Has anyone any idea where I can get a double precision maths library which will work with the Keil C51 compiler.
Unfortunately the hardware was designed when I arrived on the scene so I have to make the best of a bad situation. However, there is not much choice available when one wants a single chip with 24 bit adc, SIO, PIO, I2C and on board programming built in. As far as $5000 for a library is concerned, it is possible to buy a complete development system with full double floating point 'C' compile for a lot less than this.
