Help code modification, so that LCD12864 can display Chinese [Copy link]

 

I am a newbie. I have an LCD12864 screen with fonts, connected to ESP32 and DHT11, which can display temp, humi and their values normally.
Now I want to change the first line of characters on the screen to the Chinese characters "四川成都", and change "temp" and "humi" to the Chinese characters "温度" and "幽默" respectively, but I don't know how to modify them.
I attach the code for help. I hope experts can give me some advice. Thank you!

from machine import Pin
import time
from dht import DHT11
dht11=DHT11(Pin(27))
cs = Pin(12,Pin.OUT) # LCD12864 uses the serial data transmission method
sid = Pin(18,Pin.OUT)
clk = Pin(19,Pin.OUT)
psb = Pin(13,Pin.OUT)
def Lcd12864_Write_Byte(byte):
cs.value(1)
for i in range(0,8,1):
sid.value(1 if( byte<<i)&0x80 else 0)
clk.value(0)
clk.value(1)
cs.value(0)
def Lcd12864_Write(cmd,data):
Lcd12864_Write_Byte(cmd)
Lcd12864_Write_Byte(data&0xf0)
Lcd12864_Write_Byte((data<<4)&0xf0)
def Lcd12864_Init():
psb.value(0)
Lcd12864_Write(0xf8,0x30)
Lcd12864_Write(0xf8,0x06)
Lcd12864_Write(0xf8,0x0c) Lcd1286
4_Write(0xf8,0x01)
Lcd12864_Write(0xf8,0x80 )
def Lcd12864_Write_Text(addr,data):
Lcd12864_Write(0xf8,addr)
for i in range(len(data)):
Lcd12864_Write(0xfa,ord(data[i]))
def DHT11_Read_Data():
time.sleep(1)
dht11.measure()
temp = dht11.temperature()
humi = dht11.humidity()
Lcd12864_Write_Text(0x88,str("humi = %d%%"%humi))
Lcd12864_Write_Text(0x98,str(" temp = %.1f"%temp))
time.sleep(2)
def main():
Lcd12864_Init()
Lcd12864_Write_Text(0x81,str("SC_CD_ZZ_XXX"))
Lcd12864_Write_Text(0x90,str("-------- --------"))
while True:
DHT11_Read_Data()
if __name__ == "__main__":
main()

It is recommended to send back a single Chinese character. Don't think you can send a string of Chinese characters or phrases. It will be very troublesome!

If you need to use it universally, you need a character library, and use it to get the Chinese character dot matrix for display. If you only need a few Chinese characters, you can first take the modulus and store it in a file or array.

Use Chinese characters to take the modulus and then send it.

Doing it yourself is just taking the model, after all, there are not many words

If it comes with a font library, you can look for examples of displaying Chinese characters and you will know how to use it.

Take replacing "temp" with the Chinese character "温度" as an example, how do we modify the original code? Please give me detailed advice from the moderator and other experts, thank you!
