Hello Soichi,
We do not have a sample CAN application, as there is not currently CAN support with the Linux kernel/MQX for Vybrid Tower.
The MQX portion of the Vybrid Out of Box Experience Demo (OOBE Demo) uses the ADC. The sources are available from the MQX Installer, found here:
http://www.freescale.com/webapp/Download?colCode=FSLMQXOS_4_0_2_GA&appType=license&location=null&Par...
Please note, the ADC portion of this demo is commented out as it was previously not compatible with Linux. You can uncomment this code (lines 279-309 in FreescaleMQXRTOS4.0.2-GA/mcc/examples/oobe/ds5/oobe_twrvf65gs10_m4/Source/main_task.c ) when using the latest Linux kernel release by Timesys.
Build and runtime instructions can be found here:

Thanks, and let me know if you have any questions.
