Hi All PICers ! b> From: Mark Jurras b> Subject: Hobby vs Production Programmers (ON Topic!!) b> To: PICLIST@MITVMA.MIT.EDU b> b> In the past there has been discussion of Hobby type b> programmers that program and check the PIC at 5V only. b> Production programmers seem to check the Min and Max b> operating range. Is this check done during the blank check b> or during code verification or both? Hm. 1 If You work with flash 84 its enough only during verification, if your programmer send "Erase All" command before wriing. 2 If You work with JW part, I strongly reccommend to provide blank checking with low Vdd (or both low & high Vdd) and verification with low and high Vdd. 3 If You work with OTP devices you may assume that it is clear, and provide only verification with low/high Vdd. ------------------------------------------------------------- Best Wishes, Alex Torres.
