#65453 - Why the Data Sheet says it Responding to: ???'s previous message |
Gerard Akse said:
As you can read in the chapter you're referring to only ASSEMBLER COMMANDS are given to read an input pin or (re)set an output pin. That is because that's all the processor understands, and that is the only thing they can say without being specific to any particular vendor, tool, version, etc Gerard Akse said:
They are of no use to me as I'm programming in a ANSI C compiler. As mentioned elsewhere, there is nothing in ANSI 'C' to help you here at all - this can only be handled by compiler-specific extensions to the language. The datasheet writers couldn't possibly go trawling though every possible 8051 'C' compiler manual to list out every possible syntax variation - that's why they have to stick to the processor's own, native instruction set. And that's why you also need at least a passing acquaintance with the 8051 Instruction Set: http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf |
