Electronic – STM32 and uCOS+uGUI

armmicrocontroller

  1. Can I use STM32F103VCT6 with uCOSII2.91 and uCGUI3.90A ?
    Because from datasheet I saw the flash memory of STM32F103VCT6 is 256Kb
    and the result of compiling uCOSII2.91 and uCGUI3.90A is 689K
    I'm using Keil4 for compiling uCOSII and uCGUI.

  2. If I want to update or customize the display on LCD,
    The step that I must take :

    1. Modify uCOSII and uCGUI
    2. Compile them
    3. Upload to hardware using JLink,

Am I doing the right step ?

You are showing us the size of the hex file on your development machine's disk, rather than the size of the binary image it represents. It is the latter which must fit in flash memory.

As a hex file is a printable ASCII representation, and has addresses, byte counts, and checksums per line, it is going to be on the order of 2.5-3x the size of the image it represents.

Also, you may not have set your toolchain to strip unused code. For example, in a gcc-based toolchain you would specify --gc-sections to the linker.
