Re: Ceramic Chip Antenna Design with the ESP32-S3FN8

I've created a layout for the antenna for the ESP32-S3FN8 based on: https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32s3/schematic-checklist.html#rf-tuning https://www.lcsc.com/datasheet/lcsc_datasheet_1810201611_Walsin-Tech-Corp-RFANT3216120A5T_C127629.pdf https://do...

Re: Ceramic Chip Antenna Design with the ESP32-S3FN8

I found where default values are recommended. I did not realize I had the generic page open and thus did not see the specific recommendations for the S3 line. https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32s3/schematic-checklist.html#rf-tuning is a link to the plac...

Re: Ceramic Chip Antenna Design with the ESP32-S3FN8

You can add a CLC (capacitor-inductor-capacitor) filter. It can help mitigate noise and improve signal quality. The big question I have there is, with what values? It is my understanding that these can only be acquired via tuning for each board so I wonder if having them without tuning would do mor...

Ceramic Chip Antenna Design with the ESP32-S3FN8

I am a hobbyist. I have made an application specific board with the WROOM-1 N16 variant, but decided that while making a revision to add features, I would switch to the ESP32-S3FN8 to save cost on board manufacture, and to get used to the process of setting up antennas as not all MCUs are as conveni...

EspExceptionDecoder Not Working in PlatformIO 6.1.11(latest release) with ESP-IDF 5.1.2 (stable)

I am trying to troubleshoot getting the esp32_exception_decoder to work, but it's not decoding exceptions as expected. The baud rate also gets knocked down to 9600 (maybe due to changes the debug modes I've enabled bring), but that is beside the point. To Isolate the issue, I've created a fresh proj...

Re: API to get CPU frequency

In 5.0+ it seems that esp_clk has been rendered something which is not stable/not something that should be relied upon. Is there any other way to get the clock speed now that this is no longer a recommended possibility (requires using esp_private api elements)? I was hoping to use this to do bit ban...
