Motorized Fader

Description

Program for the ATtiny13A that controls a motorized fader by moving into a saved position read out of EEPROM memory.

Requirements

Hadware:

  • ATtiny13A/ATtiny45/ATtiny85.
  • usbasp programmer.
  • UNIX computer(to use the scripts for automation).

Software:

  • avr-gcc
  • avrdude(<=7.0)
  • CMAKE(<= 3.20)

Instructions(Windows)

Flashing the Project

On Windows(usbtinyisp)

  1. Install the usbtiny driver:
    1. plug in usbtiny device
    2. Install the drivers from: adafruit
  2. open Powershell
  3. navigate to the repo directory cd Downloads\gf_002
  4. enter the command below.
./avrdude.exe -p t13 -c usbtiny -B 125kHz -U flash:w:.\pre_built\attiny13_6-9Mhz.hex -U lfuse:w:0x6A:m -U hfuse:w:0xFF:m -U lock:w:0xFF:m

On Windows(usbASP)

  1. Install the usbasp driver:
    1. plug in usbasp device
    2. run the 'zadig-2.8.exe' program
    3. select the libusb 32 on the right by clicking the down arrow to select.
  2. open Powershell
  3. navigate to the repo directory cd Downloads\gf_002
  4. enter the command below.
./avrdude.exe -p t13 -c usbasp -B 125kHz -U flash:w:.\pre_built\attiny13_6-9Mhz.hex -U lfuse:w:0x6A:m -U hfuse:w:0xFF:m -U lock:w:0xFF:m

Instructions(UNIX)

Building Hex Files

Builds the binary hex files. They are located in the build/src/ directory found in the project root.

cd ./<PROJECTNAME>
echo "2" | ./otto.sh

Automated Flashing Hex Files

Builds then flashes the binary hex files onto the micro-controller

cd ./<PROJECTNAME>
echo "4" | ./otto.sh

Running Tests

The code below will run the cpputest tests in verbose and color mode.

cd ./<PROJECTNAME>
echo "1" | ./otto.sh
