I2C Test For Microchip board

############################

|
|

|
|
This application test is used to test the I2C driver on Microchip
|
||
|
|
mec15xxevb_assy6853 board.

Board Hardware Setup

####################
|
||
|
|
|
||
|
|
As the I2C slave device NXP pca95xx on mec15xxevb_assy6853 is connected
|
||
|
|
to I2C00 port, however, I2C00 port is shared with UART2 RS232 to TTL
|
||
|
|
converter used to catch serial log, so it's not possible to use UART2
|
||
|
|
and I2C00 port simultaneously.
|
||
|
|
We need to change to use I2C01 port by making some jumpers setting as below:
|
||
|
|
|
||
|
|
* JP99 1-2 Connected Connect I2C01_SDA from CPU to header J5
|
||
|
|
* JP99 13-14 Connected Connect I2C01_SCL from CPU to header J5
|
||
|
|
* JP25 21-22 Connected External pull-up for I2C01_SDA
|
||
|
|
* JP25 23-24 Connected External pull-up for I2C01_SCL
|
||
|
|
*
|
||
|
|
* JP44.1 J5.1 Connected Connect NXP PCA95xx to I2C01
|
||
|
|
* JP44.3 J5.3 Connected Connect NXP PCA95xx to I2C01
