uint32_t undefined

Thomas S

uVision puzzles me a fair bit.

In my project I have declared instances of TIM_TimeBaseInitTypeDef, RCC_ClocksTypeDef, I2S_InitTypeDef without any problems.

Now I'm trying to declare an instance of DMA_InitTypeDef and get this error:

main.c(460): error: #20: identifier "uint32_t" is undefined

I am able to define the following:

#define ADC1_DR_Address ((uint32_t)0x4001244C)

which doesn't give me an error.

this is wierd so any advice?

The newbie

    sorry it was the

    DMA_InitStructure.DMA_PeripheralBaseAddr = ADC1_DR_Address;

    where ADC1_DR_Address is defined as

    #define ADC1_DR_Address ((uint32_t)0x4001244C)

    that caused the trouble.

    I'll try to continue changing it to:

    #define ADC1_DR_Address ((uint32)0x4001244C)

    Can someone please elaborate on the differenc?

    Thanks
    Thomas
