WIsp628 + 12F675 -> unable to "go" or erase - GUILLAUME SAUPIN - Jul 2 7:17:00 2004

Hello, I do not manage anymore to "go" or erase one of my 12F675 since I have configured the gp0 pin as an output. The chip still works, but there is no way to erase it, or read its content, ... I'm using a wisp628 (which work with another 12F675). Is there a way to erase or reprogram my 12F675, or must I send it to trash. And more important, can I configure the gp0 and gp1 (which are use by wisp628 ti proram the chip) pins as output ? Apparently, each time I configure these pins as output, I can't program the chip anymore. thanks guillaume saupin |

Guillaume, I use a Wisp628 at work to re-program a 12F675 product which has LED's on various outputs, it is potted so cannot remove the IC. The Wisp628 is used because it is the only programmer that works, our PicStart & Promate will not reprogram this product. To make the Wisp628 work I had to short out the 47R to the MCLR line Regards Ian > -----Original Message----- > From: GUILLAUME SAUPIN [mailto:] > Sent: 02 July 2004 13:18 > To: > Subject: [piclist] WIsp628 + 12F675 -> unable to "go" or erase > Hello, > > I do not manage anymore to "go" or erase one of my 12F675 since I have > configured the gp0 pin as an output. > The chip still works, but there is no way to erase it, or read its > content, ... > I'm using a wisp628 (which work with another 12F675). > > Is there a way to erase or reprogram my 12F675, or must I send it to > trash. > And more important, can I configure the gp0 and gp1 (which are use by > wisp628 ti proram the chip) pins as output ?

HI, Thanks you very much for your explanation. It works well : I've been able to flash my 12F675 without any problem. I'll avoid me to buy another chip .
