2) Under Tools->Programmer USBtinyISP is selected. UPDATE: I managed to install AVRDude 6.0. 1) Under Tools->Board Menu Adafruit Trinket 8MHz is selected. Have I inadvertently skewed with the chip's fuse bits? How can I save this chip? This simply returned: avrdude: Error: Could not find USBtiny device ( 0x1781/0xc9f) The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. I then connected the device and sent: avrdude -c usbtiny -p atmega328p I can no longer however upload any further code to the chip, since I couldn't get AVRDude to work on my Mac, I installed AVRDude 5.1 on my Windows 8.1 PC. I didn't feel comfortable changing fuse bits I attempted to install the Arduino boot loader again through the Arduino IDE.Īt this point a number of errors were thrown but the board started to use it's external clock and run the Blink program correctly. I feel good about the circuit itself as I managed to upload the Arduino Blink sketch via the Sparkfun AVR Pocket Programmer.Īfter uploading this sketch I noted that the ATMega was using its internal oscillator. 51 in stock Adafruit Trinket - Mini Microcontroller - 3.3V Logic - MicroUSB Product ID: 1500 Add to Cart 6.95 In stock Adafruit ItsyBitsy 32u4 - 5V 16MHz Product ID: 3677 Add to Cart 9. I recently assembled an ATMega328P based micro-controller PCB of my own design.
