VPP w/ reset chip

[towlerg]

Sorry, never used that programmer so can't say. Nor am I aware of the downside of LVP (by default I turn off that fuse). I use PicKit2 which has the facility to use LVP, but I have never had occasion to use it.

what program do you use with the PicKit2 to program chips ?

i have a buddy who does this stuff in C and uses MPLAB programming environment to program the chips but it makes you compile every time to program the chip, it seems very unwieldy

re the MCP131 discovery
the data sheet is a bit of a puzzle, in one place it says -RST ABS MAX 13.5V apparently for the whole family on the data sheet, but in another place it says MCP121 only for 13.5V (the difference is '131 has internal pullup)

also in related literature it never shows the '131 for this attribute but always the '121
i have a support ticket at microchip, have never been real impressed with their replies so far but if i find something out i will report back here

I use the GUI based stand-alone, PICkit2V2.exe. It has the handy feature that monitors the .HEX file and if it's modified, will automatically program the PIC. Only downside is that some compilers delete the .HEX file before they try to compile, and of course if compilation fails they do not create a new one. I don't know if PICBasic does this but I know that Proton has a mechanism to avoid this situation.

If you want to use this program manually, it is not necessary to recompile, just select the .HEX and hit GO.
