I have an MPR121EVM KIT and I was wondering if the source code for the demo that is supplied with it is available. It would seem to be a nice starting point to further evaluate the MPR121 touch sensor.
If not the source code, is the binary available so that I can restore the demo application after I load my own program?
Thanks
Larry
Hi Larry,
Unfortunately I do not have the source code that is embedded in the MC9S08QG8 that controls the MPR121 on the KITMPR121EVM.
I can only share the source code that is available for the TWRPI-MPR121 (TWR-SENSOR-PAK MPR121 plug-in module) or for the MPR121 breakout board.
I hope you will find it useful.
Regards,
Tomas

Hi Tomas,
Thanks for the reply.
Is there some way to restore the included application if I erase the one that ships in the device?

Larry
Hi Larry,
Yes, you can restore the original application using the KITMPR121EVM_Bootloader.s19 file that is located in the Bootloaders folder (C:\Program Files\Freescale\Sensor Toolbox\Bootloaders).

Hi Tomas,
Actually I guess my real problem is that I cannot find any documentation on the Sensor Tool Box Application for the MPR121. The tutorial button is grayed out, the button for the documentation does not work,( a command prompt window opens then closes) and the help button just displays the generic quick start info.
I see that there are ERASE and UPDATE Firmware buttons on the application but is there some information on how this works? Is there a link that contains all of this information?
Regards
Larry
