I have successfully configured CY8CMBR3108 capsense chip using EZ-Click and CY3280-MBR3 dev kit. I effectively used the dev kit as a I2C bridge.

I would like to have a method of programming CY8CMBR3108 in production i.e. I don't want to give EZ-Click to production operatives because they could change the settings. I want to pass them only .hex or .iic file generated by EZ-Click.

What PC software should I use? I have tried Bridge Control Panel but without success. It allow me to open .hex file generated by EZ-Click and recognizes CY3280-MBR3 but it does not seem to be sending data to the target device. Also it allows for editing the configuration so it's not good.

I have also purchased MiniProg3 but it does not support capsense devices despite its datasheet suggesting it could be used as I2C bridge.

In case anybody else having the same problem it has been resolved by rolling back firmware on RPM Systems programmer. Their support was helpful and provided me with the older working version of software.

The programmer firmware version that supports CY8CMBR3108 is 3.101 Later versions might not support this chip so be careful with updates.

Programmer firmware comes with MP Manager installer so if you download the latest MP Manager from the website and then update firmware it might not work.

The combination that works for me is: MP Manager 1.22.34 and firmware version 3.101

As for Elnec I contacted their UK distributor and it looks like they would have to add CY8CMBR3108 to their programmer.
