i'm afraid that the time gained in the calculations or analog reads will be lost in the communication time with the 328 chip.
Does anyone used the micromega um-FPU v3.1 or 64 (http://micromegacorp.com/products.html), if yes how fast do you get the results form it to arduino (i want to use I2C)?I'm thinking to use it because it has fast 12bit ADC and also to make floating point calculations (for gps, motors and others)but i'm afraid that the time gained in the calculations or analog reads will be lost in the communication time with the 328 chip.Thank you
I did read the posts from this forum but none answered may questions.
I can't use SPI because i don't have enough pins to use so i will need to use I2C.
If that chip can't do better than 600mS for anything it has no point in life
