log.c
log.hCode:#include <types.h> #include <log.h> int log(int constant,void *value,int len) { dprintf("log(%d,%x,%d)\n\r",constant,value,len); return 0; }
how do I write a test function for RES????Code:#include <types.h> #include <imaging.h> #ifndef h_log #define h_log #define RES 8 int log(int constant,void *value,int len);

What do you think "writ[ing] a test function for RES" even means? It's a constant.
okay, ma fault.
how do I initiate the dprintfs?? it's a constant that can be passed to the int log ()
So now, what does "initiate the dprintfs" mean? If you want to use RES in a function call, then do so:
Code:log(RES, some_ptr, some_int);
the program would watch for RES to change - if it changes to +2
- do some calculations
- pass it as a pointer
- assign a length to the value and write to some memory address
RES can't change. It's a constant.
First of all is your constant defined variable RES to be used in your log()? Are you including many other .h files which may or may not have #define RES /*some number */ ? You may then need to check, like you did for h_log, whether RES is defined. If this is to change you will need to use #undef, then re-define your RES constant. With your questioning, you left more questions than can be answered up for.
Well, if you dont explain what excatly you want and what your actually after with the code, you wouldn't get any help. You hardly provide any information there.

I am trying to write a function will utilize the (constant, *value, len) as input parameters
where do I start???
What do you mean "utilize" them? What do you want this function to actually do?Originally Posted by tingting
The code you have already utilizes the constant, *value, and len as input parameters, as it needs them for the print statement. So I guess you're done.
tabstop,
for me to log anything to flash log section,
- i need to test a condition whether it's been triggered, then in main.c, I need to call the initialization function to execute the log

Why don't you post a stripped down example program of what you're trying to do?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
This is just getting so funny. Why don’t just copy and paste a few bits of code here if you don’t want to say what you’re trying to do. It makes our life much easier at least.
