So their websites are updated with new informations. V170 Classic from Microchip supports 16F627A/16F628A /16F648A. I have tested the last two chips with no problem. It is supposed to support 16F913/914/ 16F877A as well. But so fat I have no success with 16F877A yet. Mark Rages' program under Linux does not support the 18pin 16F627/628A/629A now. Both program are open source so one can actually add more supports for more chips within the limitation of the firmware (quite a lot of empty space now but nobody likes to work with the 16C745). Actually no special adapter is necessary since you only need ICSP. What you need is soldering 5 wires (almost zero costs) from J3 and link them to your board or the correct pins of your ZIF sockets. The so-called adpater is just doing this for you.

Subject: Re: [PIC] I2C development tool for PC ... And a few more that "require an adapter". As the website also states the PICkit1 is meant for 8/14-pin devices, and some of the device you list (and especially the 16F628A, which I am most interested in) have 18-pins, I was wondering how I should envision this. I would imagine it has something do do with the "in circuit programming" or the adapter... Could you please explain? Would it involve parts above and beyond the $36 that the kit costs? Is there a reason why the 16F88 would not be in the list? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
