Hello

We are using stm32l432 MCU interfaced with TI TMP107BID for sensing 28 digital temperature sensors.

We would request you to provide a sample software C code to configure this TI chip and get the Temperature data through One-Wire Interface and protocol.

Do we need UART peripheral or I2C peripheral in our STM32 MCU please to support this TI chip temperature reading functionality?

Many thanks

With kind regards

Hello

It will be grateful, if you could share the one wire interface / protocol with STM32 Microcontroller please.

Hello Siva,

You can find a code example below. This uses GPIO for the interface on the MSP430.

We have also recently released the TMP1826 and TMP1827 devices which offer a 1-wire interface. These may be of interest for your application.

For TMP107, please reference the TMP107 Firmware associated with BOOSTXL-TMP107. This is the official release of the code example shown in the referenced E2E post.
