Arduino UNO and UTFT Library

Projects Programming
1

I am trying to compile and upload the code in Arduino UNO board:

But I am getting below error. How do I solve this one:

Arduino: 1.5.6-r2 (Windows XP), Board: "Arduino Uno"

Sketch uses 39,418 bytes (122%) of program storage space. Maximum is 32,256 bytes.

Global variables use 370 bytes (18%) of dynamic memory, leaving 1,678 bytes for local variables. Maximum is 2,048 bytes.

processing.app.debug.RunnerException: Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.

Looks like you have two options: 1) find a way to recode the program to reduce the code size by more than 22% (in most cases, not easy), or 2) use an Arduino that has more memory (e.g., an ATMega2560).

Read Hennings documentation of UTFT lib. Electronics - Henning Karlsen
comment out parts (LCDs) you dont need (it will fit the UNO)

I tried commenting a lot of code but still I get the same issue .. the final hex file is just very large that only a small lines of code if compiled with UTFT library works .

..so you read the docs.. and found the file "memorysaver.h"
Comment out chipsets not relevant

Hi @prakash_prasad

Did you ever get this to work?
