stm32f10x_stdperiph_lib warning

In my IAR EWARM version 6.20 STM32 library, both stm32f10x_rcc.c and stm32f10x_dma.c have duplicate #define FLAG_Mask statements, producing a warning at compile time.

I redefined the RCC statement and its usage to RCC_FLAG_Mask and all is well. Redefining the DMA statement and all DMA usage to DMA_FLAG_Mask will reduce the probability of application code tripping on the same warning.

This probably occurs on other development IDEs as well.

Cheers, Hal

    I already have revision 43377 of intrinsics.h at that location. Your revision is 34635. Is there some reason to change to your revision ?

    My standard peripheral library version is 3.1.2. The ST web site now has version 3.5.0, and it also has the duplicate #defines. Since only a warning is produced, the code may execute OK, but even warnings should be fixed.

    ST-One - what say you ?
