ATProgHead

Description

The ATmel Programming Head (ATProgHead) is used to program 28-pin and 8-pin Atmel (AVR) microprocessors.

Here is the ATProgHead installed on top of the GVSDuino (Rev X4 or higher) and a FTDI-USB-TTL card in a 3D printed case.

Features

ATProgHead board features include:

• Daughter card to the GVSDuino (Revision X4 or higher) and gets installed above the GVSDuino board
• Status LEDs
  • PROG - Programming in progress
  • ERR - Error while programming
• ALIV - Heartbeat
• On-board 16 MHz resonator
• Extended 12-pin ISP connector on bottom of board
• Separate 6-pin ISP header allows board to act as an ISP programmer
• The GVSDuino uses an FTDI-USB-TTL board for its USB host connection.
• ATProgHead supports ATMega328P, ATTiny85 and other Atmel AVR parts.
• Can be used to load bootloader onto factory fresh chips.
• Can be used to load sketches onto chips without the overhead of the bootloader.
• 28-pin ATMega328P socket has a Zero Insertion Force socket which allows for easier programming than standard sockets (no tools required).
• 8-pin DIP socket for ATTiny parts
• 100mm square form factor
• 4-40 mounting hardware
  • 3D printed standoffs for spacing off GVSDuino card

Compatible Software

• The board is compatible with ArduinoISP running on the GVSDuino.
  • Select Arduino as ISP in the Arduino IDE
• Details on programming ATTiny85 parts can be found here.
• Our ATProgHead ArduinoISP code is here (for our X1 board which had LED sense reversed).

Usage

• ATProgHead can be used to program the bootloader into new parts or program a sketch into a part.
• Compile your code and upload it.
• See uploading below for details.

Connectors

H1 - GVS Duino interconnect cable

The connector from the GVSDuino to the ATProgHead is:

H2 - ISP Cable Connector

The ISP Connector pinout is:

Board Dimensions

Revisions

Revision X2

Revisions X2 is in development.

• Corrects issues found in Revision X1 boards.
• Adds 6 pin ISP connector as H2.
• GVSDuino changed to move D10 from pin 5 to pin 7 and add RST where D10 was previously.
  • This allows GVSDuino to be programmed from the ISP connector and still support the ATProgHead adapter
    • Requires Rev X4 GVSDuino
