FAQ of UART LCD Module
Why does P.BOX are priority to purchase?
No matter what size are you targeted in, Proculus (a reliable LCD module manufacturer) highly recommend customers put 2.8" P-Box Starter kits in the cart at the lowest cost to perform with your controller including all accessories that you need. Please read the following link for the starter kit:
How to use UnicView AD?
In the first step, the interface project is designed on UnicView AD software, by importing images, laying out the buttons and views visually, and configuring the LCM parameters. In the second step, the interface project is downloaded into the LCM. In the third step, the LCM is connected to the product's microcontroller, which exchanges data to and from the LCM.
Is Software UnicView AD® free of charge?
For first-time users, we offer a valid-15days free serial key since the pack's arrival to evaluate. If you need more time to test, $100 USD would be charged however it going to be refunded on premise that the product step into production.
How to test the sample of UARTs ?
Please go to web to understand more.
How simple is UnicView AD?
UnicView AD is so simple that it can be used to create very complex interfaces, like multi-parameter monitors, in just a few hours (for medium-experience developers).
What is RS232?
RS232 is a serial communication interface standard issued by the American Electronics Industry Association in 1962. RS is the abbreviation of "Recommend Standard" in English, and 232 is the identification number. The standard specifies the physical interface and logic level of serial communication. The output level is called the RS232 level.
The simplest RS232 communication consists of three data lines, namely TxD, RxD, and GND. RS232 uses negative logic levels, that is, -15V ~ -3V represents logic "1", and +3V ~ +15V represents logic "0". The level here is the voltage of the TxD line (or RxD line) relative to GND.
It can be seen that TTL level and RS232 level are different in voltage range and polarity (RS232 negative logic level). Therefore, these two-level interfaces cannot be directly connected.
In order to convert the TTL level of the MCU to the RS232 level, we usually need a special conversion chip.
What is TTL?
TTL level is the output level of the TTL circuit, where "TTL" is the abbreviation of "Transistor-Transistor Logic".
Since the level is a continuously changing voltage range, in order to use this analog voltage to represent the logic 1 and logic 0 of the digital quantity, the TTL level stipulates:
Output circuit: voltage greater than or equal to (≥) 2.4V is logic 1; voltage less than or equal to (≤) 0.4V is logic 0;
Input circuit: voltage greater than or equal to (≥) 2.0V is logic 1; voltage less than or equal to (≤) 0.8V is logic 0.
What is Uart LCDDisplay?
Universal Asynchronous Receiver Transmitter, usually called UART. In an embedded system, it is usually used as a peripheral of the MCU. In general, the TTL level is directly derived from the chip pins. If there is a conversion chip connected to the UART, it may be RS232 level.
What is RS485?
RS485, also known as TIA485(-A) or EIA485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems.
The RS485 differential line consists of two signals: A, which is low for logic 1, and high for logic 0; B, which is high for logic 1 and low for logic 0.
