Hi Sir/Madam,
In STM32CubeMX, the TSC in System core, we finding only group-2 with four I/Os. I am thinking that there must be group-1, group-3, group-4. So that we can implement TSC with more keys.
please suggest me proper settings required to do this.
Thanks & Regards

According STM32CubeMx:
On STM32WB55 QFN48 we support only 1 group (G2).
- 3 buttons (e.g)
- One Sampling capacitor (G2_IO1)
- 3 sensors (G2_IO2/3/4).
On STM32WB55 QFN68 we support 3 groups (G1 G2 G3).
- 1 Shield (e.g)
- One Sampling capacitor (G1_IO1)
- 1 Shield (G1_IO2).
- 6 buttons (e.g)
- One Sampling capacitor (G2_IO1)
- 3 sensors (G2_IO2/3/4).
- One Sampling capacitor (G3_IO1)
- 3 sensors (G3_IO2/3/4).

Hi Sir,
Initially, we chose the STM32WB55 (QFN48) it has only one group. Currently we required a slider (linear). So we are moving to the QFN68 package. In my case, i need six plus keys, So Can I avoid the shielding to get the 9 keys? One Sheilding I/O is enough to all the keys?
Thanks You
