Using 2 spi (sd-card + 1 audio chip) and I2C simultaneous

[tuyenpham84]

Dear all,

I'd like to use 2 spi and 1 i2c at the same time. Can nrf52 support? I read some thread said that only using 1 spi and i2c or 2 spi. Please advice.

regards

There are several chips in the NRF52 series.

The NRF52832 and NRF52840 can support 2x SPI and 1x I2C at the same time

Thanks Turbo J,

I mean double check with NRF52832 also. So far, we're using nrf52832.

Hi, 

You should be able to use two SPI instances and a TWI(i2C) instance at the same time, according to the memory instance table in the nRF52832 Product Specification.

0x40003000 TWIM TWIM0 Two-wire interface master 0
0x40004000 SPIM SPIM1 SPI master 1.
0x40023000 SPIM SPIM2 SPI master 2.
