Introduction
The guidelines detailed in this document help designers cope with the limited number of channels. The number of touchkeys can be increased and/or a touchkey matrix can be created, keeping the same targeted device.
The touch sensing libraries allow management of the number of channels, which depends on the targeted devices (refer to the product reference manuals for more details).
