Design Tips
Question 1:
Answer 1:
Ensure that you are using the correct SPI mode for that device. This SPI supports two of the four
SPI modes so ensure that the SPI device that you are trying to interface to is compatible with one
of these two modes. Check the clock polarity and the clock phase.
If the device is not compatible, switch to one of the Microchip devices that has the SSP module,
and that should solve this.
Question 2:
Answer 2:
This SSP module does not have master mode fully automated in hardware, see Application Note
AN578 for software which uses the SSP module to implement master mode. If you require a fully
automated Hardware implementation of I
Card for devices that have the Master SSP module.
Question 3:
Answer 3:
Ensure that you set the CKP bit to release the I
Note:
At the time of printing only the High-end family of devices (PIC17CXXX) have
devices with the Master SSP module implemented.
Using SPI mode, I do not seem able to talk to an SPI device.
