Electronics production
This week I made my first programmer.
1/64, 1/32 drill bit milling
below: remaining copper plate, used worn out drill bit
above: clean cut, using new drill bit
Sanded board, cleaned with alchohol
All parts to assemble
Solder finish
USB head attached
Plugin USBtiny to Linux computer at Harvard Shop
Commend line inputs:
First attempt, Fail
Run make flash
fab@fab-Rikku:~/Desktop/fts_firmware_bdm_v1$ make flash
avrdude -p attiny45 -c usbtiny -P usb -e \
-U flash:w:fts_firmware.hex
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
avrdude done. Thank you.
Makefile:61: recipe for target 'flash' failed
make: *** [flash] Error 1
Second attempt, Sucess
Run make flash
fab@fab-Rikku:~/Desktop/fts_firmware_bdm_v1$ make flash
avrdude -p attiny45 -c usbtiny -P usb -e \
-U flash:w:fts_firmware.hex
