Gt1tS5A

Simple Temperature and Humidity Detector - LCSC Online Training Camp

Overview

This
desktop temperature and humidity meter uses an SHT40 microcontroller to detect indoor temperature and humidity. Data is displayed using two 3-digit common-cathode LED displays. It is powered by two AA batteries and remains in sleep mode when not in use. The estimated lifespan is 6 months.

The project uses the STM32G030K6T6 chip as the main control chip. This chip uses an ARM-Cortex-M0+ core with a maximum frequency of 64MHz, 32KB of Flash and 8KB of SRAM, and operates between 2.0V and 3.6V, which is more than sufficient for a desktop temperature and humidity meter.
All code in this project is generated using STM32CubeMx software, which is simple and easy to use.

Considering
that most students learning this project are beginners and have limited experience with the G0 series, and that online resources for the G0 series are less abundant than for the traditional C8T6, STM32CubeMx software is used directly for basic code generation and configuration. The graphical interface reduces learning time and allows for quick start-up. The STM32CubeMx
software
can be downloaded and installed from the official ST website or the ST Chinese website. This will provide the latest version. (ST MCU Chinese website download address,

The first hello, world program compiles without errors, but when executed it prompts: Connection was not created
The emulator can be opened, and then a message pops up saying Connection was not created. It is not a problem with the emulator settings. I have already selected Win32 [WCE emulator] and the standard

Can STM32 use a timer to control PWM output
There are two waveforms, one is wider PWM1, and the other is narrower PWM2. The requirement is that when PWM1 is at a high level, PWM2 has output, and when PWM1 is at a low level, PWM2 has no output.
How to use external memory?
When using off-chip memory, do I still need to download the program into the MCU? Can a blank chip be used?
