Hello, I'm a newbie in Renesas environment, and I'm starting a Cap Touch Project using a fresh installation of e2studio and QE for Captouch.
I have an EK-RA2L1 dev board + a cap touch board "home made" (3 buttons).
After doing all steps reported in the Application Note "Using QE and FSP to Develop Capacitive Touch Applications" (R01AN4934EJ0110 Rev.1.10), when I launch "Start Tuning", I see a message in the console (momentarily, then is overwritten by other messages) "TSCAP VOLTAGE ERROR........". Then the tuning aborts with the message:
Can't find a source file at "C:\project_IDE\e2studio\e2studio_ra_ver202007N20200409\workspace_tuning_program_RA2L1\tuning_program_ra2l1\Debug/../src/tuning_ctsu2.c"
1) reading the documentation I can't understand with certainty how TSCAP pin should be wired: only a 10nF Capacitor between TSCAP and GND or, also with an external voltage (3.3V) in parallel with capacitor?
2)I can't locate the tuning_ctsu2.c file. Where is should be located?
How's it going? You might want to refer to the user's manual. The user's manual says in page 9, "do not connect anything to TSCAP". Also, you might want to refer to QE for Capacitive Touch[RA] V1.2.0 release note for the installation process indicated in page 4.
I hope that would be helpful.

Hello Sai, thank you for your answer.
I missed the manual with that advice.
Do you think I damaged the CTSU interface by connecting a 3,3V on TSCAP pin?
I have been deceived by the indication above, that speaks of "secondary power supply pin".
Probably a "typical application schematic" on the MCU manual could wipe away any doubt.
Thanks for sharing.
