128 instruction/program * 4 bytes/instruction so 512 bytes per program Programs are sequential in the EEPROM so program 0 is bytes 0 -511, program 1 512 - 1023, etc. Yes, that is clear enough but is the reading method used by the FV-1 the sequential read described in the EEPROM datasheet? Or is it ...

Just reads the EEPROM exactly as shown in a datasheet for the 24LC32A. Programs are in the EEPROM in order so program 0 starts at address 0 of the EEPROM. Okay, would that be a sequential read as described in the datasheet? 8.3 Sequential Read Sequential reads are initiated in the same way as a ran...

Hi, I am wondering if there is any documentation of the I2C messages sent by the FV-1 to the EEProm chip for program loading. Like a description of what messages are sent out and what the FV-1 expects to get back, as well as a timing diagram if possible. Please let me know, thanks!

Hi, I switched display setups on my development machine and now the window showing build errors no longer appears when I build a SPINASM project. I've opened all the different menus available and none of them have any options related to this, all tried showing all windows and it doesn't appear the e...

The 512, 1024, 2048, 4096 amplitude coefficients make sense, but how does that amplitude map from the integer value in samples to a 0-1 floating point value in the accumulator? Looking for a precise way to scale this such that I have an exact 0-1 ramp wave value in the accumulator. Frequency makes s...

The programming manual directly states that Cho SOF can be used with a sine LFO. Is that a typo?

From the parameters section in the manual:

"LFO select: SIN0, SIN1, RMP0, RMP1"

Hi, I'm writing a granular / sample chopper program on the FV-1 where I'm using the built-in LFOs as a timing and enveloping element. Currently using sine since the documentation is clearer on how this works outside of the pitch shifting application described in AN-0001, but it seems like RAMP might...

Hi, I'm writing a granular / sample chopper program on the FV-1 where I'm using the built-in sine LFO as a timing and enveloping element. In the programming manual and AN-0001 it states that CHO SOF can be used to get a crossfade coefficient for a given LFO. It's pretty clear what this does for RAMP...

Hi I am writing a reverb program wherein I would like to be able to change the length of multiple delays to change the room size of the effect. I am wondering how to use the rmpa opcode to index multiple delay lines. It seems like it's set up to do one big block of delay memory, and isn't good for a...

Hi, I am currently analyzing a reverse delay program (found here, thanks forum user igorp: http://www.spinsemi.com/forum/viewtopic.php?f=3&t=10&start=30 ), and the question came up of how to translate hex values given as opcode arguments to more human readable decimal integers / floating poi...

Hi, I am working on a project building a custom test signal generator using the FV-1, I currently have it doing a variety of common waveforms, now looking into noise generation, specifically pink noise as that's a standard test signal in pro-audio environments. Just wanted to check whether or not th...
