SHT 1x sensirion

philippeb · November 21, 2021, 9:52am

I bought a temperature humidity sensor from dfrobot. I took this one because it has one enclosure and is better than a click board for outside use. The I realized that the SHT12 is not a real i2c device as it doesn’t have address. Is there a ‘easy’ way to handle this type of device with TinyClr other than creating data and scl signal by code

If this is not a standard protocol then you will have to implement on your own. This is usually not very difficult. Even an entire I2C bus in software is not that difficult to implement.

time ago “on tinyclr 1.0” was created (it include clk and data for four digit display) so i belive this can help you how to do it

using System.Threading;
using GHIElectronics.TinyCLR.Devices.Gpio;
// ReSharper disable UnusedMember.Global
// ReSharper disable MemberCanBePrivate.Global

namespace Bauland.Grove
{
    /// <summary>
    /// Wrapper class for FourDigitDisplay
    /// </summary>
    public class FourDigitDisplay
    {
        private const int AddrAuto = 0x40;
        private const int AddrFixed = 0x44;
        private const int AddrStart = 0xc0;

        private readonly GpioPin _pinClock;
        private readonly GpioPin _pinData;
        private bool _bPoint;
