A C++ way to read a NTCThermistor for Raspberry Pico C/C++ SDK.
Download this library
mkdir lib/
cd lib/
git clone https://github.com/ShellAddicted/PicoNTCThermistoradjust your CMakeLists.txt accordingly:
# Add this line before target_link_libraries()
pico_add_subdirectory(lib/PicoNTCThermistor)
# Add PicoNTCThermistor to your target_link_libraries()
# Example: target_link_libraries(PicoTest pico_stdlib PicoNTCThermistor)
Example:
#include <iostream>
#include "pico_ntc_thermistor.h"
int main() {
stdio_init_all();
adc_init();
// Pin 27 = ADC1
// 10e3 = 10k ohm (Known resistor)
// 3950 = B value of the thermistor (Check your datasheet)
// 100e3 = 100k ohm (Thermistor R @ T0)
// 25°C = T0 (Usually 25, check your datasheet)
// 0 = num of samples (0 = Single read)
// Increase this to get more accurate results, if samples > 0 the samples will be averaged
