esp camera i2s max clock?
Posted: Tue Mar 31, 2020 2:28 pm
Hello...
somewhere igrr mentioned that the max clock for the i2s module can be 20mhz.
I have a custom camera that has onboard 25mhz oscillator (so not xclocked by esp) and outputs a pixelrate of 25mhz.
I cant capture anything.
As to the i2s module, i understand that it is clocked by the pixelclock of the camera ? !
If 20mhz is max, i have to reduce the pixelclock.
maybe someone can confirm this upper limit of 20mhz.
