Regarding twi sensor

Dear Sir,

I am using nrf52832 & sdk 14. When I dump your twi sensor code(SDK14\nRF5_SDK_14.2.0_17b948a\examples\peripheral\twi_scanner\pca10040\blank\arm5_no_packs) in the nrf52832 development kit there is no activity observed on the oscilloscope on the pins SCL(P0.27) & SDA(P0.26).

But when I tried the same thing on nrf51422, I got the clock pulses. 

So please tell me what is the problem with the nrf52832 & sdk 14 (I have tried this with sdk12 also).

Regards,

Manoj Hiwarkar.

  • I am getting the clock pulses on SCL & SDA  pins of the target board. But still I am not getting the data from the max30205. I am herewith uploading the two videos (both are with different time base) these clock pulses on the oscilloscope. 

    Blue line is SDA 

    Yellow line is SCL

    So please tell me where I am going wrong.
