|
** ChibiOS/RT port for Atmel AVR ATmega1280. **
|
||
|
|
*****************************************************************************
|
||
|
|
|
||
|
|
** TARGET **
|
||
|
|
|
||
|
|
The demo runs on an Arduino Mega board.
|
||
|
|
|
||
|
|
** The Demo **
|
||
|
|
|
||
|
|
This demo uses ICP3 (ICU3 input) which is located on pin PE7 to measure signal
|
||
|
|
width and period. The signal is output on pin PD4 using standard PAL calls and
|
||
|
|
thread sleep functions. PD4 must be wired to PE7. It outputs three different
|
||
|
|
waveforms with aproximately 1s duration using 50%, 25% and 75% respective duty
|
||
|
|
cycles. After that it just turns on ICU3 and waits for it to overflow. The values
|
||
|
|
read on each of these operations is output to SERIAL1.
|
||
|
|
|
||
|
|
** Build Procedure **
|
||
|
|
|
||
|
|
The demo was built using the GCC AVR toolchain. It should build with WinAVR too!
|
||
|
|
|
||
|
|
** Notes **
|
||
|
|
|
||
|
|
This demo runs natively so the Arduino bootloader must be removed and the FUSEs
|
||
|
|
reprogrammed. The values used for fuses are LFUSE=0xe7 and HFUSE=0x99.
