I did not say PBP have high level commands to drive your specific device using the MSSP module - no - I said you don't need any assembly language to use the MSSP module.

You configure the module by writing values to a couple of registers. (Should it run in SPI or I2C mode, what clock frequency, MSB/LSB first and so on). It's the same procedure as configuring an I/O for the correct mode by setting TRIS and ANSEL or to select what clock source to use for the ADC by writing to ADCONx (or whatever). But if you're not prepared to read a couple of pages in the datasheet then forget it and stick with SHIFTOUT.

Sometimes users seems to think that TRIS, CMCON, ANSEL, ADCON and what not are commands - they are not. They are registers in the PIC to which can write by simply assigning a value to them, TRISA=127 or read myVar = CMCON. That's as basic as it gets and doing that to a few registers are all it takes to configure the MSSP module. Sending a byte is then as simple as writing said byte to another registers and out it goes. Again, just take 1h and READ the datasheet.
