Re: Support for FreeRTOS-MPU functions in ESP32-S3
@ESP_Sprite Do you know if there is currently a stable/non experimental/supported way on esp32-s3 to take advantage of the separation features? For example, say I want to run a complicated parser isolated, at the moment all I could find was the esp privilege Separation framework which has not been u...

Re: How to use miniz to create a compressed file that can be decompressd by gzip?
Not sure about compressing on esp32 and decompressing elsewhere but this works for me to compress on my linux host (and then i decompress on the esp32) python -c "import zlib; import sys; open(sys.argv[2], 'wb').write(zlib.compress(open(sys.argv[1], 'rb').read(), 9))" uncompress_file.bin compressed_...

ESP Privilege Separation on S3 and efuse hw read only question
I noticed ESP Privilege Separation project on github https://github.com/espressif/esp-privilege-separation which is very interesting. Unfortunately it is in beta and does not seem to support recent idf releases such as v5.1.1, it requires idf patches and looking at the example sdkconfig.defaults htt...

lowering the DC voltage on a circuit programmatically
I have an intercom that is based on a two wire system with DC 28 V It's an elvox duefili. With an esp32 + adc and a voltage divider I was able to sample the voltage. upon ringing the doorbell and opening the gate I can see the different voltage drop. I can also "see" my voice on a plot of the sample...

Re: ESP32 OTA via the BLE
For ble ota I'm not sure if there is any example is esp idf but you can find an ota mechanism that supports both serial and ble in https://github.com/blockstream/jade - it wraps the ota data in cbor messages It uses by default deflate compression via minix in the rom but you can skip that (it works ...

Re: Tagged version differences in git (release/v4.3 vs v4.3)
The former is the branch the latter is the tag.

M5 atom echo, using simultaneously the mic and the speaker, impossible?
The m5 atom echo comes with a PDM mic SPM1423 and speaker NS4168 i2s From https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/i2s.html Each controller can operate in half-duplex communication mode. Thus, the two controllers can be combined to establish full-duplex c...
