folowing is the code used to call function "function" from assembly but it gives error of undefined varibales EXTRN CODE (function)
EXTRN DATA (?function?BYTE)
EXTRN BIT (?function?BIT)
MOV R6,#HIGH intval
MOV R7,#LOW intval
MOV R7,#charconst Please use the 'PRE' and '/PRE' tags to format your code! See: http://www.8052.com/forum/read.phtml?id=120609 Exactly what symbols give you "undefined" errors? Are these Assembler errors, or Linker errors? As far as I can see in the code you presented, there are no definitions for intval, charconst, etc - which would obviously cause "undefined symbol" errors! When linking 'C' and assembler, all your public symbols must follow the C51 naming convention. http://www.keil.com/support/m...egname.htm Remember that 'C' is case sensitive... |
