not sure if this is the right list to point out oddities in the documentation, but i'm reading this:
https://www.96boards.org/db410c-getting-started/HardwareDocs/HWUserManual.md...
and in the ToC, under "Low Speed Expansion Connector", there is no mention of I2S, but in the very next section, "Introduction", under
Actually, it says PCM/I2S, just like the specification.
"I/O Interfaces", one reads:
One 40-pin Low Speed (LS) expansion connector UART, SPI, I2S, I2C x2, GPIO x12, DC power ^^^should I2S be added to the ToC for consistency? or am i misreading something?
As per the spec, the LS connector must expose I2S/PCM. In other words, PCM data over I2S interface. In the pinout for the LS connector, the signals are named as PCM_FS, PCM_CLK, PCM_DO and PCM_DI on pins 16, 18, 20 and 22 respectively.
The text under the introduction could be fixed to say I2S/PCM to be consistent with other parts of the documentation including the specification.
Want to submit a patch to the documentation[1]? :-)
Regards, Amit
