About PIC selection, I've found 18f26k22 as an interesting candidate: - 64KB memory - 2 * USART - I2C *and* SPI (2 * MSSP) - independant analog pins, easier to map pins - clock up to 64MHz, 16MIPS - 3 external interupts - 2 * PWM output but not in production... Little brother 18f25k22 can be sampled, but "only" have 32KB memory. I'll try this one I guess. On the other side of the nest, Arduino provides: - 1 USART - 2 external interupts - SPI - I2C within ADC pins - 6 PWM channels (this can't be defeated...) This can be cuckooed by 18f25k22 :) http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en546240 Cheers (Groeten) Seb > > On Jul 5, 4:29 pm, Sebastien Lelong <[email protected]> > wrote: > > Hi guys, > > > > The Cuckoos are a bird family, known to be brood parasite.
