Nordic Thingy Connector

[Afnan Liaqat]

Hey Team,

Can anyone please share the layout of the Program and Debug connector on the Thingy? I don't have a 10 pin SWD connector readily available and need to start communicating with the device ASAP.

Any help is appreciated.

Thanks!

Here you go:

The pinout is standard for ARM SWD connectors.

Thank you so much Ketiljo for that.

Do you know if the Thingy supports data over UART aswell or it's only I2C? If it does, would you be able to help me figure out which pins it would be connected to on the Thingy.

You can find the HW description here: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.rds/dita/rds/designs/thingy/hw_description/hw_descr.html?cp=9_0_6

Remember that you can use any peripheral on any GPIO. Just define the the pins you are going to use in the SDK driver.

Thank you.

Maybe I should explain my application so that you can help me with the issue I am having. I am trying to read the data from the sensors on the Thingy using Arduino. I'm not able to find any other sensors except for Accelerometer on the I2C Bus (Address: 0x19) that is connected to P4, P5 and P7. I was reading through the User Guide and it said that there is another I2C bus where the rest of the sensors are connected. Do you know which pins would have access to the other I2C bus?

[ketiljo]

There are two I2C interfaces, internal at P0.07/P0.08 and external at P014/P0.15, see the pin maps. The accelerometer is connected to the external I2C interface, all other sensors to the internal I2C interface.

So basically that means that I cannot access those sensors from Arduino. We'll have to use the dev kit to develop a custom firmware and be able to use the MCU as a Microcontroller for our application.

Thanks for all your help. Now that I have a direction, I will reach back if I need any help with that process. Really appreciated!
