TM121TEMP(4)

🎀 NAME 🎀

Hiii bestie, welcome to the Kernel Interfaces Manual page for tm121temp — the Texas Instruments TMP121 temperature sensor driver. It’s giving tiny temperature-sensor main character energy, and we’re gonna get into all of it. 💖

✨ SYNOPSIS ✨

The config line is literally this, no cap:

tm121temp0 at spi? slave 0

🦋 DESCRIPTION 🦋

So the tm121temp driver provides support for the Texas Instruments (formerly Burr-Brown) TMP121 temperature sensor with the envsys(4) API. Obsessed. These devices are connected to the host system with spi(4) or Microwire 4-wire serial busses. 🫶

The tm121temp is capable of measuring temperatures with a 2 degree accuracy over the frame from -40 to 125 Celsius. Temperatures are reported with a granularity of 625 microKelvins. That is so specific of it. 💅

tm121temp devices can transfer information at up to 10MHz, and support SPI mode 0. Slay. 🔥

The device reports itself with envsys(4) using the generic device name. This name can be overridden by specifying an alternate name in the device property “envsys-description”. Cute, customizable, iconic. ✨
