Hi,
I am having difficulty sendind a message from my 16F876a to SPI slave,

<PIC = Master> <SPI Device = Slave> I do not care what information Slave sends back,
I am using PIC Assembler.
I am using 8MHz XTAL
I initialize my PIC like this:see attachment

I am working off example from Microchip see attachment,
When i scope my CLK line of PIC I can not see it clocking the SPI at all.
So I believe i am missing something fundamental, or is PIC not able operate SPI at 8MHz atal, there is no indication of this in data sheet

Setting ADCON1 does not turn off analog functions. You also need to set the appropriate bits of CMCON. See the datasheet for the value of bits CM2:CM0 of CMCON.
 

after chacking data sheet i believe default value for CMCON is ok
