great job DQ828, could you provide more details on how to use SD card to store the file?
Sure happy to, the code is a work in progress, I have included it so you can see what libraries etc are needed.
Once you have downloaded the libraries #include <tinyFAT.h>
#include <UTFT_tinyFAT.h> I recommend that you should run one of the Demo's in the "example" folder in the UTFT_tinyFAT library.
You will need to get a standard SD card (not a mini or micro) format it to FAT16, How to Format a Fat16 SD Card | eHow.com.
Load the "pic.raw" files into the Root directory of the SD card, the "pic.raw" files are in the "Image-files" folder in the UTFT_tinyFAT library.
In the code you will need to change the "UTFTtf myGLCD(ITDB32S, 38, 39, 40, 41);" to
"UTFTtf myGLCD(ITDB32WD, 38, 39, 40, 41);
I think thats it!
If you want to display your own images, you will need to convert them to the ".RAW" format using Henning Karlsen converter & load them on the SD card. Dont put the files in a folder they need to stay in the Root directory.
You can see in my code how I got them to display, basically at startup the Lizard displays for a short time, the lizard aslo displays when I turn my system on, I m still working on the rest.
Oh, my courier font doesn't display properly
still working on that.With "myGLCD.loadBitmap(0, 48, 400, 144, "L_YGB.RAW");" the 0 & 48 = screen position, the 400 & 144 are the image size, as you can see I have been able to push the width of the image right up to 400 pixels.

Thanks DQ828
Just received the new BIII and is busy to carefully check everything and wiring before power it up. Will try the bitmap display with your suggestion later.
Received the new BIII yesterday and took an hour to solder all the connectors and jumpers. Then test it with the Bench PSU, 5.2V @ 460mA constantly, with all LEDs on Tridents and "Mute" on.
Use resistor to load the SSLV and confirmed it is working perfectly. Following the Legato setup procedures and adjust all the VRs. Then put the BIII onto the Legato and power ON.
The LEDs on the tridents slightly blinking, check the 5.25V power and it drops to 4.6XV, something shorted Switch off the power immediately, remove the BIII from Legato, power up and voltage back to normal 5.25.
Something on Legato overload the BIII. Check all the bipolars and FETs are fine. Seems the output buffer IC LME49600 has lower resistance to GND. I have no way to confirm whether it is dead. Have to order two new IC and replace them.

Yes Qusp, it took me most of the time to scraped off the soldermask at both sides of the sockets.
The buffer IC arrived yesterday and I replaced them last night, problem still exists, everything were fine before I put the BIII onto the Legato, but the 5.25V to BIII dropped to 4.6V when with the Legato.
Before I burnt the BIII, I re-installed the three SSLV with individual heatsink into the case with comment heatsink. I didn't realize any problem when measure the output of individual power supply.
Spent almost two hours, finally found two problems (actually they are the same). Both the -15V and the +5.25V have one insulation pad didn't perform their job. The GND of -15V and the POS of +5.25V shorted to the heat sinks. When putting the BIII onto the Legato and have the common GND, the +5.25V will become +20V with reference to the GND on Legato, this may be the reason for the burnt BIII.
I don't know whether the new BIII is still alive or not although ALL LEDs function properly. Still no sound from the Legato I haven't installed the jumpers for PCM input and will install them tonight.

Glad you found the problem finally. Hope everything is fine

Thanks Ian
Hope there will be music output from BIII after I add the jumpers. Will try to repair the burnt BIII again and your new i570 clock board with dual I2S output will be a perfect match for my Dual Mono config.

Also glad to hear you found the problem. It was really strange why an output stage would kill the chip, Hope the DAC survived the voltage stress.
Sure happy to, the code is a work in progress, I have included it so you can see what libraries etc are needed.
Once you have downloaded the libraries #include <tinyFAT.h>
#include <UTFT_tinyFAT.h> I recommend that you should run one of the Demo's in the "example" folder in the UTFT_tinyFAT library.
You will need to get a standard SD card (not a mini or micro) format it to FAT16, How to Format a Fat16 SD Card | eHow.com.
Load the "pic.raw" files into the Root directory of the SD card, the "pic.raw" files are in the "Image-files" folder in the UTFT_tinyFAT library.
In the code you will need to change the "UTFTtf myGLCD(ITDB32S, 38, 39, 40, 41);" to
"UTFTtf myGLCD(ITDB32WD, 38, 39, 40, 41);
I think thats it!
If you want to display your own images, you will need to convert them to the ".RAW" format using Henning Karlsen converter & load them on the SD card. Dont put the files in a folder they need to stay in the Root directory.
You can see in my code how I got them to display, basically at startup the Lizard displays for a short time, the lizard aslo displays when I turn my system on, I m still working on the rest.
Oh, my courier font doesn't display properly
With "myGLCD.loadBitmap(0, 48, 400, 144, "L_YGB.RAW");" the 0 & 48 = screen position, the 400 & 144 are the image size, as you can see I have been able to push the width of the image right up to 400 pixels.
I have no problem on converting the bitmap to RAW and loaded it into the SD, compiled without error but can't display the bitmap. don't know whether there is problem on converting the file. Can I have your RAW file for testing?

I soldered the three jumpers for PCM input. Connect the Arduino to BIII via I2C. The response to the volume control and display of parameters are much slower than normal. Frequency display also higher than actual. No sound output from Legato. Can anyone advise what should I do to find the problem?
1- Remove Legato. Connect direct to amp or preamp
2- Reinstall original firmware chip (this will give you full volume, but can reduce the volume in the computer if you are using USB output - or else use a preamp)
