PIC SPI interface with Zigbee MRF24J40MA

[J_GROUP]

Dear Friends,

I trying to interface PIC 18F25k20 with zigbee module MRF24J40MA to tranfer an Ascii string but still no result.

Can you help me sample CCS code

Thank you

Look in the code library. Fully translated driver sitting there.

Sure hope you've got a 3V PIC connected to your Zigbee module.....
poof.....Zigbee don't like 5 volts for long....

Yes, I use 3.3 volt power supply.
I tried some code at code library but still no result.

You need to take fifteen steps back, and do some basic debugging....

Is your chip running, and running at the right speed - basic 'flash an LED' test?.
Then check your connections. Remember SDO on the PIC, is SDI on the device. The driver requires the hardware SPI connections, so on your PIC SDO is C5, SDI is C4, SCK is C3. As written the driver uses B1 for the chip select (note B1, not B0). Remember you need the fuse NOPBADEN, or port B wakes up set as analog, so the select line won't work.
Also disable the comparators.

You need to check that each line you use is operating normally, and will handle normal I/O.

One step at a time.

I used pin c0 for chip select. have any setting need?
