Delay component
Allows an adjustable delay to be inserted into the DSP system
Examples
Here is a simple example file for the Delay component.
Delay
The DelayADC component is used to set the amount of delay that the component provides 0-2550 samples in steps of 10 samples.
The Input ADC component is used to pass a variable value into the DSP chain to allow the delay to be simulated.
Here is a picture showing the scope response of the delay component.
Note: 8-bit PICs can only reference an array of up to 256 elements. Anything more then this will cause compilation errors. There is a workaround documented on the user forums on how to get around this limitation but it adds overhead to the rest of the program.
Downloadable macro reference
DelayTick
Passes a single value from a buffer into the delay buffer and spits out a delayed value at the other end
Parameters
- This macro has no parameters
Return value
- This call does not return a value
Delay
Passes an entire buffer into the delay buffer and spits out a delayed version of the buffer at the other end
Parameters
- This macro has no parameters
Return value
- This call does not return a value
SetDelaySize
Specifies the number of values in the delay buffer to allow the length of the delay to be adjustable during runtime.
Parameters
- UINT Delay_Count
Return value
- This call does not return a value
Simulation macro reference
This component does not contain any simulation macros
