The latest Version 3.4 of uLisp for AVR now supports Microchip’s Curiosity Nano boards for the AVR128DA48 and AVR128DB48. These take the AVR architecture to a new level, with clock speeds of 24 MHz, 128 Kbytes of flash, 16 Kbytes of RAM, a DAC, and 12-bit analogue inputs.
uLisp 3.4 still supports the earlier AVR platforms, down to the Arduino Uno. On all platforms it now supports keywords as a more convenient way of specifying options in Arduino functions, such as :input-pullup in pinmode , and there are several other minor improvements and bug fixes.
