Default Firmware B3

What's included in the "Firmware Update 3 for Buffalo-IIIse DAC" ? Is that located in IC8 and
if so, is it "plug and play" ? I have 3 Buffalo IIIse's that are approximatly three years old and
I have never updated any firmware on them.

Yes, IC8 is a micro-controller (ATTiny88) containing the firmware. Upgrading is simply replacing the chip. This is why we use a DIP-8 package with socket.

With regards to the firmware, unless you are trying to synchronously clock the DAC, or using the new Trident-SRs, there is no reason to upgrade. The main change in the firmware is an improved startup/initialization loop.

Hi Brian,

I am using the BIII in 8 channels configuration, now I do need to change the I2S format that is only possible on the BIII/SE.

Is possible to have a code that does permit this using differently the dip switches, or more simply to patch the controller code for have the I2S, or the left justified or the right justified?

Obviously I am not asking to have this for free.

Thanks and regards
Marco

I could create the firmware hex to do what you need very easily - do you have an AVR programmer - like an AVR Dragon?

What format are you looking for? What is the application?

I can flash and ship a chip as well once the firmware change is done if needed.

Thanks Russ, no problem I can buy one of it ...

I do need to have the possibility of try all the three I2S formats (I2S, I2S left justified and I2S right justified), because my multichannel USB to I2S interface doesn't work with the standard I2S format used in BIII, or better I was able to change the format using it in Windows XP and Windows 7 32 bit, but now I do need to use it in Windows 8.1 and Windows 10 at 64 bit and with these SO the drivers are locked ...

Obviously I can pay your disturb with Paypal.

Thanks also to Brian but I am in Italy and the post service is very slow near Christmas.

My email is microfast@tiscalinet.it

Kind regards
Marco

Just arrived the Atmel AVRDRAGON ...

I must wait from you a complete new firmware to flash or can I read, edit ( on your indication ) and flash again the modified firmware?

Thanks a lot

Marco

Will you ever need SPDIF input or mono mode?

Are you using the DAC in stereo mode wired like B3SE?

If you are using it in 8 channel mode I will need to remap some switches. If you use using it in stereo mode wired like a B3SE then you can just use the B3SE firmware as long as you are not using SPDIF. Just turn SPDIF detection off.

Thanks for the files ..

Yes, I am using my BIII in 8 channels and never will use SPDIF in this unit.

I will do know the results
