  Hi guys,

  I'm very sorry if the following is a stupid question.

  The Spresense documentation says:

  The sampling frequency is set to 64Hz for LPADC and 16KHz for HPADC. (§ 1.15.1)

  My problem is that I need to use a much higher sampling frequency when using the analog pins. Is it possible to increase the sampling frequency of the HPADC pins?

  The CXD5602 user manual says on page 957:

  Table ADC-771 Sampling Rate Range Supported by the HPADC Clock Source Clock Frequency (Input to SCU) Supported Sampling Rate Range Over Sampling Frequency RCOSC 8.192 MHz 16 kHz to 32 kHz 2.048 MHz 1 Hz to 32.768 kHz 1 Hz to 32.768 kHz None (actual rate conversion) RTC 1 Hz to 32.768 kHz 1 Hz to 32.768 kHz None (actual rate conversion) XOSC 13 MHz 16.927 kHz to 33.854 kHz 2.167 MHz

  So for my understanding it would be possible to increase the sampling rate to 2.048 MHz or 2.167 MHz without down sampling. Is that correct?

  Another question is if it is possible to do it with the Arduino IDE? Could I use register manipulation or something like that? I know for example that it is faster with an Arduino UNO to use something like ADCSRA register instead of the read functions that have got some overhead. Are the registers accessible with the Arduino IDE?

  Thanks in advance for your help!

  Best,

  I'm doing tests with a Sony A7 III ILCE-7M3 device, the remote SDK driver (With USB cable). under windows or Raspberry PI4 (Ubuntu64) always the same result of the RemoteCli software does not detect the device. Any idea?
