FYI uM-FPU64

Hi All,

The uM-FPU has many features and is useful in simplifying complex projects. Especially when you want speed and precision in harmony, significant processing can be offloaded from the Prop by using an FPU with user defined functions .

The 64 bit version has expanded digital I/O and ADC capabilities, foreground/background processing. It is said to be compatible with the instruction set of uM-FPU 3.1, but internal EEPROM seems to be missing in the released product.

After I receive a DIP-28 FPU64, I will upgrade the SPI and I2C drivers for the new chip in OBEX.

Cheers,

Istvan

    They are obviously using a 16-bit Microchip dsPIC, probably the dsPIC33FJ32GP302:

    Most of the functionality is provided by the Microchip libraries supplied with the C30 compiler.

    2 um-FPU64 DIP28 chips arrived today.

    Leon:
    For me that is not so obvious. If it is so, then there should be a fine piece of code inside. Thanks for the info.

    Cheers,

    As I mentioned, they are probably using the free Microchip libraries for most of it. They are written in assembler and are very efficient.
