2018 Electronic Competition Question A-Current Signal Detection Device (Hangzhou University of Electronic Science and Technology)

Outstanding works of e-sports competition in 2018

Overview

This design is based on STM32F407ZGT6, passing the waveform generated by the arbitrary waveform generator through the power amplifier, increasing its current, and inducing the current through the winding coil. The induced current is converted into voltage and then amplified and sampled to measure the waveform frequency and amplitude. The current measurement accuracy is better than 5%, the frequency measurement accuracy is better than 1%, and the multiple harmonic components of any waveform within 1kHz. It has been verified that this solution has completed all functions.

Is it possible to migrate the GUI display using DDRAW?
I have made a program on MTK platform, and I wrote my own UI library. All the display is done by directly operating the video memory, which is very fast. But on WINCE, for the convenience of porting,
