Macro reference
EndOfFile
|
EndOfFile |
| A simple check to see if we are at the end of the file. Returns 0 if we and not yet at the end fo the file. Returns 1 if we are at the end of the file. | |
 - BOOL
|
Return |
GetBitsPerSample
|
|
GetBitsPerSample |
| Returns the number of bits per sample. | |
 - BYTE
|
Return |
GetNextSample
|
|
GetNextSample |
| Retreives the value for the next sample and auto increments the file pointer. Ideally this function should be called as part of a timer interrupt at the sample rate. The value returned should be passed onto a means of analogue output e.g. a DAC or PWM. | |
 - UINT
|
Return |
GetNumChannels
|
|
GetNumChannels |
| Returns the number of audio channels stored in the WAV file. | |
| - BYTE
|
Return |
SetFilePointer
|
|
SetFilePointer |
| Allows direct control of the file pointer. Write the file pointer to 0 to reset the pointer to the beginning of the file. Write the file pointer to 0xFFFFFFFF to force the pointer to the end of the file. | |
 - ULONG
|
Pointer |
| Range: 0x0 to 0xFFFFFFFF, 0 = Beginning of file | |
 - VOID
|
Return |
Property reference
|
Properties |
|
WAV File |
| WAV File to Embed into the ROM Flash memory. | |
|
File Status |
| Displays diagnostic data about the selected file. | |
|
Num Channels |
| Number of audio channels encoded in the WAV file. 1 indicates a MONO audio stream. 2 indicates a STEREO autio stream. | |
|
|
Sample Rate |
| The rate in samples per second at which the WAV file was recorded. | |
|
|
Bits Per Sample |
| The number of bits used to store a single sample. | |
|
|
Byte Rate |
| The number of data bytes per second that need to be processed in order to maintain playback. | |
|
|
ROM Bytes |
| Number of bytes of ROM that will be required to store the WAV file. | |
