on a project using the new 12F683 PIC and discovered that I need to upgrade my trusty Warp 13a programmer. Presently I'm at Redback 11 with a 4 Mhz resonator. Do I just program the bluepole hex file to a new PIC18F252 with my present setup then make the mods to the programmer (20 Mhz res, .1uF bypass caps at the socket)? Would appreciate
