So I am looking at incorporating the SX48 into a system, primarily because it has counters.
 

The only problem, is when I am reading the manual, I honestly cannot understand what it is talking about in capture/compare mode.

 

I feel bad, but for the life of me, I can't tell what's going on and I was wondering if somebody could help explain it to me.

 

Each timer has the following pins:

    capture input 1

    capture input 2

    pwm/compare output

    external event counter input.

 

Each timer has the following registers:

    TxCPL

    TxCPH

    TxR2CML

    TxR2CMH

    TxR1CML

    TxR1CMH

    TxCNTB

    TxCNTA

 

Now.  I was under the impression that the Capture/Compare timer method could be used to capture analog values and be a 'rough' ADC.

 

The manual says a lot of things such as setting rising/falling edges on pins and comparing it to R2 and R1 registers.

 

Unfortunately, I am not able to connect what the manual says to how to actually implement it.

 

Is there anybody who can explain how to implement the counters in an ADC 'Capture/compare' type setting?

 

Thanks

Shaun
