This solution allows designers familiar the use standard microcontrollers to create higherend human interfaces by replacing conventional electromechanical switches by capacitive sensors. The xxxxtouchlib is part the application firmware. It allows combining various capacitive sensing touchkeys, linear or rotary touch sensors traditional MCU features (communications, control LEDs, beeper or LCD) in the same application. Two capacitive acquisition principles, surface Charge Transfer (CT) and ProxSense TM, are and can be configured at compiling level. Both acquisition principles fer the same advanced processing algorithms to filter out noise and to compensate environmental parameters such as temperature, humidity, and power supply variation. Note: ProxSense is a trademark Azoteq (Pty) Ltd. Reference xxxxtouchlib Table.

5 xxxxtouchlib ProxSense (PXS) acquisition principle ProxSense (PXS) acquisition principle This peripheral operates in Projected mode which is used to measure the charge transferred by a driven electrode to a second electrode. This acquisition principle is only on STM8TL5x devices. For more information see the STM8TL5x Reference Manual (RM2). 2 Surface charge transfer (CT) acquisition principle The surface charge transfer acquisition consists in charging the electrode capacitance (C X ) and transferring part the accumulated charge into a (C S ). This sequence is repeated until the voltage across C S reaches a given threshold. The number transfers required to reach the threshold depends on the size the electrode capacitance. The CT acquisition can be managed in three different ways: using the touch sensing controller (TSC) on STM2Fxx and STM2Fxx devices using the routing interface (RI) only for STM8L and STM2Lxx devices stware acquisition using the routing interface (RI) and two 6bits timers for STM8L and STM2Lxx devices hardware acquisition. Please see the Table 2 for more details about the peripherals used. DocID29 Rev 5/59 58
6 STMTouch Library architecture xxxxtouchlib STMTouch Library architecture Note: The STMTouch Library is a package composed different elements: the STMTouch driver directory contains the firmware layer to perform the touchsensing acquisition and the sensors processing. This driver contains all the acquisitions for all supported microcontrollers. This is the core the STMTouch Library the STMTouch examples directory contains a set firmware examples to show how to use the STMTouch driver the Standard Peripherals driver directory contains the firmware layer to access the standard peripherals the CMSIS driver directory contains the Cortex microcontroller stware interface standard (STM2 only) the Utilities drivers directory contains the drivers to access for example the LCD on the evaluation boards. There is one STMTouch Library per microcontroller family (STM8L STMTouch Library, STM8TL5x STMTouch Library, STM2Fxx STMTouch Library, STM2Fxx STMTouch Library, STM2Lxx STMTouch Library...). Figure and Figure 2 show the STMTouch driver layers. Figure. STMTouch driver architecture 6/59 DocID29 Rev
