Post by thread:16f84 programmer

does anyone know of a cheap and good homemade programmer schematic? Thanks Ben Hamlett

The PROPIC from Octavio Nogueira is a very nice multi-purpose PIC programmer with software. http://www.geocities.com/SiliconValley/Pines/6902/ Ben Hamlett wrote: > does anyone know of a cheap and good homemade programmer schematic? > > Thanks > Ben Hamlett -- Joost de Vlieger spam_OUTde.VliegerTakeThisOuTnet.hcc.nl

David Tail has an excellent page with (among other things) lots of links to programmers (http://www.man.ac.uk/~mbhstdj/piclinks.htm). My own design (http://www.xs4all.nl/~wf/wouter/pic/wisp) is good, but much cheaper designs exist. regards, Wouter. ---------- > From: Ben Hamlett <.....asdfgKILLspam@spam@NORTHRIM.NET> > To: PICLISTKILLspamMITVMA.MIT.EDU > Subject: 16f84 programmer > Date: Sunday, July 05, 1998 23:49 > > does anyone know of a cheap and good homemade programmer schematic? > > Thanks > Ben Hamlett

Ben We use the 'Ludipipo' serial programmer - it's very simple and may be interest. Let me know if you need a PCB layout. .-. / \ .-. .-. / \ / \ .-. _ .-. / \ -/- Dr Sandra I.

It assumes that the high level voltage coming out of the serial port will be at least 12 volts. With different software, it could also program the PIC16F84 and perhaps the 8-pin PIC12 series.

Note: No power supply is required; nor a double-sided circuit board; and we're not selling anything. The resistor values are not critical. Instead of 2.2k, 2.2k, 10k, 22k, I have used 1.4k, 1.4k, 10k, 16k. The original plan had a 100-uF capacitor which I replaced with a 10-uF tantalum. There's not much to install, not much to solder. Be sure to get the diode and the capacitor installed the right way around. - Ludwig -----Original Message----- From: Ben Hamlett [asdfgspam_OUTNORTHRIM.NET] Sent: 05 July 1998 22:50 To: @spam@PICLISTKILLspamMITVMA.MIT.EDU Subject: 16f84 programmer does anyone know of a cheap and good homemade programmer schematic?
