Nowadays i am experimenting with XBee® ZB SMT modules. I have communicated with XB24CZ7PIS-004
over UART with no problem. I send data to the module and received it from an zigbee to ethernet router. But when i try to communicate over SPI, i couldn't.
I am sending a 0x55 byte over SPI to the Xbee module once in every second. In this figure
, you can see the preferred SPI clocking at the upper image and you can see the my SPI clocking in the lower image.
In the figure
• 2nd channel is Chip Select
• 1st channel is MOSI
• 4th channel is clock
Communication is one way so i did not included MISO signal. I think i implemented SPI communication in correct way but as i said, i cannot get any data from the router.
Can you help me on this issue?
