It produces advanced delay sounds without an overcomplicated format. Wampler Ethereal Delay Pedal The Wampler Ethereal Delay Pedal is aesthetically pleasing and sonically satisfying.
#Best simple delay code
My whole point here is that accurately calculating how much time this code will actually take is difficult. Listed below are our Top 15 Best Delay Pedals for 2023: 1. Since the compiler decided to involve the stack, data caching could also play a part. Pipelining, branch prediction etc will mean that the code might execute faster than just the sum of the clock cycles though. If while the aforementioned delay was running, an interrupt occurred that required 100us to service, the pin would be pulsed high for 1.1ms rather than 1ms. solid workhorse simple delay for when you need something really quick and easy. They are far less useful, however, in contexts where other things may be going on. In these cases, a very short, usually single-tap delay can do the trick. For example ARM gcc -O3 -ffreestanding gives: dirty_delay:įrom there on you can in theory calculate how many ticks each instruction takes and change the magic number 50000 accordingly. Simple delay methods can be useful in such contexts.

This is guaranteed to generate various crap code.
#Best simple delay Patch
Its very simple to write your own patch that has a clean delay set in milliseconds, and nothing. For example: void dirty_delay (void)įor(volatile uint32_t i=0 i<50000u i++) If you can find a used Eventide DSP box, it could be ideal. If you want insist on generating a dirty busy-loop, then it is sufficient to just volatile qualify the loop iterator. Many architectures (like Cortex M, iirc) are free to skip NOP on the CPU level and actually not execute them. Using NOP instructions might not work.Toggling a GPIO pin repeatedly is a bad idea since this will draw current needlessly, and potentially also cause EMC issues if the pin is connected to traces.Optionally, you can even let the CPU sleep and use a wake-up interrupt.ĭirty "busy-delay" loops on the other hand, are rarely accurate and come with various problems such as "tight coupling" to a specific CPU instruction set and clock. These have the advantage that the timing is precise, deterministic and can be easily adapted if CPU clock speed is changed.
