I am working with mixed programming logic of Inline Assembly and C to code a CortexM3 (STM32F103ZE form ST microelectronics) processor using Keil IDE.
The board is from Keil.
The problem is how to access particular memory locations and registers in C. And hence I am unable to pass the data for Assembly Coding.
We can think in terms of pointers and Memory maps.
Rxx registers should not be used for passing information between different codebases. ANSI C standard does not alllow such low-level operations and may generate code that overwrite such registers. You should consider access memory area directly instead by casting an address into a C variable.
volatile unsigned char *onebyte = (0x10000000); // look at memory address 0x10000000 as one byte data
Additional macro for Cortex-M3 are located in header files at Keil\ARM\CMSIS\Include folder.
