That's unfortunate, limited to 100ksps. It's an analog video signal so it doesn't need to be perfect, just not a complete miss. What about using the ULP's ADC instruction? https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/system/ulp_instruction_set.html#adc-do-measurement-w...

Hello. I'm trying to read an analog video signal at around 1.75msps and store that in PSRAM. I have the 16N8R ESP32-S3. A signal frame is about 1MB and processing the frame only takes about 22ms so I'm hoping I can read the ADC into PSRAM and every 1MB process the frame. I've read in a few posts tha...
