Hello, we planned to put a ~110KB buffer into SPIRAM (SPIRAM chip size is 2MiB). Since it is the only thing we need in this memory area, we tried to use the simple method of integrating the SPI ram into the memory map, and access it with pointers. Note that the integrated SPI ram test is enabled and...

Added schematic snapshots of the reset and ADC circuit.

Did you try any of the default examples here? https://github.com/espressif/esp-idf/tr ... herals/adc Yes. First of all, it does not compile for S3, so I had to remove some parts that check the calibration type (function "check_efuse"). I also had to add a few lines that configure a different GPIO, ...

We are having issue getting the correct reading from our custom board with ESP32-S3-WROOM-1 module. In our design, we have connected ADC1_CHANNEL_6 (GPIO_NUM_7) in between two resistors, forming a voltage divider. The expected voltage range there is 1V5 to 2V7, which is of our battery power input. D...

Hi,
the issue is resolved by updating to latest IDF.

Debug output with loglevel=verbose: --- idf_monitor on /dev/ttyACM0 115200 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- I (24) boot: ESP-IDF v4.4-dev-3235-g3e370c4296 2nd stage Fi data ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x15 (USB_UART_CHIP_RESET),boot:0x8 (SP...

This is still an issue. To reproduce, all you need to do is copy the deep-sleep example, run "idf.py set-target esp32-s3" and "idf.py menuconfig" to configure/disable touch and GPIO wakeup depending on your board, and "idf.py flash monitor" it. Below is output from unmodified deep sleep example, usi...

Hi, I am using this code on ESP32-S3-DevKitC-1 https://pastebin.com/4WyxerTX Note Line 54 esp_sleep_config_gpio_isolate() removing this does not make a difference. I cannot get deep sleep to work. The device never enters deep sleep. Instead the WDT kicks after 5 seconds. If WDT for IDLE is disabled,...

You can use them as normal GPIOs (or peripheral pins routed over the GPIO matrix) by configuring them as such in ESP-IDF.

Please advise on how to do so, for ESP32.

Simply configuring them as output, disabling pull-resistors, and then setting a level does not work.

Thanks
