WebApr 20, 2024 · In CircuitPython ADC values are put into the range of 16-bit unsigned values. This means the possible values you’ll read from the ADC fall within the range of 0 to 65535 (or 2^16 - 1). When you twist the potentiometer knob to be near ground, or as far to the left as possible, you see a value close to zero. Web4 hours ago · In addition, CircuitPython has a built-in REPL (read-eval-print loop) that allows you to interactively test and debug your code, ... 3 x 12-bit ADC capable of 500Ksps, Analog to Digital Converter; 2 x UART (Universal Asynchronous Receiver/Transmitter) 2 x SPI (Serial Peripheral Interface)
WebDec 1, 2024 · ADC controls how accurately it can read a voltage. For example a 12-bit ADC can represent analog voltages with 12-bit values, i.e. 0 to 4095 (use the equation 2^12 - 1 to understand how the number of bits relates to the possible values). This means the 12-bit ADC can see 4096 different voltages (remember 0 is a unique value too). That’s WebThe following short Python programs will demonstrate essential operation of the Raspberry Pi Pico board.
