Using SPCE061A to develop a data acquisition system has great market prospects. First of all, its easy-to-learn and easy-to-use programming voice and development environment allow beginners to get started quickly; secondly, it has a modular structure and built-in 7-channel 10-bit AD, simplifying the user's circuit design; thirdly, it has voice Recognition and audio processing functions allow users to develop more intelligent products
This evaluation kit supports the fully integrated MC34717EP Dual Switch-Mode Power Supply—a dual-synchronous, buck-switching regulator.
The TEA2095 add-on board is designed for incorporation into existing resonant power supplies by replacing the secondary rectifier diodes. The add-on board consists of the TEA2095 Dual SR controller IC and low-ohmic MOSFETs in LFPAK package.
The MAXREFDES9000 is a reference design showcasing the DS28E18 that demonstrates how to both operate and power remote I2C and serial peripheral interface (SPI) sensors using only two wires
This design is a digitally controlled DCDC converter. MCU is used to control the output voltage of the DCDC converter to achieve the purpose of numerical control. Considering the time and cost, finished modules are used for verification. This design idea is simple and reliable. And it has the advantages of low cost and high flexibility. The function to be realized is to control the output voltage of the DCDC module with buttons and digitally display the voltage and current values.
A MEMS acceleration sensor is used to convert the vibration signal into a voltage signal. The MCU collects the voltage signal into the MCU through the ADC module. Then the time domain signal is converted into a frequency domain signal through FFT changes, and the conversion result is displayed through the OLED module. This basically completes the function of the vibration analyzer.
The temperature is used as the controlled variable in the fermentation process, the ventilation air supply volume is used as the manipulated variable to regulate oxygen, the GD32E231 microcontroller is used as the main control unit, and the output relay controls the fan to regulate oxygen. , through the design of hardware circuits and related application programs, the four processes of fermentation are adjusted to achieve the effects of accelerating compost maturity and improving fertilizer efficiency.
The development of the water level measurement voice alarm device is based on GigaDevice Innovation GD32E231C-START evaluation board. It can measure, display, give voice warnings, and report water levels to the cloud. Suitable for IoT monitoring of containers holding liquids such as rain counters and small water tanks.
This design is based on the design and development of the Modbus_RTU (RS485) bus Remote Inputs/Outputs Modules system of GD32E231.
