Environment: Arm Cortex processor STM32F103ZET6, on eval board Open103Z, Keil IDE, Windows 7.
in file stm32f10x.h there are a set of options defines that begin with:
#if !defined (STM32F10X_LD) && <and seven more is phrases>
...
/* #define STM32F10X_MD_VL */ /*!< STM32F10X_MD_VL: STM32 Medium density Value Line devices */
#define STM32F10X_HD /*!< STM32F10X_HD: STM32 High density devices */
...
I enabled the line shown. Several of the lines differ only in that one has "value line" and the other does not. What does "value line" mean?
