Nuvoton NUC501 MCU micro thermal printer solution circuit diagram and source code

Overview

The composition and working principle of the micro thermal printer based on NUC501MCU are analyzed in detail, and the design and implementation of thermal head overheat protection and stepper motor drive module are given.

It is mainly composed of a main control device, a stepper motor drive module, a thermal print head overheating protection module, a thermal print head paper shortage detection module and a power supply module. Among them, the stepper motor drive module is responsible for controlling the paper feeding and paper speed; the thermal print head overheat protection module prevents the thermal print head from being damaged due to excessive temperature; the thermal print head paper out detection circuit completes whether there is paper in the thermal print head Detection; the power supply module supplies power to the control circuit and thermal print head.

Asking for advice - Is there any cheaper core chip for designing GSM SMS transmitter besides Siemens TC35?
I think the TC35 has too many functions. I only need to send text messages, not voice or other functions.
Worried about switching from Class AB to Class D? No need to worry
Have you ever thought about doing something big and meaningful but worried that it would be hard to do? Then, when you finally get the courage to do it, you look back and are surprised at how easy it

My class project is stuck. I don't know what's wrong with the circuit diagram and program. Can you take a look?
Using DAC0832 to generate a sine waveform generator, the waveform cannot be designed. I don't know what is wrong. My circuit diagramProgram #include #include #define uchar unsigned char #define uint u
/*Urgent*/ AD issue
After AD conversion, we get 4 groups of word type AD values, which are stored in 4 arrays a0[8], a1[8], a2[8], and a3[8] respectively. Now we want to get the average value of a0[8], a1[8], a2[8], and
