I just looked at the wiring for the Thunderboard Sense 2. It is crazy…. Normally all of the I2C devices on a board are wired to a single I2C Bus. But the designers of the Thunderboard decided to conne

Hello there, I'm trying to connect my board (nrf52dk-nrf52832) to a development kit, through I2C, which has external pull up resistors. I would like to configure the I2C port to accept the external pu

Have you tried to connect a logic analyser to your I2C pins to see if there are any transactions occurring? Thanks, Jeremy

Hello guys, I would like to implement an application with NFC tag reader via NXP PN532 or other NFC controllers, which communicates with board via I2C, is there any suggestion or sample to follow how

After further testing, I found that if I step through each instruction with the debugger the individual messages send correctly, but not if I let the program run regularly. In neither case does the i2

I forgot to include the overlay file…here it is.

Hi there, I suspect that sample requires a specific .conf file for nRF52840, since it fails on an invalid GPIO Kconfig symbol. Adding Mieszko and and Andrzej from Nordic. Carles
