I2c with Grid eye sensor

[Madhuri]

hello ,

I am interfacing Grideye AMG8832 with Nrf51822. The initialization part is executed without errors but ON trying to recieve or transmit it gives error of TWI as shown in the screenshot attached.I have tried with 0x68 address and even with variants of memory address.

I am using SDK 9 with the example link text

as shown in this link text

please guide through this!

main.c

thank you

the sensor does not acknowledge the address, see error_src. Are you sure you're using the correct address for this sensor? Do you se the same if you try with 0x69?

[Madhuri]

yes i did with 0x69 , 0x68/9 >> 1, it dint work.

[Vidar Berg]

then I would suggest to use a logic analyzer/oscilloscope and verify that sensor is addressed correctly.

There is some code posted here that may help you. www.pureengineering.com/.../grid-eye-breakout

thank you sashi,

i had seen that .but they have provided a arduino code and a reference manual which i have already referred to. I have put the address and sequence the same as arduino code, but still it doesnt work.
