#88180 - Another variation Responding to: ???'s previous message |
A couple of years ago our production people needed to start programming AVR-based modules. I didn't want to give up my development board to them for this purpose, so I built an AT89C2051 based board very similar to Charles' schematics, but with DUAL SPI ports.
Two AVR boards would be plugged into it: a master that I programmed, and a board to be programmed. Push the button (a reset button) and the code within the 2051 would read the flash, eeprom and fuses of the master part, copy to the target, then verify. At the completion a go/no-go LED would be lit and the code would hang...waiting for the target to be replaced and the reset button pushed again. I've just finished implementing a similar sort of programmer, this one aimed at the AT89C51CC03. It takes a binary image of the target's code, converts it to Intel hex per Atmel's FLIP programming interface, and stuffs it to the target. Dennis |
