https://devzone.nordicsemi.com/f/nordic-q-a/88018/led-strip-driver-chip-ws2812b-api-for-nrf52840Hi I am currently using an nRF52840 SoC and I already have both I2C buses in use, as my application requires multiple I2C sensors with the same address. That means I can&#39;t use the SPI peripheral. However, I also need to control some led strips (ws2812ben-USTelligent Community 13Wed, 18 May 2022 11:14:42 GMThttps://devzone.nordicsemi.com/thread/368300?ContentTypeID=1Wed, 18 May 2022 11:14:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:017aa536-5cdf-4b22-81fe-f9cfb5a9dcdaJ&#248;rgen Holmefjord<p>Hi,</p> [quote user=""]edit: well, I just realize that nRF52840 SoC has 3 SPI <span>peripheral so I can&#39;t use the SPI1, SPI2 but can use the SPI3&nbsp;peripheral right?</span>[/quote] <p>Actually, nRF52840 have <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/spim.html#topic">4 SPI peripheral instances</a> (SPI(M)0, SPI(M)1, SPI(M)2, and SPIM3).
