A comprehensive list of resources that you can use to design applications using CAPSENSE™ controllers can be found here.

By default the I2C address of CAPSENSE™ Express capacitive controllers are all set to 0x00h. If the customer board needs to have two CAPSENSE™ Express parts, then the master should follow the below steps to avoid data corruption in the I2C bus:
Step#1: Master puts CE#1 in reset mode by pulling XRES pin high
Step#2: Master sends CE#2 configuration file (generated by PSoC™ Designer) over the I2C bus. Customer should select a different address for CE#1 & CE#2 in PSoC™ Designer to avoid address conflict.
Step#3: Master resets CE#2 (software reset or hardware reset)
Step#4: Master puts CE#2 in reset mode by pulling XRES pin high, this step is optional since after Step#3 CE#2 address will get updated from 0x00h to the user-configured value.
Step#5: Master sends CE#1 configuration file (generated by PSoC™ Designer) over the I2C bus.
Step#5: Master resets CE#1 (software reset or hardware reset).

Note:
i) CE#1 - refers to 'CAPSENSE™ Express' device #1
ii) CE#2 - refers to 'CAPSENSE™ Express' device #2
iii) For the above procedure to work, make sure that at least one of the CAPSENSE™ Express parts (out of the two) on board have the XRES pin bonded out.
