Brief Introduction
Thermal printers are very common in our daily life, and there are examples of thermal printers in restaurants, parking lots and shopping. This article will focus on the application of thermal printers in parking systems.
Materials To Be Used
- STONE STWI101WT-01
- FTP thermal printer head
- Raspberry Pi pico
- Coin-operated machine
Function
The control function is displayed on the serial screen, the main interface selects the floor, after entering the main interface selects the parking space, at the same time it will display the parking space number in the text box on the top right, then selects the stay time, it is two scrolling text selectors, then also the same will display the order information in the text box on the top right, according to the fixed unit price which multiplies with the stay time to get the total price. Then only when the parking space and the stay time are selected, you can go to the payment button, otherwise, it is invalid. After entering the payment screen, a coin acceptor will be used. Then the screen will show the number of coins to be put in and the number of coins already put in. After the coins have been put in, a payment success message will be displayed. Then you can choose to print a small ticket to print the place number and time on the thermal paper.
The Design Process
At first, I wanted to use the Raspberry Pi pico to make a small printer. Then in the process of selecting components, I think the thermal printer is more convenient to achieve, after determining the program, I began to purchase hardware. In fact, in the process of online procurement, I found that there are many thermal printers with good driver circuits, most of them are made by using STM’s chip, and they are designed with their own set of instructions. For example, by using his instructions to let the printer print characters or go paper, but this printer’s practicality is very high, but there is no value in learning. It is to send instructions through the serial port on the line, you can manipulate the printer. So I thought I’d buy a print head and develop it myself. Then about the print head, I chose an FTP thermal print head.
