They seem to work: 8 channels (4 stereos) are accessible through a I got a power supply with the DIYINHK board and soldered both in my amateurish way and The D8’s USB input connects directly to an XMOS based daughter board and removing the board revealed labels next to the pins! I thought there was good reason to believe the connection would be straightforward: I’m attempting to hook an Alientek D8 digital amplifier to this board via i2s and Next up: connecting it to my PCM4222 EVM ADC board.Ĭan I have your help in a matter of connecting a DIYINHK multichannel board? The left header is the XSYS connector for uploading firmware to the XMOS. The OLED screen is connected to one of the side headers, like this: The same multichannel restrictions I mentioned above apply to the I2S inputs. The rest of the input channels should be pins DIO2, DIO3 and DIO4. For 2 channel operation you will need to connect the DIO1, BCK & LRCK pins. The pins in yellow are the I2S DATA inputs.

I should repeat that multichannel operation with the provided driver is only possible at the moment with Windows 7 (and possibly Linux & Mac OS). I say “should” because I haven’t tested them. The rest of the output channels should be available at pins DO2, DO3 and DO4. For 2 channel operation you will need to connect the DATA, BCK & LRCK pins. It is a good idea to use all of the pins for making the connections, since ~800mA is nothing to sneeze at. I have marked in red the power supply input. Now, if these pinouts look somewhat cryptic to you, you are not alone. These are the pinouts, according to DIYINHK: The board has a ton of exposed I/O, split into three 0.1″ headers. They sent me a link for an even newer driver, v3.20.

If you want multichannel you’ll have to go back to Windows 7 (v1.67) (or perhaps Linux or Mac OS, it isn’t clear.).ĭIYINHK’s site says that the latest available driver is v2.26, but I did not find such a driver in their downloads section, so I emailed them about it.
#XCORE USB AUDIO DRIVER MAC OS#
Linux & Mac OS don’t need a driver.Īn interesting detail is that the Windows 10 driver that is available only supports stereo operation and no multichannel (v2.26).

It comes with a fully featured Thesycon driver for Windows. Beware, a weak power supply or an inadequate connector will cause to board to not power up. It needs a relatively beefy 3.3V power supply, capable of providing a maximum of 800mA (even though a typical power consumption is in the neighborhood of 570mA). There is provision for powering two of the oscillators externally, by removing a ferrite bead and applying power through one of the headers. The board (a 4-layer design, btw) comes with three high quality NDK NZ2520SD Ultra low phase noise oscillators. The board I bought came with the default firmware, which supports:Ī maximum 32 channels can be supported with the right firmware (not provided by DIYINHK).
#XCORE USB AUDIO DRIVER PLUS#
Plus use a cool OLED display as a VU meter. Plus I2S inputs, besides the usual outputs. Tons of channels of high-resolution audio. So, what can we do with all this horsepower you say? It’s simple. The specific chip used by DIYINHK is the middle-of-the-line XU216-512 which corresponds to some pretty serious horsepower: 16 logical cores for a total of 2000 MIPS, 512KB SRAM, 2MB FLASH. About a month ago DIYINHK released a USB to I2S interface board based on the brand new and all-powerful XMOS xCORE-200 chip.
