Hi ,im from China. Now i need some help ! sry,my english is terrible. It maybe ambiguous.
im just a arduino freshman. I only know a litte about it.
i want to display some system info ,such as cpu usage ,temp ,sda temp,menory freee on arduino lcd.
you can understand it as a monitor , oh it’s surely a monitor
On ubuntu ,using python serial writes strings to arduino.
with the problem coming ,i find ,the lcd can’t show all information because ,the info i need exceed what
lcd can display. i dont know how to describe it,which makes me go crazy!
for example ,15 lines infomoration should be writen to arduino and display it . But the lcd only display
10 lines(maxium ,font is small ) . And the remainder 5 lines cover the first 5 lines
I want to clear oled,display 10 lines eralier and the last 5 lines display on a new lcd .
so that i can reach a “roll” design. here is my arduino code
String comdata = “”;
while (Serial.available()> 0)
comdata += char(Serial.read());
if (comdata.length() > 0)
comdata = “”;
what should i do to modify or add code . Thanks
