https://bbs.21ic.com/icview-3471022-1-1.html
4. LPUART Wake-up from STOP Low Power Mode
https://bbs.21ic.com/icview-3471032-1-1.html
The SDK for the STM32U385RG includes an example for LPUART wake-up from STOP low power mode, which can be easily modified to achieve the functionality of this experiment.
5. Communicating as I2C Slave with CH347
https://bbs.21ic.com/icview-3471916-1-1.html
I configured the STM32U385RG as a Slave and the STM32H533RE as a Master, finding it easy to implement I2C communication between the two.
Then I wondered if using CH347 as a Master would also allow I2C communication with the STM32U385RG configured as a Slave?
6. FreeRTOS Tasks and Queues
https://bbs.21ic.com/icview-3471944-1-1.html
The goal is to implement FreeRTOS task and queue handling.
7. USB DEVICE MSC Device (RAM Simulated USB Drive)
https://bbs.21ic.com/icview-3472308-1-1.html
The STM32U385RG uses ThreadX+USBX to implement USB device drivers. The examples provided with the STM32U385RG do not include a device MSC example, so this article uses ThreadX+USBX to virtualize RAM as a USB drive.
8. USB CDC + AES Encrypted Communication
https://bbs.21ic.com/icview-3472902-1-1.html
To achieve encrypted communication between the USB interface and the host computer, the STM32U385RG is configured as a USB CDC device. The plaintext data collected by the ADC is encrypted using AES ECB, and the ciphertext is sent to the PC via CDC, where it is decrypted and displayed as the ADC collection result.
Evaluation Two
1. Introduction
https://bbs.21ic.com/icview-3468994-1-1.html
2. TFT Screen Display Driver
https://bbs.21ic.com/icview-3470144-1-1.html
Since the STM32U385RG development board does not have the relevant display device configured, I first completed the TFT screen display driver in a simulated manner to prepare for the subsequent hardware startup method. One major advantage of software driving is the flexibility in configuring pin usage, thus avoiding restrictions based on pin locations.
3. Communication Wake-up and Power Consumption Detection
https://bbs.21ic.com/icview-3470170-1-1.html
One requirement for the basic experiment is to wake up the STM32U385 from STOP low power mode via LPUART and demonstrate that the LED blinks normally after waking up.
4. A/D Data Collection and OLED Screen Display
https://bbs.21ic.com/icview-3470616-1-1.html
Combining the OLED screen display function with A/D data detection allows for direct observation of the detected data, eliminating reliance on serial output information. To achieve this goal, the following two environments are needed.
5. OLED Screen Display Driver and RTC Clock
https://bbs.21ic.com/icview-3470936-1-1.html
Having previously introduced the software simulation method to drive the OLED screen, it is much easier to attempt hardware driving after achieving success with the software method, as the main work for hardware driving is configuring the I2C initialization function and changing the I2C data byte transmission, with little else needing adjustment.
6. TrustZone and Its Testing
https://bbs.21ic.com/icview-3478041-1-1.html
The STM32U385RG belongs to the STM32 ultra-low power family, with a core based on the 96MHz high-performance Arm® Cortex®-M33, which integrates Arm TrustZone® and a hardware encryption accelerator.
7. LCD Screen Hardware Driver
https://bbs.21ic.com/icview-3478148-1-1.html
Having previously introduced the software simulation method to drive the LCD screen, it is much easier to attempt hardware driving after achieving success with the software method, as the main work for hardware driving is configuring the SPI initialization function and changing the SPI data byte transmission function, with little else needing adjustment.
8. Multi-Data Item Collection and Waveform Drawing
https://bbs.21ic.com/icview-3478242-1-1.html
In the examples provided by the manufacturer, there is a sample for ADC conversion across multiple channels, which configures the ADC for single conversion mode, triggered by SW.
9. PWM Control for LED Adjustment
https://bbs.21ic.com/icview-3478299-1-1.html
The examples provided by the manufacturer include multiple PWM channel outputs with fixed duty cycles, but lack an introduction to changing the duty cycle. Therefore, I attempted to automatically change the duty cycle and change it via a button.
10. Communication and Haptic Control
https://bbs.21ic.com/icview-3478447-1-1.html
It is very important to convey perceived danger information to them before an unexpected event occurs. So how can we solve this problem? We can transmit the collected danger information in a haptic manner, such as when a flame sensor detects danger, it can wirelessly communicate to a bracelet equipped with haptic vibration effects to alert them.
To simplify the information transmission process, I will first control the haptic motor’s vibration via serial communication.

2. PWM Adjustment of Screen Brightness
https://bbs.21ic.com/icview-3472158-1-1.html
In the evaluation plan, PWM is used to adjust screen brightness, so this article explains how to use HMI to achieve brightness adjustment. The principle is to use TouchGFX Designer to add a sliding control to modify the PWM duty cycle, thus adjusting the voltage of the ST7789 BLK.

7. Obtaining Temperature Values from the STM32U385RG Board’s Temperature Sensor
https://bbs.21ic.com/icview-3477586-1-1.html
Many people do not know that the STM32 chip has an internal temperature sensor, so most people’s approach is to connect an external temperature and humidity sensor for testing. In fact, unless it is necessary for a project, there is no need to connect an external temperature sensor to test the board’s temperature, as the internal temperature sensor of the STM32 can be used directly.
8. Uploading the Temperature Value of the NUCLEO-U385RG Board to the MQTT Server

I often use Keil for development on ARM architecture microcontrollers. For this activity, I also used this development software. For the STM32U385RG’s low-level driver part, I used STM32Cube MX software for configuration, which is very convenient, and mastering the HAL library operations makes development very easy.
