Fixing the lack of a DTR pin on the Raspberry Pi for the purposes of uploading hex files to the arduino

Using avrdude with the Raspberry Pi

Since the Raspberry Pi lacks a DTR pin that makes it oh-so-easy to upload your hex files into the avr, we need this hack to make it just as easy. When you wire up your atmega chip, be sure to connect one of the digital gpio pins to the reset pin, and then you'll be able to use avrdude as if your serial cable actually had a dtr pin.

Instructions:

sudo apt-get install strace sudo apt-get install curl

• Install arduino-cli

curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh

• Add 'bin' created directory to your PATH,

nano ~/.bashrc export PATH=$PATH:/home/pi/bin

• Initialize arduino-cli

arduino-cli config init arduino-cli core update-index

• install board support

arduino-cli core install arduino:avr

• install avrdude trick

cp autoreset /usr/bin cp avrdude-autoreset /usr/bin sudo mv ~/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude ~/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude-original sudo ln -s ~/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude-original /usr/bin/avrdude-original sudo ln -s /usr/bin/avrdude-autoreset ~/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude

• install Hat source code and dep

cd project git clone https://github.com/btrinite/robocars_hat.git mv robocars_hat RobocarsHat arduino-cli lib install PololuLedStrip

cd ~/Arduino/libraries/ git clone https://github.com/PaulStoffregen/PWMServo git clone https://github.com/ElectricRCAircraftGuy/eRCaGuy_TimerCounter.git

• compile

arduino-cli compile -b arduino:avr:mini /home/btrinite/projects/RobocarsHat/

• upload sketch

arduino-cli upload -p /dev/ttyTHS1 --fqbn arduino:avr:mini /home/btrinite/projects/RobocarsHat/
