Hi everyone,
I searched at the Microchip's web side but I didn't manage to find the pic that I want. So I am asking if there is any PIC that makes the analog to digital conversion of 8 channels at most at 20usec all of them and can achieve 230400 baud rate of the usart. |

I am sure there are many that will fit the criteria. The PIC24FJ64GA002 and related family members are one example. These PICs feature an A/D capable of sampling at 500Ksps (2us per sample). In addition you can automate the process. Basically you establish a mask of the A/D inputs you want sampled and start the conversion process. The PIC will sample all channels as identified in the mask and store each value in registers dedicated for this function. _________________ Regards, Andrew

Sorry for my mistake. I forgot to mention that I want to be 8-bit. Have you something in your mind? |
