| ATMega128 |
| --------- |
| |
| This port of NuttX to the Amber Web Server from |
| `SoC Robotics <http://www.soc-robotics.com/index.htm>`__ is partially |
| completed. The Amber Web Server is based on an Microchip ATMega128. |
| |
| Atmega1284P |
| ----------- |
| |
| The Atmega1284P is a chip from Microchip ("inherited" from Atmel) with the |
| following features: |
| |
| - 16MHz 8bit AVR RISC Processor |
| - 128Kbyte Flash |
| - 16Kbyte RAM |
| - 4Kbyte EEPROM |
| - 2 High Speed Serial Ports |
| - 2 8-bit Timer/Counters |
| - 2 16-bit Timer/Counter |
| - 1 Master/Slave SPI |
| - 1 I2C controller (aka Two-Wire interface) |
| - 8Ch 10bit Analog Input port |
| - up to 32 GPIOs |
| - Watchdog timer |
| - Real Time Clock |
| - JTAG/OCD Interface |
| |
| AVR ATMega2560 |
| -------------- |
| |
| Extension of the AVR architecture to support the |
| ATMega2560 and specifi support for the Arduion MEGA2560 board were |
| contributed by Dimitry Kloper and first released in NuttX-7.14. |
