Re: External battery charging when connected to USB-C power
You need to be a bit more specific. What hardware are you using exactly, how have you connected it, what battery do you have connected? Just 2 normal rechargeable battery in a battery holder connected to 3v3 and ground PINs ... You're not really helping. What's a 'normal' rechargable battery in thi...

Re: USB-C to USB-C not working, USB-C to USB-A working, have pulldowns
Don't worry too much about it. You're only working with USB1.1, which will still work OK if you route it over two parallel pieces of wet string; your layout will work perfectly fine.

Re: ESP32-S3-PICO-1 Issues
Do you have access to the U0TxD pin? If so, do you see serial chatter on that when you apply power to the board? Also, can you post the schematics?

Re: opencv component overload DRAM.bss , how can i put into PSRAM
If you enable that, you can mark variables to live in PSRAM BSS rather than internal BSS. Example:
would become
to allocate it in PSRAM.
Code: Select all
char very_big_variable[1024*1024];
Code: Select all
#include <esp_attr.h>
...
EXT_RAM_BSS_ATTR char very_big_variable[1024*1024];

Re: how to configure the ESP32S3 as USB mass storage
There's an example included in ESP-IDF for that.

Re: problem with the esp32 led
You mean the red LED that is on the board? That is not controllable; it's always on when the board is powered.

Re: Can ESP32-C6 use GPIO to wake up Deep Sleep?
I noticed that External Wakeup can be used to wake DeepSleep with RTC GPIO, but I didn't find any description on the web about which pin of the ESP32 C6 can be multiplexed as RTC GPIO. Can you make a suggestion? See the datasheet , section 2.3.2. Long story short: GPIO0 to GPIO7 are RTC (LP) GPIOs.

Re: opencv component overload DRAM.bss , how can i put into PSRAM
There's an option for that somewhere in menuconfig. Note that you do need to annotate the bss variables you want in psram with a certain attribute; see the help for the menuconfig option.
