I REALLY wish people would start a new thread rather than hijack an existing one, much easier for others to find it based on the topic and for me to find it and try to help.

Make sure the SpinAsm d ...

Could you link to the datasheet from the Citizen crystal you are using? I'd like to compare the specs with the Auris crystals. I've ordered a no-clean flux pen and a complimentary flux removal pen. Lo ...

Honestly the best thing is to remove all components and clean everything or start with a new board and abandon these ones. You will not be able to clean under the chip and other components unless you ...

Crystals are a very finicky device and different ones can have different requirements. Stick with one model, we use Citizen and have had good results. Only get parts from a known good supplier, discou ...

1. No address is fixed and cannot be changed.

2. Programs are linear in the EEPROM, i.e. program 0 starts are address 0 and continues for 512 bytes (0 - 511), program 1 starts at 512, etc.

You can make any changes as required for your use but be aware that the DAC is a sigma-delta so it will require some low pass filtering to remove the out of band noise.

Check the voltage levels at the S pins to see if they are getting the proper level, if they are not then back track from the pin to see where the issue is. I would guess that S1 is not seeing the prop ...

Indicates an issue with the soldering of the FV-1, reflow the pins and make sure to clean any flux residue from the board.

All I can suggest then is you check your board and make sure the POTs are working properly.
