ESP-IDF component (RMT) debugging
Hi, right now I'm debugging an application implementing an RMT led strip. Unfortunately I cannot debug rmt_tx.c a.t.l as obviously there are no debug symbols for this standard components. I can set a breakpoint, that works, but of course no watch expressions and no local variables e.a. I suspect thi...

API to get CPU frequency
Hi,
did a search but keep getting HTTP ERROR 500, so I ask here.
It there an ESP-IDF API function to get the current CPU frequency?
Thanks

Re: ESP32-S3 GPIO3 does not select external JTAG when low
Hi there, thx. I am experienced in programming but new to ESP32 (came from STM32), so please bear with me :) I did find DIS_USB_JTAG and DIS_PAD_JTAG, but not STRAP_JTAG_SEL. This is my efuse summary: ``` C:\Users\offic>espefuse.py -p COM4 summary Connecting.... Detecting chip type... ESP32-S3 espef...

Re: How to detect a cause of interrupt on GPIO (rise or fall) ?
I use method 1.
There is no need to read the GPIO via ADC. Simply use gpio_get_level(gpio_num_t gpio_num).
HTH

ESP32-S3 GPIO3 does not select external JTAG when low
Hi team,
this is my first post here.
I want to use ESP32-S3 with an external JTAG (ESPPROG). So I strapped GPIO3 to GND as documented.
Nevertheless, the external JTAG does not work. The connections are correct, and my ESPPROG worked ok with ESP32.
Any ideas appreciated.
