NHS3152UK/A1Z

Hello,

I am designing a new board around the NHS3152UK/A1Z product. I have the following specific questions:

1) I have no need for a hardware reset. What should I do with the RESETN Pin (leave it unconnected, tied to VCC, or what)?

2) If I don't use the RESETN Pin (as I intend) how can the device be reset during the firmware development? Note that for firware development, the intent is to use the development board refernced in NHS3100 Sensor Board | NXP Semiconductors using I2C pins to download the firmware.

3) Can the NHS3100 Development Board be used to develop firmware for the NHS3152 Device?

1. Connect to VCC with a pull-up resistor.

2. Use software reset if RESETN not use

3. Yes for initial development. It is better to use NHS3152 board as there are some features different.

Thank you for your prompt response.

We have completed the hardware development. Now, I need to get started on the custom firmware we would like to run the NHS3152UK/A1Z Device. I am a fully-experienced C/C++ Programmer but need some help to get started, as listed below:

a) I would like a link to the Eclipse IDE to download and install on my development platform

b) I need a "walkthrough" to show me the main steps for loading a simple (like the Blinky) application source code into Eclipse, build it and deploy it for testing

Please help me with the above steps.

Regards,
