Additionally, it includes an expandable connector designed to interface with custom boards, enabling extended functionality. This flexibility supports development across various use cases, such as inductive sensing, liquid level sensing, and hover touch applications.

Development Environment and I/O Access

The board is supported by ModusToolbox™ BSP, allowing seamless firmware development and integration into a broader development workflow. With access to multiple I/Os, developers can quickly prototype and test sensor applications, evaluate signal behavior, and customize input/output behavior for targeted use cases.

Getting Started with CY8CPROTO-041TP PSOC 4100T Plus Prototyping Kit

Follow these steps to start using CY8CPROTO-041TP PSOC 4100T Plus Prototyping Kit: 

Step 1: Power up the kit

a. Ensure that the jumper is populated at header (J2). 

b. Connect the board to your PC using the USB-C cable at USB-C connector (J1) and observe that the power and status LEDs (LED1, LED4) turn on. 

Step 2: Test the operation

a. Touch one of the capacitive buttons (either CSB1 or CSB2) and observe that the LED2 (red) or LED3 (green) turns on respectively. 

b. Swipe on the touchpad (CST1) and observe that the brightness of LED2 (red) and LED3 (green) changes corresponding to finger position on the touchpad. 

c. Hover your hand over the capacitive proximity sensor (CSP1) and ensure that the brightness of LED5 (blue) changes with proximity. 

d. Ambient light sensor (ALS) detects changes in illuminance and adjusts the brightness of LED6 (amber) accordingly.

Applications
