Hi. in what is "channel_mask" in this line?

alirezainallo commented 1 year ago

this is 0x3 (0b11) for even channel, for example: channel0_mask: 0x03 (0b00000011) channel1_mask: 0x0c (0b00001100) channel2_mask: 0x30 (0b00110000) channel3_mask: 0xc0 (0b11000000)

if you want use both just need to OR them (ex: (channel0_mask | channel1_mask) is for channel 0 and 1 together)
