combine two different twi into a single function

[Menaka_12]

Hi!

I am using nrf52840,sdk 14.2,Keil IDE

I am using bmp180 and mpu6050 sensors.

In proximity code,I have integrated both sensors separately,It works fine.

But while combining two sensor codes,I have a problem because both have different twi function.I don't know how to make that into a single function.

I have inserted main file here for your reference.main.rar

Please help me to solve this(I am a beginner in this field.So please guide me)

Thanks

The standard approach is to have a layered approach:

https://en.wikipedia.org/wiki/OSI_model

That way, you separate the basic hardware operations - START condition, Addressing, ACK, NAK, transferring bytes - from the specific details for each sensor.

You will also need to make sure that your code for one sensor doesn't try to use the bus while your code for the other sensor is using it!

EDIT

The Nordic Thingy has several slaves on its I2C bus - so you could look at how that handles it ...

I would suggest that you work this out first without the added complication of BLE.

The I2C specification is here: www.nxp.com/.../UM10204.pdf
