Status

The current version of AVR-Ada is V1.2 based on gcc-4.7.2.

The provided Ada run time system (RTS) is for the most part not even a run time system. It is more a compile time system :-). Most files in the RTS are only needed at compile time. As a consequence we only have limited support for exceptions and no tasking (multi-threading).

There is some AVR specific support. Type and interface definitions, timing routines, eeprom access, UART, and most importantly the necessary port and interrupt definitions for most AVR parts.

Some sample programs show how to use the compiler and the library. This includes the demo programs from the avr-libc distribution and some of Peter Fleury's example programs translated to Ada (these programs are from 2006 and need some updates).

The documentation consists only of the pages here in the Wiki. Feel free to ask any question on the mailing list.

Supported Devices

We distinguish between primary devices and supported devices. Primary devices are used by the developers of AVR-Ada. The sample programs and the library have been tested with primary devices only.

Primary Devices

atmega8 atmega168 atmega169 atmega32 atmega328p atmega644p atmega2560
attiny13 attiny4313 attiny85

Supported Devices

Supported devices only have a stripped down support library. If you want to use one of them, drop us a note on the mailing list and we make it a primary device. If your preferred device is not listed here, then also drop us a note and we shall include it.

Future Development

The next version will be AVR-Ada V2.0.0 . It will be based on gcc-9. The only primary device will be the ubiquituous atmega328p of Arduino fame. If we feel couragous, we might add the avrtiny85 and the atmega32usb to the primaries. I don't test on anything else.

later AVR-Ada versions

• Ada tagged types, interfaces, and dynamic dispatch
• Arduino package to access the general purpose IO pins using the Arduino naming scheme
