Read-Only Author James Wilkinson Posted 3-May-2001 14:00 GMT Toolset C51	RE: Interface a assambler prog. in a C-Prog. James Wilkinson Search the knowledgebase for an example maybe? Read the C51 primer and/or the getting started and creating applications Attempt to code it and then ask for help when problems arise. There's a lot of information already on the keil site on this subject ( as its not exactly straightforward ), have you checked already?

Read-Only Author uu rt Posted 8-May-2001 09:46 GMT Toolset C51	RE: Interface a assambler prog. in a C-Prog. uu rt Out of curiosity, I found the answer to your question. Its easy, just dig the knowledge base.... QUESTION Is there an example of how to mix C and assembly? ANSWER The following example program shows you how to mix C and assembly in your 8051 programs. This example starts with a MAIN C function which calls a routine in assembly which then calls a C function. The MAIN C module appears as follows: extern void a_func (void); void main (void) { a_func (); } The function a_func is an assembly routine: NAME A_FUNC ?PR?a_func?A_FUNC SEGMENT CODE EXTRN CODE (c_func) PUBLIC a_func RSEG ?PR?a_func?A_FUNC a_func: USING 0 LCALL c_func RET END Note that this assembly routine calls c_func which is a C function: void c_func (void) { } The actual code for the assembly module was generated using the SRC pragma and the following C source file: extern void c_func (void); void a_func (void) { c_func (); } You may download C2ASM2C.ZIP from the Keil web site.

Read-Only Author Hans-Bernhard Broeker Posted 21-Jul-2003 12:16 GMT Toolset C51	RE: Interface a assambler prog. in a C-Prog. Hans-Bernhard Broeker How to insert asm code in c file. I don't want to generate asm file and not to call asm function. You've just said you want a recipe for making omelettes without breaking any eggs. The answer to that is the same as in the kitchen case: no way.

Read-Only Author Frank Hu Posted 21-Jul-2003 17:44 GMT Toolset C51	RE: Interface a assambler prog. in a C-Prog. Frank Hu Hi Changhua, You can use #pragma asm, #pragma endasm to insert pure asm code in your c code, and please don't forget to check the options of Assemble SRC file and Generate Assembler SRC file. But to me the best solution is to put the asm code into asm file, then you can avoid many headaches later. You will know what I mean when you go through it yourself. Hope it will help you out! Frank

Read-Only Author Andrew Neil Posted 3-May-2001 16:32 GMT Toolset C51	RE: Interface a assambler prog. in a C-Prog. Andrew Neil Of course, you have read the section "Interfacing C Programs to Assembler" in the manual, haven't you? Which bit was not clear to you? (You can open the manual by going to the 'Books' tab in the uVision Project window, and choosing "C51 User's Guide")
