Help connecting to MPR-121

[DvSh_4663776]

I work with the PSoC 5LP Prototyping Kit, and I try to connect with the I2C to the MPR-121 component and read the values from it. Can I get some help on this? Can't figure out which register I'm supposed to send the commands to, and how it should be executed exactly.

Thanks

Hi,

Can you try my MCU Tester sample?

MCU Tester, a Swiss Army Knife for PSoC (CY8CKIT-059 version)

If it works with your sensor, then you can copy the i2c part of the program for your use.
