I2C timeout when using NT3H2111

hrj — Thu, 25 Jul 2019 13:12:13 GMT

Hello.

I've implemented bidirectional communication using SRAM as described in AN11579 using the NT3H2111 chip.

This works as a charm most of the times, but occasionally a command sent via I2C times out, and then the chip becomes unresponsive, and all subsequent commands times out.

I’ve tried to perform the soft reset as described in 9.3 p 42 in the manual, but that does not solve the issue.

What can I do except resetting the whole device?

Regards

Hi Henrik Rune Jakobsen,

Would you please download the MCUXpresso SDK with NTAG I2C software component added?

Then you will find the ntag_i2c_explorer_demo in it's folder.(for example: ...\SDK_2.3.1_FRDM-KL02Z\boards\frdmkl02z\demo_apps\ntag_i2c_plus\ntag_i2c_explorer_demo)
It will show you how to use pass-through mode.

Best Regards,

Robin
