hw_types.h

从Luminary官方网站下载的LM3S6000系列的UCos+Tcp/IP的源码, 经本人稍微修改后可直接在IAR6.2下编译通过,里面包括了LM3S6000系列的所有外设UART, PWn....

//
// Helper Macros for determining silicon revisions, etc.
//
// These macros will be used by Driverlib at "run-time" to create necessary
// conditional code blocks that will allow a single version of the Driverlib
// "binary" code to support multiple(all) Stellaris silicon revisions.
//
// It is expected that these macros will be used inside of a standard 'C' 
// conditional block of code, e.g.
//
//     if(IS_BASE0_REVC1())
//     {
//         do some REV C1 specific things here
//     }
//
// By default, these macros will be defined as run-time checks of the
// appropriate register(s) to allow creation of run-time conditional code
// blocks for a common DriverLib across the entire Stellaris family.
//
// However, if code-space optimization is required, these macros can be "hard-
// coded" for a specific version of Stellaris silicon.  Many compilers will
// then detect the "hard-coded" conditionals, and appropriately optimize the
// code blocks, eliminating any "unreachable" code.  This would result in 
// a smaller Driverlib, thus producing a smaller final application size, but
// at the cost of limiting the Driverlib binary to a specific Stellaris
// silicon revision.
