I know the problem is with my understanding of "continuous conversion mode" so I really hope someone will have the time to help me understand it. Why does the result register saturate? What do I need to do in the code, or in the configuration, to get valid results using continuous ...
I've set up the ADC in continuous (DMA) mode to store samples to a 1024 byte buffer with 256 byte frame size. The sample rate is 40 kHz and the resolution is 12 bits. I'm feeding a 2.2v, 1 kHz sine wave to the input (input looks good on the scope). I've set up the code...
I'm new to ESP development and currently working on a project where I need to read values from the ADC and send them via UART. I've encountered an issue with ADC conversion, and although I've tried to adapt examples from esp-idf, I'm unsure where the error might be in my code....

As an example, a tri-band circular-to-circular (CTC) polarization conversion metamateiral (PCM) was designed by a nonlinearly dispersive phase difference. Using such PCM unit cell, a tri-band quasi-continuous phase gradient metamaterial (PGM) was then realized by virtue of the Pancharatnam-Berry...
In accordance with known concepts of interactive computer graphics, the invention makes use of a windowing system to provide a conversion from the world coordinate system of the user to appropriate geometric coordinates suitable for the physical display device of the workstation, i.e. the cathode ...
UV-vis spectroscopy was used to assess the conversion of KMnO4 at different durations, as seen in Figure S3. The main peak of MnO4− disappears after 5 min and the color of the solution changes to green through the first step of the reduction, whereas in the second step, the color ...
(Supplementary Fig.12a, b). At the critical temperature of around 83 °C, adequate photothermal conversion could drive the continuous rotation of the Möbius actuator at a speed of 4.9° s−1(Supplementary Fig.11d). Below 70 °C, the short time scale of light irradiation on the ...
In this work, for a semicontinuous emulsion polymerization reaction, it is shown that using a redox initiation system at 40°C, substantial modifications in copolymer chain composition with conversion can be easily obtained. To test controllable trajecto
