Esp32S3 : Is it possible to configure a pin in output open drain with pullup and configure it as a peripheral pin?
Good morning, I am working with an Esp32S3 and I have pins that are configured as I2S peripheral pins. (Bit CLK pin). I would like to know if I can keep the same configuration for this pin (I2S Bit clk) and configure it as output open drain with pullup at the same time ? (via gpio_config method). Ca...

Esp32S3 : Library for HighPass numeric filtering ?
Good afternoon, I would like to know if you have any library that can be used to realize a high pass numeric filter on a signal sampled at 16KHz. I am sampling a signal at 16KHz and I would like to remote the 50Hz present in this signal because of electromagnetic disturbances. Moreover, if you have ...

Esp32S3 : Is there a timer in the RTC domain ?
Good afternoon, I am working with an Esp32S3 and I am looking for a timer that I can read from a program running under the ULP RiscV processor. The goal would be to have a timer running that I can read in order to determine the amount of time elapsed between to part of the ULP RISCV program. Do you ...

Esp32S3 : Use of General Purpose Timer
Good afternoon, I am using an Esp32S3 Wroom 1U device in order to create a program. In my application, I want to create a timer using the General Purpose Timer API. Using the following lines : uint64_t RawCount = 0; gptimer_handle_t gptimer = NULL; gptimer_config_t timer_config = { .clk_src = GPTIME...

ESP32S3 : Is it possible to change the Flash Encryption configuration ?
Good afternoon, I am using an Esp32-S3-DevKit-C-1 kit in order to test the flash encryption methods. So, I have configured a project using flash encryption set in Development mode with a random key generated by the chip itself. The project has been compiled and downloaded in the DevKit-C-1. Everythi...

Re: ESP-IDF : How to configure the ADC in continuous mode for 2 channels please ?
Moreover, in this configuration, how are organized the samples/bytes in the output buffer when
we are calling the adc_continuous_read method.
Because we have 2 channels, are the bytes interlaced in the output buffer ??
Best regards,

ESP-IDF : How to configure the ADC in continuous mode for 2 channels please ?
Good afternoon, I am working with an Esp32S3 and at the moment, I am using the ADC1 module in continuous mode in order to read samples on one channel only (Channel 7). The configuration is the following : esp_err_t AdMeasureInit; adc_continuous_handle_t AdcHandle; adc_channel_t channel[1] = {ADC_CHA...

Esp32S3 : VFS Component. How to determine Freemem and Used mem on a FileSystem ?
Good afternoon, I am working on a firmware running on an Esp32S3. I have 3 partitions that are "referenced" using Virtual FileSystem component and a FileSystem is mounted on each partition. Using VFS, is there a way to determine the amount of free memory (In bytes) and the amount of used memory (In ...

Esp32S3 : Is it possible to access the OTA partition where the firmware is running in order to change some bytes ?
Good afternoon, I would like to change some bytes of the OTA partition where my firmware is running in order to create a CRC problem. The goal would be to detect this CRC problem using the function esp_partition_get_sha256. Unfortunately, when I try to write some bytes of the current OTA partition u...
