![]() In programmers for those chips programer quality is an importent factor. Those chips had specific voltages to apply and pulsewidths (Very old were 24V or 25V, newer versions were around 12.5V). ![]() (Such as 27c128, 27c256, or any number starting with "27" and ending with a round power of2). A "programmer" is nothing more than some communication channel between a (usually) PC and the target to exchange data, and commands.Ĭompare this with for example old Eproms. I also se no reason to not trust something like Ponyprog.Įven old chips such as at90s8515 effectively program themselves. ![]() If you have a beaglebone, Raspi, Cubie board or another small Linux board with GPIO pins, then AVRdude can program your at90s8515 with it. If you have an old PC with an LPT port, then avrdude can program your at90S8515 with it. Programming stuff into flash has inherent delays.ĪVRdude can control a lot of different hardware. More modern AVR's have small pages, you load 8 bytes into some (invisible?) buffer, and then program those 8 bytes into flash. And I believe AT90S8515 is inherently slow because it programs 1 byte at a time. ![]() It uses an at90s2313 to translate between RS232 and ISP. AN910 is probably the second AVR programmer I used.įirst was Pony Prog (or similar, and only once) to program AN910.ĪN910 is an Atmel application note (& software) to build your own programmer.
