User manual for DEV_KIT_NGC1081
About this document
Scope and purpose
This document describes the evaluation kit for
field communication (NFC). The kit has all the necessary components to enable the user to quickly start sensing
the world via NFC in active and/or passive mode. The required settings for both modes, for programming and
debugging, are covered in this document.
Intended audience
This document aims to help developers make use of the NGC1081 in NFC sensing applications. It can also serve
as a demo for customers when used to sense different parameters at the same time.
Reference board/kit
Product(s) embedded on a PCB with a focus on specific applications and defined use cases that may include
software. PCB and auxiliary circuits are optimized for the requirements of the target application.
Note:
Boards do not necessarily meet safety, EMI and quality standards (for example UL, CE).

(available in active and/or in passive mode). After going through one of the two options, the NGC1081 sends the results over UART. The results can be read using the Android app supplied with the board. Below is the flow chart of the firmware. - Page 15 User manual for DEV_KIT_NGC1081 System in operation Figure 10 measurement steps labeled on the EVAL_NGC1081 with the SHIELD_PASCO2_SENSOR After less than 2 s the result will already be shown on the UART terminal. 6. Additionally, if the phone is placed where the NFC antenna is, the result of the measurement will also be shown in the app.
