Re: Memory Address Interpolation Resolution
Hey! :D Yes I'm aware of these links. What I'm trying to do here is increase the interpolation resolution further beyond what is done automatically: 256 steps with the servo technique (RMPA). Similar to the equation in the link you posted the crossmix of the two RMPA readings form an additional 5-bi...

Memory Address Interpolation Resolution
Ignoring the SIN0/1 functioncs and the CHO instructions as an option. Is there any practical way of implementing an increased interpolation resolution from the 256 positions available with the RMPA-instruction (and ADDR_PTR)? This could be very useful for performing vibrato on shorter buffer segment...

Re: Program load time
Thank you Frank. So for external EEPROM it will take longer than internal. That makes sense I guess.

Program load time
Hi
Are there any numbers on how long it takes the FV1 to start executing the first program cycle when changing between programs?
Thanks

Harmful clipping?
I have a hardware setup where the FV-1 is connected to a attiny84 (t84) microcontroller. They are both powered by the same 3.3V power supply. I'm inputting a PWM stream from the t84 to ADCR on the FV-1 via the RC network proposed by the FV1 datasheet (page 5, link below). This causes the 'clip' LED ...

Re: "...directory\MFC363A.tmp contains an invalid path"
Changing directories did the trick! Thank you so much Frank for always answering so quickly!

Re: "...directory\MFC363A.tmp contains an invalid path"
Thanks Frank I'll give this a go! I'll try changing directory for the hexout, projects and programs. Do I also need to change the output directory for the "C header out" or are those files of no consequence?

Re: Alternate Assembler
This looks very interesting. I've been having issues with SpinAsm recently and will check this out as soon as possible. Is it possible to compile projects and build .hex files the same way as with SpinAsm IDE or will I need to know Python to operate the IDE?

"...directory\MFC363A.tmp contains an invalid path"
I recently started getting this error when attempting to save .spn files in subfolders of the spinsrc directory. There seem to be no issue when editing files directly in the spinsrc directory (the root directory). The error pop-up is followed by another pop-up stating: "Error Saving ... directo...

Accumulator clipping order question
Consider a single run-through of the below codes: sof 0, -0.5 wrax reg0, 0 ; reg0 = -0.5 sof 0, -1 wrax reg1,0 ; reg1 = -1 ldax reg0 ; acc = -0.5 rdax reg1, -2 ; acc = -0.5 + (reg1*-2) wrax reg2, 0 ; reg2 = acc What would be the content of reg2? On one hand you could think that -0.5 + (-1*-2) = 1.5 ...

Re: SMD Crystal oscillator
Yeah I've done some looking around and the cylinder is much cheaper. Wonder why..
The reason I ask is that I'm looking to have my boards with all components PCBA assembled at a boardhouse.

SMD Crystal oscillator
Does anyone have a recommendation for a 32768Hz SMD package crystal for clocking the FV1? Any special reason to use the cylinder style crystal?
