#95779 - SPI with not response Responding to: ???'s previous message |
I have very little experience with SPI; however with other serial interfaces I have found it VERY useful to test the code and hardware with a "responding" device (e.g. a serial memory) when coding for devices with no response.
I know not if your code or hardware for the interface is good or not and am just suggesting a technique for eliminating the interface as a possible cause of your problems. Erik |
