After the software is successfully linked, the current wave rate will be displayed in the upper left corner.
3. Before modifying, you need to cancel the default configuration, click "Unconfigure the system", and the command assistant will send the corresponding command. The factory baud rate of nano serial port screen is 115200, and the factory baud rate of other models of serial port screen is 19200.
4. Modify the baud rate, the baud rate can be modified in the range of 1200-2000000, click " " to select the corresponding baud rate, and click "settings". For example, if you select baud rate 19200, click "Settings", and the command assistant will send the corresponding command.
5. If you need to re-lock, click "Lock System Configuration".
6. Re-online, the baud rate at this time is 19200.

Anonymous users2024-02-12In serial communication, the sender and receiver agree on the rate at which data is sent or received. The serial port of the microcontroller can be programmed into four working modes through the software, wherein the baud rate of mode 0 and mode 2 is fixed, and the baud rate of mode 1 and mode 3 is variable, which is determined by the overflow rate of timer t1.

Anonymous users2024-02-10The P3 port of the single-chip microcomputer 80C51 is connected to the RXD (serial data reception) and TXD (serial data transmission) of the serial port respectively. Due to the different protocol standards of the physical layer, it cannot be connected to the computer itself to communicate, but it can be connected to the computer through the conversion chip to other interfaces, such as RS232 port (the COM port of the computer).

Initialize three interrupts, x0 x1 t2.
T2 is started by x0 to send serial data at regular intervals and in cycles; >>>More
A: The bit-addressing area is located between 20F and 2Fh in the data memory. The registers in this interval can be bit-addressed, and they can be bit-manipulated and bit-arithmetic. >>>More
There is a problem with the visual inspection of the LCD program, not the driving aspect Yes"Data Processing"。Give you a direction, take a good look for yourself.
You can use the 12864 LCD module, the number of display lines is 4 lines, 8 Chinese characters per line, the voltage is also 5V, the backlight is green, and it supports parallel and serial two-clock data bus format You searched a lot of information on the previous one, and my space** is a 12864 do
I think my board is good, isn't it very shameless.
