How can I use SPI and I2C interrupt at the same program in nRF52832?

[chianglin]

Hi,

As well know, nRF52832 have more then one SPI and TWI interface.

How can I use SPI and TWI interface in the same program? for example, use SPI-0 and TWI-1.

Thank you,

Ives

Hi,

1. You need to enable both peripherals in the project sdk config file.
2. Add the proper source files for both peripherals. This usually consists of the drivers for the peripherals.
3. Add the path to the source files to the projects settings.
4. Initialize the peripherals in the project 
5. Use them

The easiest approach is to merge the example projects in the SDK together. For example twi_scanner + SPIM example.

Hi,

Thank you for your answer and example code.

If I want change twi or SPIM to 2nd interface, how can I modify config-file and source code?

Thank you

By interface you mean instance?

Hi,

If I want change SPI interface to SPI-1, then I need modify the "SPI_INSTANCE" to 1?

How to change the setting of config file?

Does I need change "event handle" function?

Thank you

You need to change this part in the example code:

And enable it in the sdk_config file:

Hi,

Thank you for your answer.

But I can not found NRFX_SPIM3_ENABLE define in sdk_ovnfig.h.

Please found the attach file

4604.sdk_config.h

Thank you

Hi,

The screenshot I shared was from a config file for the nRF52840 which has 4 SPIMs, nRF52832 that you are using has less which is why you can't find it in your config file. The screenshot was only meant to be an illustration of where you enable/disable the config.
