hello,   

      How to create a 2D array of size array[10000][10000]. I am getting the following error

          unable to allocate space for sections/blocks with a total estimated minimum size of 0x66d14 bytes in <[0x20000000-0x20020000]> (total uncommitted space  .

Thanks

    No kidding, the part you're using doesn't have 100MB of space to give you.

    Thanks Clive for the prompt reply. 

    One more Question how would I update the .DMA_BufferSize resistor as I update the PWM value by modifying the TIMx->CCRx resistor.

    Thanks Again.

    I don't really understand the question, you can DMA_DeInit()/DMA_Init() to reconfigure a DMA transfer.

    ''how would I update the .DMA_BufferSize resistor (sic) as I update the PWM value by modifying the TIMx->CCRx resistor (sic)''

    I think you mean re

    g

    ist

    e

    r?

    These are resistors:

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Sorry for the trouble, I figured that out. 

    Also one more thing I want to communicate to the terminal through USB, Do u have a sample code. I am using the STM32F4 discovery board.

    Thanks again...

    I did port the VCP example to the STM32F4-DISCO
