i have a good idea and i am working on it :-) you take an f84 and tell it a command then 16 bits of data to clock to the pic or something like that. still thinking about how it should work. andy ----- Original Message ----- From: "Carlos Nieves Snega" To: Sent: Friday, May 25, 2001 6:00 AM Subject: [PIC]: Universal programmer > Hi all, > I'm thinking in a design for an universal programmer, controlled by a PIC. > I'm a bit tired to search for a programmer for every device I plan to use, so I would want to build one able to program all devices. > My thought is that it will be "open hardware" (i.e. you will be allowed to use, build, and improve it at your own, like open-source software) with an open source > software. > I will make the software to program the devices I'm using, but other people working with other devices can do the same... so in some time we could have a free > universal programmer. > I have one design in mind, with 50 pins to interface with the device.
