News - What to do when you screw…
about 6 years ago
I thought I would share here how I re-flashed my microview. Here are some pictures of my re-flashing setup. Upgrade microview firmware pics. It's relatively easy to re-flash if you have access to a programmer.
After removing the lens lift us the display and locate the via's labeled 11,12,13. These need to be routed as follows:
TP:13 -> SCK -> ISP Pin 3
TP:12 -> MISO -> ISP Pin 1
TP:11 -> MOSI -> ISP Pin 4
Then on the external pins
5V -> VCC -> ISP Pin 2
Gnd -> Gnd -> ISP Pin 6
Rst -> Reset-> ISP Pin 5
For my avrispmkii the following avrdude command line worked:
avrdude -P usb -b 19200 -c avrispmkii -p m328p -v -e -U flash:w:MicroView_combined_8-19-14.hex -U lock:w:0x0F:m
With the firmware from MicroView Firmware.
Your mileage may vary but hopefully this helps someone.
No public wish lists :(
