UINT8 TMR0
PostPosted: Fri Apr 28, 2006 6:03 am     Reply with quote
UINT8 TMR0;
UINT8 STATUS;

I saw these lines in a sample code. I don't understand what is it mean?
Is UINT8 a keyword?

Thanks for your help.

UINT8 TMR0;
It is a Data type Specifier and it makes reference to an Unsigned 8 bit INTeger.
(Not applicable to CCS)
For CCS it is not a keyword, surelly another compiler use that notation.

I use that. It is just a typedef. I like to do this in a stdint.h file. It makes porting code much easier since compilers treat 'int' differently. I have since changed to using 'uint8_t'

Code:

// Defines the standard integer types that are used in code
// for the Microchip microprocessor.

#ifndef STDINT_H
#define STDINT_H

typedef unsigned char       bool;
typedef unsigned char       uint8_t;   // 1 byte  0 to 255
typedef signed char         int8_t;    // 1 byte -127 to 127
typedef unsigned int16      uint16_t;  // 2 bytes 0 to 65535
typedef signed int16        int16_t;   // 2 bytes -32767 to 32767
typedef unsigned int32      uint32_t;  // 4 bytes 0 to 4294967295
typedef signed int32        int32_t;   // 4 bytes -2147483647 to 2147483647

union wide_data_t
{
  uint8_t byte[2];
  uint16_t word;
};

#endif // STDINT_H
