Embodiment 1

[0042] A TivaMCU plus an LCD is connected through the common interface of BoosterPack. The other end of the USB is connected to the host computer to debug the PC.

Embodiment 2

[0044] It consists of TivaLaunchPad + target experiment module + LCD display module. Experimental teaching for modules can be completed. For example: if the target experiment module is a motor module, then the whole solution is to provide the PWM signal required to drive the motor module through TivaLaunchPad, the module uses the driving signal to start the motor, and the signal of the motor impeller cutting the infrared tube is fed back to the MCU to count and count the number of revolutions Send the rotation number information to LCD display.

Embodiment 3D

[0045] Example 3 DC-DC-Boost power boost module experiment

[0046] It consists of TivaLaunchPad+LCD display module+ADC function module+PWM function module. Among them, the program in TivaCortex-M4 generates PWM wave through PB7 port to control the work of tps61165, and completes LED string lighting and current control. The duty ratio of PWM wave can be adjusted through the scroll wheel on the LCD development board to realize current adjustment; through PE2 The ADC function reads the output voltage of OPA330 in the voltage measurement circuit, and calculates the voltage value of the measurement point according to the circuit schematic diagram, and displays it on the LCD; reads the output of the INA213 in the current measurement circuit through the ADC function of PE3, and according to The circuit schematic diagram and the magnification of INA213 (50 times) calculate the current value of the measurement point and display it on the LCD. See attached for specific work flow chart...

Abstract

The present invention relates to an electric and electronic technology experimental device. The electric and electronic technology experimental device comprises a mother board and a daughter board which can be plugged with the mother board, and the daughter board comprises an LCD module, a DC-DC boost module, a DC-DC buck module, a motor module, a resistor measurement module, a high speed voltage-controlled module, an MDAC module, a frequency-phase-lock module and an LED module. The mother board comprises an MCU, a communication module and a memorizer, and the communication module comprises a USB, a UART, an I2C, an SSI/SPI and a CAN. During the experiment process, by just needing to insert the experimental modules on the mother board, the modular design facilitates improving the attentions of the students on the experimental parts, and the electric and electronic technology experimental device has the advantage of integrating the simplification, versatility, portability, modularization as one.

Description

【Technical field】 [0001] The invention relates to a test device, in particular to an electric and electronic technology test device. 【Background technique】 [0002] Most of the analog circuit experiment boxes used in the traditional electrical and electronic technology fields are designed to intuitively lay the classic analog circuit design circuit scheme on the test box, and learners complete learning and experiments through complex jumpers . Due to the limited layout of the circuit, it is difficult to include most of the analog circuits in a test box. All in the teaching, it often needs multiple similar test boxes with different circuits to complete all the involved content of the analog circuit, and the original test box often needs a large number of supporting instruments such as oscilloscopes and multimeters to complete. . Although the traditional university test box has powerful functions and covers a wide range of knowledge, it also has many disadvantages such as l...
