ATTiny1634 Writing

For upgrading an Arduino so that it can program another microcontroller

AVRDUDE and AVR-gcc

Follow instructions here:

Tried to upload blink to Arduino Uno and got this error

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x58

Had to remove all wires going to Arduino ports and unplug usb before it would upload

Pin layout Arduino to ATtiny1634

Map of controller pins in on the microcontroller

Burning ATtiny1634

Load up ArduinoISP (in the Arduino IDE examples) onto the programmer Arduino

Download C code for ATtiny from here:

https://github.com/FYNCH-BIO/evolver-arduino/tree/master/ATtiny1634

On the terminal

Navigate to the folder containing ATtiny code (lightsense.c)

Run commands:

avr-gcc -g -Os -mmcu=attiny1634 -c lightsense.c avr-gcc -g -mmcu=attiny1634 -o lightsense.elf lightsense.o avr-objcopy -j .text -j .data -O ihex lightsense.elf lightsense.hex avrdude -p t1634 -P <Your Arduino Port> -c arduino -b 19200 -U flash:w:lightsense.hex -v -v -v -v

From <https://github.com/FYNCH-BIO/evolver-arduino/tree/master/ATtiny1634>

Replace <Your Arduino Port> with the port used by your Arduino (found in IDE under Tools>Port)

avrdude -p t1634 -P COM9 -c arduino -b 19200 -U flash:w:lightsense.hex -v -v -v -v

avr-gcc -g -Os -mmcu=attiny1634 -c LEDblink.c avr-gcc -g -mmcu=attiny1634 -o LEDblink.elf LEDblink.o avr-objcopy -j .text -j .data -O ihex LEDblink.elf LEDblink.hex avrdude -p t1634 -P COM9 -c arduino -b 19200 -U flash:w:LEDblink.hex -v -v -v -v
