TMP126 Digital Temperature Sensor Module and its Driver

Overview

The project utilizes the TMP126 digital temperature sensor chip. A module was designed based on the chip's datasheet, and its schematic is shown below.

Since readily available driver code for the TMP126 is scarce online, a driver program for the TMP126 was developed based on the STM32F103C8T6, and the measured temperature is displayed on an OLED screen. To facilitate future development by engineers, the driver code for this project is open-sourced. The wiring diagram for this project is as follows:
TMP126STM32:
PA0->CS, PA1->CLK, PA2->MOSI, PA3->MISO.
OLEDSTM32:
PB10->SCL, PB11->SDA.
The temperature display effect is as follows:

The first line displays the actual measured temperature, the second line displays the hexadecimal value of the actual measured temperature, the third line displays the read device ID, and the last line displays the value of the TMP126 configuration register.

RFID tags will reach 20 billion in 2008
[Abstract] According to a research report published by an authoritative consulting agency, by 2008, 20 billion radio frequency identification (RFID) tags will be used annually worldwide, most of which
DAC7621 Application Issues
When I was using DAC7621 12bitDAC, the ripple noise was large. The DA output was almost a square wave without a filter capacitor. After adding a 10uF capacitor, the ripple was 40mV. Schematic diagram:
Ask for advice on the SDRAM experiment in "Playing FPGA in Simple Ways"
Please help me analyze this, when I was doing the SDRAM experiment of a privileged classmate, why did the data I sent through the serial port look like this? 01 02 03 04 05 06 07 07 09 0A 0B 0C 0D 0E
Capacitor voltage reduction
[size=4] Recently, I followed my teacher to prepare for a water treatment project. During the preparation process, I encountered a small problem: the problem of power supply voltage reduction. Before,
What is the issue with WinCE's language support?
Under wince5.0, the default language of the system is English. I first added simplified Chinese display support under "Core OS" -> "International" -> "local specific support". After customizing the ke
