ProxSense line management

ProxSense line management overview
Since the STM8TL5xxx provides a ProxSense interface, it is mainly used to perform
capacitance variation acquisition.
The principle of this interface is to transfer a charge from a capacitance (the electrode CX) to
another one (the sample CS, inside the MCU) by driving the PXS_TX and activating some
switches. This allows detection of proximity as well as touch by monitoring on PXS_RX.
The many features of the ProxSense interface include:
●
10 independent receiver channels, allowing 10 measurements to be performed in
parallel
●
Each of the 10 receiver channels can be associated with two different pins, effectively
allowing an application to have up to 20 receiver channels.
●
Each receiver channel can be independently configured to perform projected
capacitance measurements.
●
The size of each CS capacitor can be independently configured with 5 bits of resolution.
Figure 6 shows a simplified functional schematic of the ProxSense interface.
