I'm using the serial screen and Arduino UNO for my project. The serial screen has its own instruction set so there are a lot of long strings and I can't reduce them.
Here is my code:
unsigned int r_flag1 = 0;
uint8_t RecievedTemp1[30] = {0};uint8_t cout_i = 0;
unsigned int quan_hang1 = 0;
unsigned int quan_hang2 = 0;
unsigned int quan_hang3 = 0;
unsigned int quan_lie1 = 0;
unsigned int quan_lie2 = 0;
unsigned int quan_lie3 = 0;
unsigned int quan_zuoxia = 0;
unsigned int quan_youxia = 0;unsigned int cha_hang1 = 0;
unsigned int cha_hang2 = 0;
unsigned int cha_hang3 = 0;
unsigned int cha_lie1 = 0;
unsigned int cha_lie2 = 0;
unsigned int cha_lie3 = 0;
unsigned int cha_zuoxia = 0;
unsigned int cha_youxia = 0;
unsigned int cha[8]={0};
void setup()
{
Serial.begin(115200);
for(int i=3; i<=8; i++)
pinMode(i,OUTPUT);
}void loop(){
if(Serial.available() != 0)
{
// for(cout_i = 0; cout_i < 30; cout_i ++)
// {
// //RecievedTemp1[cout_i] = Serial.readBytes(RecievedTemp1, 15);
// Serial.readBytes(RecievedTemp1, 20);
// //Serial.println(RecievedTemp1[cout_i]);
// }
Serial.readBytes(RecievedTemp1, 20);
// for(cout_i = 0; cout_i < 19; cout_i ++)
// {
// Serial.println(RecievedTemp1[cout_i]);
// }
switch(RecievedTemp1[13])

using lot of Println will increase memory utilization. Use switch cases, maybe it will help, reduce the code.

Reduce usage of lots of variable, check if there are lots of serial print is used in the code which excedds the RAM.
