I often find the error lies between the chair and the keyboard.
There is no configuration file. The __IMXRT1062__ is passed to the compilier when the code gets built using the -D option Paul mentioned. See here......
No worries. I pushed some commits for this and to add slave support for i2s oct input.
The control objects just set codec configuration via i2c or maybe spi. The input_xxx and output_xxx stuff has the actual i2s configuration.
In input_i2s.cpp ...
CORE_PIN13_CONFIG =...
I've got it working for teensy 3.6 I was looking at the slave stuff in output_i2s2.cpp instead of output_i2s.cpp. The frame-sync-early and inverted-frame-sync bits in the SAI registers give the...
I would be very interested in the details. How did you get usb audio on the T4? I didn't think that was implemented.
I've got the data out of the teensy on my scope and I can see that disabling frame sync early is not working. The samples are starting a bit after the FS transistion. Looking at the data from the...
Read on... page 12 describes a PLL mode that generates it based on LRclk and BCLK.
Yep you are correct. I put them on a scope and the FS is at 44.1k, BCLK at 64 * 44.1 and the MCLK is 384 * 44.1
When I tested with my PCM5102 I didn't need the MCLK
When I connected the roland device to the PCM5102 dac I set it to Left Justified mode.
There is a timing diagram for that on page 14. It would appear that the LRClck is also inverted in that...
I don't have much documentation. I have a service manual that has a schematic for the device Roland made to connect to the header I'm using. The header and schematic is on pg 59.
I've figured...
Hi,
I have a Roland MV8800 sampler. It has an expansion header that provides four "i2s" output streams (8 channels) and an input stream (2 channels). Additionally it has a ttl level midi in and...
Great, thanks Paul
I want to build a box that provides midi routing and a usb midi interface
- connects to a PC by USB and provides 16x16 USB midi to the PC.
- provides 12 x 12 midi serial ports
- has a display...
