View Full Version : Need Help with PIC as SPI Slave

Dear Forum,
I have got to pick up data from an instrument with an SPI interface
The trouble is the Instrument acts as master
(providing the clock @ 100kHz)
Means I will have to run the PIC as slave.
Is there an (easy) way to achieve this in picbasic?
any input is appreciated!
regards

Is there really no one who can help?
I think the MSSP module is the one to use.
But I'm really struggling with it.
What registers are to be set and how do I set them?
And how do I sync to the incomming datastream?
Here some more details:
Incomming data is in bursts of two packets (four bytes each packet).
there is a delay of about 200µS between two packets of a burst
and there is a delay of about 200 ms between two bursts.
The clock idles HIGH
I'm planning to use a 16F876A @ 20MHz
Any code snippet or advise will be appreciated.

Thanks for "many" replies
I have found a solution to the problem on my very own!

Where did you find the solution? I might be running into the same type of scenario as yourself. I however have choice of interfaces to use.
