Basic chip adhesive removal station

Overview

I. Team Introduction:
Electronics enthusiasts
II. Design Summary:
51 microcontroller collects real-time temperature data from the heating plate; PWM controls heating.
III. Design Concept:
Thermistor collects real-time temperature data; PID algorithm is used to adjust the target temperature.
IV. Hardware Circuit Composition

V. Program Flowchart

VI. Physical Demonstration

VII. Demo Video

VIII. Problems:

This is my first time using PID; I'm unsure if it's a programming or debugging issue. The temperature is unstable, and
sometimes there are accidental button triggers even after the button has been pulled down. Parallel debouncing capacitors don't work during testing. I don't know why; seeking expert guidance.

IX. Attachment:
Keil 5 source code

Simple transplantation of printf function of msp430
In the past few months, I have been working on a project of RGB color sensor based on TCS34725. The main control I use is MSP430. When debugging, I usually use 485 bus to send to the upper computer (c
Performance advantages of silicon carbide devices in switching power converters
[i=s]This post was last edited by qwqwqw2088 on 2020-12-20 16:16[/i]Introduction Over the past few decades, the semiconductor industry has taken many steps to improve silicon-based MOSFETs (parasitic
Which pins of CC2640R2F can output PWM waves
I feel that the definitions in the official manual are a bit simple, and I don't understand which ones can be used for PWM output. Does anyone know?
Please provide a C program to use msp430 to realize ultrasonic ranging
As the title says~~~~~~ I am currently researching ultrasonic ranging. . . I am looking for a C program to study. I am a novice. Please give me some advice~~~~~~
Will the hidden sectors of a USB drive be modified when formatting it?
My USB drive is 250M. I found 32 hidden sectors by reading BootSector. Will formatting the USB drive cause these hidden sectors to be overwritten? I want to put some of my own data in it. How can I re
Anyone who knows MCU or VHDL can help me, urgent! urgent! urgent! Waiting online
The programming implementation has an external interrupt source connected to the INTO terminal. When there is a terminal request, the CPU is required to transfer the data of the internal RAM 30H unit
