| 1 | Chiptest - The quick and dirty AVR tester.
|
|---|
| 2 | ==========================================
|
|---|
| 3 |
|
|---|
| 4 | So, you made a new project board using an AVR microcontroller, and you want to
|
|---|
| 5 | make sure it works before starting to develop your firmware. Debugging both
|
|---|
| 6 | software and hardware at the same time is a pain.
|
|---|
| 7 |
|
|---|
| 8 | Enters chiptest. This is a simple test program that makes sure the most basic
|
|---|
| 9 | stuff is working.
|
|---|
| 10 |
|
|---|
| 11 | Right now chiptest supports the following devices:
|
|---|
| 12 | * ATTiny2313.
|
|---|
| 13 |
|
|---|
| 14 | It tests the following features:
|
|---|
| 15 | * USART
|
|---|
| 16 | * Timers
|
|---|
| 17 | * One GPIO
|
|---|
| 18 |
|
|---|
| 19 | How to use it
|
|---|
| 20 | =============
|
|---|
| 21 |
|
|---|
| 22 | * Adjust the pinout at the top of main.c and the CPU clock in the makefile to
|
|---|
| 23 | your needs
|
|---|
| 24 | * Plug your usbasp and board
|
|---|
| 25 | * make flash
|
|---|
| 26 |
|
|---|
| 27 | How to tell if it works
|
|---|
| 28 | =======================
|
|---|
| 29 |
|
|---|
| 30 | If everything goes well:
|
|---|
| 31 | * The LED will blink at a well-known (but currently undocumented! sorry!) rate
|
|---|
| 32 | * The character 'H' is sent to the serial port in a loop.
