How to set both SPI and I2C at LPC54101

wk7575 · ‎10-14-2016

I use LPC54101. I make program with LPCXpresso v8.2.2 and Legacy LPCOpen v2.14.1 software package.
I want to use both I2C and SPI, but SPI is stuck by setting both I2C and SPI.
I2C' connection is down also. Please teach me how to set both SPI and I2C.
I2C is used to connect between LPC54101 and Edison.
SPI is used to connect between LPC54101 and MPU-9250(sensor).

Hi Koichi,

Did you try to test the SPI and I2C separately on your board?

Is the SPI and I2C working if just have one module?

How did you configure both I2C and SPI, and when the SPI is stuck? Please post some code about it.

Because I don't have the Edison and MPU-9250 on my side, then you should test it and tell me the result.

Waiting for your reply!

Have a great day,
Kerry
