This commit multiple issues with the following RMT TX tests:
- rmt_multi_channels_trans_no_dma
- rmt_multi_channels_trans_with_dma
The following issues are fixed:
- Channel stop times are now tested using TEST_ASSERT_INT64_WITHIN(). The
previous method did not account for the case where channel 1 finished before
channel 0
- Increased synchronous stop time delta for esp32-c6
- Increased main task stack size to prevent stack overflow onesp32-s3
The legacy driver can't handle the breaking change between esp chips
very well.
And it's not elegant to extend new feature like DMA, ETM.
The new driver can return a opaque handle for each RMT channel.
An obvious transaction concept was also introduced.
TX and RX functionalities are splited out.
