uint32_t undefined

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

uVision puzzles me a fair bit.

Not really. It's the compiler, and more importantly, that code you're compiling with it, that does.

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

And who outside your workplace is supposed to know what those typedefs are?

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

What made you think it was supposed to be pre-defined? Where do you expect that definition to come from?

Ok I see I take things for granted here :)

I'm working with the uVision with an ST ARM eval board which you guys didn't know..so I see you point

I will direct the question to the ST forum (ST shares code exmples where they use the uint32_t type)!

Thanks for your reply

uint32_t should normally be defined in stdint.h - maybe you need to add a line:

#include <stdint.h<

early in your source file.

Another thing. #define SYMBOL RANDOM_RUBBISH will not produce any errors since #define is handled by the preprocessor. It isn't until you get the preprocessor to expand SYMBOL that the compiler will see RANDOM_RUBBISH and can generate a compilation error.

So a #define can contain undefined data types or variable names without any errors - unless you make use of the #defined symbol.
