LGT8FX8P ISP programmer using FT232R in bitbanging mode.
ATTENTION: this is not a working version; try it at your own risk.
When the test program (HEX format) flashed with the bootloader or the LGTISP here's the result:
When converted to BIN and flashed with the FT232R here's the result:
The PB5 LED blinks as expected in the two cases.
Can some one, please, geuss what's going wrong in the 2nd case (using FT232R)?
Usage:
1- compile this program using mingw, dont' forget ftd2xx.lib and ftd2xx.h
you get : lgtdude.exe
2- build then convert your LGT program to flat binary format using avr-objcopy:
avr-objcopy -I ihex -O binary myprog.hex myprog.bin
3-run lgtdude
lgtdude.exe myprog.bin
NOTE:
TX ==> clk
RX ==> reset
DTR ==> data
PLEASE: if you can help drop a word to malaouar67@gmail.com
