Thanks DQ828, I received the files and tested, but no success.

I think the problem is related to the file structure in the SD. Thanks a lot for your help and effort.

Hi bigpandahk. I've been following your progress (along with DQ828 and Corpius). I have a dual mono BIII with 4 input S/PDIF board and Sidecar mostly complete (want to add USB input). I was designing a case when I saw the Arduino with LCD displays and had to have one...hopefully...lol

Hi SCompRacer

I am also following your BIII project and your connection to the DVD player is great. I will use OTTO 2 and teleporter to connect a DSD sourse and is searching a suitable DVD player.

Hi DQ828

Finally, I manage to display the Bitmap files. The problem is the SD card must not be a MicroSD with adaptor. I hardly find an old SD card and have your bitmaps displayed on the GLCD.

Thanks again for your help and efforts.

This project is far complicate than expected. Just find the best way to connect all the modules is not easy. Thanks for Ian's I2S backdoor which make my life much easier.

I still can't figure out how to switch between PCM and DSD signal since BIII requires different jumpers. According to TPA, SideCar should be designed for this purpose but after checking the details, it can only switching between 4xSPDIF and I2S.

The TTL input of Ian's SPDIF also can't work with the USB WaveIO. Since I don't have another SPDIF source and can't identify which part causes the problem.

Ian's FIFO can't read DSD stream, therefore DSD will go direct to BIII (if I can sort out the jumper problem) and switched by either SideCar or OTTO 2.

BIII + Legato will be powered by SSLV, FIFO + SPDIF + Clock will be powered by 2 x LiPO. I am still thinking how to power the WaveIO by LiPO since it need to drop 1.4V. May be use two diodes!

All you need to do, is place jumpers for DSD - and you can send both PCM and DSD to the pins with no worries. I've done something similar (eXD board, DSD pins to Otto, I2S pins to FIFO to Otto, Otto to Buffalo III with DSD jumpers set.

Works like a champ!

Just got the reply from Russ on jumper setting:

Stereo DSD and Stereo PCM?

There is no need to switch anything.

Even without sidecar You just need to:

connect D1 to D5
then D2 to D4 and D6
then D3, D7 and D8 to GND.

Now nice thing... the Sidecar module does this for you when PCM/DSD input is selected.

connect the SideCar to BIII and check the pin connection. It is different from what Russ mentioned. Only find the following connections are done by SideCar:
D1 to D5 (DSD1)
D2 to D6 (DSD2)
D7 and D8 to GND.
D3 and D4 are not connected to anything by SideCar.
