Issue #709 | 状态: 已关闭 | 作者: sergerzet | 创建时间: 2020-12-16

There are no I2S_WS synchronization pulses. Checked the short circuits on the I2S bus-normal. soldered the pull-up resistor. Didn’t help. Looks like a software bug. What to do?

What hardware are you using? What firmware version are you using?

I have not heard of other people having issues with the I2S feature. It is more likely a hardware problem.

Esp32 devkitc v4 module, latest firmware version.

I put the chips of the 74HCT595 series, and they have a power supply of 4.5-5 volts. Apparently because of this problem.
