TIMER_BASE_CLK error

[emid-alipour]

HI,
I have many error when I am compile example code:

my code is:
`
//This example shows how to animate graphics on a VGA screen. No backbuffering is used... just try it.
//You need to connect a VGA screen cable and an external DAC (simple R2R does the job) to the pins specified below.

it's about Audio timer, what's my problem?

Regards.

Hey, apparently TIMER_BASE_CLK has been removed since esp-idf 5.0 which you might be using, what fixed this problem for me was downgrading the esp32 boards library; I tried version 1.0.1 and it worked for me :)
