I'm also unsure on how to link the MC36XX TWI functions to Segger Embedded Studios as it mentions on page 9 of the guide:

I really need help obtaining these values by the end of today so any help would be appreciated! Thanks.

I've edited my code as follows but in putty, empty spaces are being printed in a loop. Do you think this could be due to an error in my code or the circuit itself? I'm unclear about what the purpose of setting FIFO is as well, thanks for your help!

Hi,

Thanks for your reply. I'm not sure what you mean by logic analyser trace? Sorry, reading two ReadData() values is a mistake in my code. The ReadData() function should return the number of samples being read but I don't understand the role of faOuptut and how I should declare the data buffer to store the output data (as mentioned on page 21 of the guide)?

Hi,

Do you have a logic analyzer trace of the twi communication?

Have you looked into the return value of M_DRV_MC36XX_ReadData() and what it may mean? Looks like you are calling multiple M_DRV_MC36XX_ReadData(), are you checking return value of them all?
