As is usually the case, a few bugs crept into the v2 release. So, here is v2.01: TFT_HiFiDuino_v2.xx (14118 downloads ) (Note: As always, the code on this page may not be the current one, i.e. there may be a newer version available. The latest version is always up at the project’s official page.)
Also, here is a video of the code in action:
As I said, I will release a new revision of the Buffalo shield that will have better support for the B3SE.
Since that will probably take some time, in the meanwhile, this is what B3SE (or 32s or II) owners should do to their shields in order to support the B3SE:
The idea is to connect the photosensor side of one of the optoisolators directly to the IP_S header on the B3SE. In order to do that, you will have to cut one trace on the PCB and solder directly onto one of the optoisolator’s pins. That’s pretty much it.
On the new revision of the shield there will be a jumper where you have to cut the trace plus an extra pin so that you don’t have to solder onto the isolator’s pin.
Here is version 1.06 of the code:
TFT_HiFiDuino_v1.06b.zip (7200 downloads )
(11/12/2013: Update to v1.06b. Reason: minor bugfix) (Note: As always, the code on this page may not be the current one, i.e. there may be a newer version available. The latest version is always up at the project’s official page.)
The main difference is the support of Buffalo 3SE as well as an “always on” feature that bypasses the remote on/off sections of the code.
Here is the official change log:
– Compatible with Buffalo 3 and Buffalo 3 SE. Just comment out the relevant statement.
– Fixed “OS Filt” & “SR disp”.. They were not working correctly.
– Blue select boxes are gone.. they looked quite bad.
– Some other minor (mainly aesthetic) fixes..
A new revision of the shield is to follow (for improved B3SE compatibility).
It took quite a bit longer than I had expected but I am happy to report that Phase 1 of the TFT HiFiDuino project is complete.
The objectives of Phase 1 were the following:
– Have full control over the parameters of the ES9018 chip. Essentially be able to write to all of the useful registers.
– Be able to have full IR remote control functionality.
– Be compatible with both the MEGA as well as the Due Arduino boards.
– Be able to switch between all 8 of the supported s/pdif inputs, as well as between I2S sources (USB in my case).
– Develop an Arduino shield that would simplify the wiring of the thing as much as possible as well as provide galvanic isolation between the Arduino and the DAC board.
All of these objectives have been accomplished, so here is v.1.00 of the code: TFT HiFiDuino v.1.00 (6808 downloads ) (Update: there is a new version available! Click here for the latest version.)
If you happen to come across a bug, please let me know by posting a comment below.
Feel free to use it whichever way you see fit, modify it, redistribute it, whatever, as long as you do not profit from it.
Requirements:
– UTFT Library
– Fonts (included in the ZIP)
I will also make available the schematics & PCB for the shield, although it is not really necessary for operation of the controller.
Here is a preview:
Just a quick update:
– USB input added..
– Changes made so that the settings are stored into an 24LC256 EEPROM
