Hello,
I am working with the nRF DK trying to read a sensor over I2C. I wrote some code in Keil uVision and I finally could read the sensor. The problem now is, for some weird reason I can't figure out, the twi_sw_master.c file gives some compilation errors.
compiling twi_sw_master.c...

I can't understand what the problem is. I researched about #254 error but the explanation doesn't help that much.
This is the file:
github.com/.../twi_sw_master.c
I used that file because I was getting compiling errors with the original one. I am getting the same errors with the new.
Does anyone know what the problem is?
Thank you.
