twi pca10040e example - sdk15.0 SES

[Simon]

Is there at least one twi example available that uses pca10040e? Not seeing one in sdk15.0 for SES.

I can get the code working for pca10040 on s132 but not for nrf52810 s112.

Error of unknown type name 'NRF_TWI_Type'

in definition of macro 'offsetof'

Looking for a sanity check by using a working twi 40e example.

Hi,

Project for pca10040e emulates nrf52810 which does not have a TWI, hence NRF_TWI_Type is not known.

You need to use TWIM peripheral with nrf52810.

[Simon]

that's fine, then looking for an twim example for pca10040e.

Hi,

Please find attached SES project for pca10040e for twi_scanner example.

Unpack below package under following location: sdk\nrf5\examples\peripheral\twi_scanner

pca10040e.zip

[Simon]

zip compiled fine, thank-you

I was looking for a continuation of your suggestion of using only twim but also nrfx, with no legacy

for example, instead of nrf_drv_twi_init(), use nrfx_twim_init().

no includes of nrf_drv_twi.c in the project.

-thank-you.

Hi Jakub,

I am also trying to use TWI with nrf52810. I downloaded and ran the code you posted below and it compiled fine (thank you for posting that by the way), however I noticed it uses TWI functions such as nrf_drv_twi_init() instead of the TWIM nrfx_twim_init(). Should I be using the TWIM peripheral as you said above instead? What are the differences/advantages? I've been having quite a hard time determining which TWI driver(s) to use/which files to include, any advice would be greatly appreciated.

Thank you,

Charlie
