Post by thread:warp-13.

Hey all, I'm trying to program the 16F627 through MPLAB with my warp-13. It keeps giving me a failure message and I don't think it programs the bits or the code. Any ideas? Thanks, Aaron -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu

For AAron You create you hex file in MPLAB, exit MPLAB, open WARP-13, call up your hex file and program it. You must have the WARP-13 software. Sid -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

Apoligies to the group should have read the manual first. :) Apparently there's a bug with the 'F627 and the warp-13 you have to pull pin 10 low. I didn't find anything in the archives, so now it's there. :) Alittle "fix" and everything is ok! :) Aaron -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam.....mitvma.mit.edu

Check the Microchip errata sheet for this part, on the web site. It is shipped with the low voltage programming (LVP) bit set, and normal high voltage programming (thro /MCLR) will not override it. RB4 the LVP pin must be isolated (eg with plastic sleeve) on first programming, with config set fo LVP off. In theory it can then be normally programmed with the usual 13V on /MCLR and RB4 should default to normal i/o pin. I found that even after successfully programming the part in this way I still needed to isolate RB4 subsequently. Ken {Original Message removed}

RB4 the LVP pin No, definitely is not like in practice. I never had problems with HVP programming on 16F628, if the configuration word is right that one you choose it for de-activating LVP. So there is no relation between LVP pin and the first HVP programming. But LVP pin must be tied to GND through a 4k7...10K after a LVP to avoid pic malfunction. LVP is an anachronical function for this small PIC. Except programming feature directly from PC, it kills important hw resources. I dislike it. best, Vasile > must be isolated (eg with plastic sleeve) on first programming, with config > set fo LVP off.

Hello all, I'm wodering if anyones tried writing an 24LC64 eeprom with the warp-13. So far I use the DE command and start at org 0, but it puts nulls between each character in the eeprom. What methods are used to write eeprom data into hex files? Thanks, Aaron -- http://www.piclist.com#nomail Going offline?
