STC8A8K64D4 LCM_DMA开发板

简介:为了测试STC8A8K64D4的LCM_DMA功能,单独画了块板子
STC8A8K64D4 seems to be STC's first MCU to support LCD_DMA function, so I drew a separate development board. The board size was originally drawn according to TK032RB422 (made by Tiky), but I didn’t understand the LG4573A driver IC, so I used the code written by their other 5-inch ILI9806G driver screen.
Has anyone studied the LG4573A IC? I would be very grateful if you could give me a C51 routine reference. For the time being, the code only runs through the basic LCM_DMA function, plus a font call.
See the code: https://github.com/XanaduNWH/8051/tree/main/STC8A8K64D4/Tiky_LCD_TEST_board The STC official website provides software library functions and application examples, but the naming of DMA still uses the pre-update BMM, and in some places and the new version of the header file It's still not correct, so I don't use the official function library.
 
The layout of the PCB board is very unprofessional, I hope someone can give me some guidance.
 
[ChangeLog]
2022/03/29
Corrected the buzzer circuit transistor wiring error
2022/03/25
Updated the GT30L32S4W packaging error;
exchange P54 and P55, P54 is changed to a button and a current limiting resistor is added, and P55 is changed to a pinout ;
Exchange P37 and P42, P37 (INT4) is changed to pinout, and P42 is changed to button; the download circuit made of CH340C used in
 
the power supply + download circuit
board is more expensive than CH340G, but there is less crystal oscillator on the circuit. If the automatic download fails using the TYPE-C interface for unified power supply
, you can increase C7 for better results.
CH340C uses USB direct power supply, and the whole version uses AMS1117 to step down to 3.3 power supply. The extension leads to a 5V power interface.
 
The LED circuit
board carries two IO-controlled LEDs, and P11 is the output port of the hardware PWM1_2.
 
Button circuits
P33 and P37 correspond to INT1 and INT3. INT0 gives the touch screen interrupt.
P51 is an ordinary IO button;
P54 is the NRST pin, although by default this pin is used as a standard IO;
 
the expansion interface
H1 is the hardware LCM_DMA channel corresponding to the LCD screen interface pin. (LCMIFCPS[1:0] = 00; LCMIFDPS[1:0] = 00;);
There are D16~D23 on the silk screen, but the pins are not wired because the MCU's LCM_DMA function only supports 16-bit width.
BL is directly connected to P1.0;
the screen touch interrupt is connected to P32 (INT0);
CN1 leads to the hardware SPI interface (P_SW1 = 0x00), sbit ex_cs = P1^2;
CN2 leads to the hardware I2C interface (P_SW2 = 0x00);
CN3 leads to UART4 (P_SW2 = 0x04);
CN4 leads to P6, which is the interface of PWM*_3;
CN5 is some IO that has nowhere to be placed;
CN6~8 is the 3V3 power interface;
 
the font chip
GT30L32S4W chip
provides 12, 16, 24, and 32 dot matrix size GB2312 characters, 4 sizes of GB extended characters, multiple ASCII character sets.
SPI interface (P_SW1 = 0x00)
sbit zk_cs = P1^7;
 
Flash chip
W25Q64
SPI interface (P_SW1 = 0x00)
sbit flash_cs = P1^6;
 
EEPROM chip
AT24C128N
I2C interface (P_SW2 = 0x00)
 
Clock chip
DS3231
I2C interface (P_SW2 = 0x00 )
INT/SQW = P3^6;
 
Miscellaneous
A CR1220 battery holder, retaining the traditional VRTG4 line download interface.

TM1650 based clock

Introduction: I originally wanted to use TM1650 to light up a digital tube, but ended up making it into a clock.
The package size is convenient for manual soldering. 
There are three PCB prints, the mini one has a 0.56-inch digital tube, the 0.8 one has a 0.8-inch digital tube, and the other one is a draft, the size is weird and can be ignored.  
The code and project introduction are all on Github  
https://github.com/XanaduNWH/8051/tree/main/STC8G1K/CLOCK
 
Updated on 2022/03/18
The 12-pin digital tube with a colon point seems to have a decimal point that does not light up, no Do you know if all 12-pin ones are like this?
When placed together with the Mijia Bluetooth Thermohumidity Meter 2, the difference is about 2 degrees.
Update MenuIndex to PageIndex, and adjust the usage
to read the DS3231 internal temperature register and display it.

Introduction: This clock is made with Xianyu 1.2 yuan VFD screen.
The clock is made with a Xianyu 1.2 yuan VFD screen and uses the 8266 module to obtain the network time. It does not use a clock chip and automatically obtains the network time every 300 seconds. The program is poorly written and is for reference only. The first version in the video uses three 595 driver segments and bits. Q communication group: 513391

2022 China Jiliang University Lichuang Cup Title A Signal Hybrid Transmission System

Introduction: Infrared optical communication is used to realize mixed transmission of digital and analog signals. While signal demodulation is achieved at the receiving end, signal integrity is retained as much as possible and noise interference is reduced.
The transmitting end avoids signal interference and adopts synchronous and independent transmission;
the receiving end mainly uses a multi-order filter circuit to demodulate the two-way signals. After demodulation, the signal is restored through amplification, filtering, and envelope detection circuits;
the relay point mainly To achieve reception and retransmission, in order to retain the integrity of the signal, the relay point undergoes two-stage amplification. In order to reduce the operating current of the relay point, filtering is performed at the receiving end;
while ensuring the integrity of digital signal transmission, a Bluetooth module is added Implemented mobile display of temperature.
