H3 I2S Problem
I've found it's hard to configure H3's i2s engine to work right.
The datasheet give us such info:
and if we config the engine with the following register values:
| Addr | Value | Mean |
|---|---|---|
| 0x01C22030 | 0x00000001 | We want 2 slot/channel |
| 0x01C22034 | 0x00001031 | channel 0/1 is enabled |
| 0x01C22034 | 0x76543210 | sample 0 is right channel, and sample 1 is the left channel |
and we can download the test audio file from: Left/Right Audio Test 。
when we played the test file with the soc integrated audio codec, we can hear the left & right channel is splitted very clearly, but when we test the file with the i2s connected dac, we can find the left channel and right channel get merged together.
