'i2s_chan_handle_t' does not name a type; did you mean 'intr_handle_t'?
Posted: Mon May 01, 2023 7:47 pm
Hi all.
compiling the example from: https://docs.espressif.com/projects/esp ... s/i2s.html
got error of: 'i2s_chan_handle_t' does not name a type; did you mean 'intr_handle_t'?
how to fix please?
Thanks
Adam
