SPI 18F46K22

This one is odd in channel mode.
With the FT800 Flowchart.
chip select is not working at all.
When added output icons for chip select the MOSI finished low instead of high.
Most data was correct except for the end of course.

Hi Martin,

Hmm this sounds pretty odd. Maybe check the Auto Chip Select property in the cal_spi component is set to disabled? I noticed it was set to enabled in the last program. Shouldn't cause too many issues though as long as the pin is valid.

The chip select is driven in the FT800 macros via references to the root component CS pin property.

Could it be a config setting clashing with the pin stopping it from being enabled as an output?

Out of interest which pin is it?

Hi Ben,
Thanks for your reply.
I will check out your suggestions.

Out of interest which pin is it?

Pins setup:

Code: Select all

SCK  - C3
MISO - C4
MOSI - C5
CS    - C7

What about MOSI finishing low rather than high?
I will of course double check that when trying your suggestions.
