Hello everyone!
Here is some information on how to design CapSense sensors while developing Capacitive sensing applications in PSoC 6.
Schematic design:
After selecting PSoC device, while designing schematic you can refer to the following documents:
1) PSoC 6 datasheet (depends on the selected device)
2) Schematic Rule checklist section in AN85951 - PSoC 4 and PSoC 6 MCU CapSense Design Guide (http://www.cypress.com/file/46081/download)
3) AN218214 - Hardware design considerations (http://www.cypress.com/file/385701/download)
Layout design:
While designing PCB, refer to the following documents:
1) Design considerations section in AN85951 - PSoC 4 and PSoC 6 MCU CapSense Design Guide (http://www.cypress.com/file/46081/download)
2) Specifically, layout rule checklist section in AN85951
3) For proximity sensor design, refer to AN64846 - Getting Started with CapSense (http://www.cypress.com/file/41076/download) and AN92239 - Proximity Sensing with CapSense (http://www.cypress.com/file/46741/download)
Following the above mentioned guidelines in various documents will help achieve high SNR, better performance and electromagnetic compatibility.
