Nava Sequence won't advance.
Posted: Sep 13th, '21, 03:26
I turn it on and hit start, but the sequencer won't advance.
I've reflowed the IC a few times and have reprogrammed it a few times, but no change.
Enter the world of easy DIY

So while I am programming a pattern it will suddenly become length of 256, scl of 0, and all instruments on accent high for each step. Patterns are not saving properly.
If I program last step to 16, it will be after the 16th step when it resets.
I swapped the EEprom with the one from my working Nava and nothing changed.e-licktronic wrote:-Check that EEprom is well powered.AbeLovesSynths wrote:For some reason pattern is defaulting/overwriting to length of 256, scl of 0, and all instruments on accent high for each step.

-Check R689 R690 Resistor value on the I2C bus. Should be 4K7
-Check that they are well connected to +5V
-Try to replace your EEprom
I did that:e-licktronic wrote:Try to swap your working uC with the one on the Nava that doesn't
What you swap it is the microcontroller Atmega1284p what you need to swap is the small DIP8 I2C EEprom IC115 not IC119AbeLovesSynths wrote:I did that:e-licktronic wrote:Try to swap your working uC with the one on the Nava that doesn't
I swapped the EEprom with the one from my working Nava and nothing changed.
I put the EEprom from the Bad Nava into the working Nava and it works just fine.
So it's not the EEprom right?
Ok my bad.
