My recommendation would be to purchase one from Microengineering Labs www.melabs.com they have their U2 USB programmer for around $95.00 USD. Unless you just want to make your own, which would cost as much or more whe= n one factors in the time and cost of components, I would recommend buying on= e that is known to work. =20 Also, there is a complete development system from MikroElektronica. I have their EasyPIC 6 system which is awesome and it cost around $140.00 USD and includes a built in USB programmer, among MANY other features. MikroElektronika has a new development system available which has a few added features over the EasyPIC 6 and it is around $149.00 USD. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of saniye tokel Sent: Sunday, December 04, 2011 3:12 PM To: piclist@mit.edu Subject: FW: [PIC] From: sanietokel@hotmail.com To: piclist@mit.edu Subject: [PIC] Date: Sun, 20 Nov 2011 19:52:08 +0200 [We have a project and we are trying to make a pic programmer.We want to learn how can we use usb port, how can we connect usb and pic and how can communicate pic and usb?] --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
