I´ve attached my library for the SHT21.

It has an internal statemachine inside the _iState, dont know if this was neccesary but i think the symbolic status of the device changes if it isnt "10" ?
It has a TON Timer of 50ms before Writing a measurement request ( i´ve only tested the No-Hold commands ).
The internal state machine has these states:
10: Write Temp measurement command -> Send to state 11.
11: Read/wait for respons, when respons is found -> Send to state 20.
20: Write Humidity measurement command -> Send to State 21.
21: Read/wait for respons, when respons if found -> Send to state 10.

Every read checks the statusbit of the second byte, to check if it is the correct measurement that is read(temp/humidity), and sets or resets the xTempValid and xHumidityValid booleans.
It dont use the checksum.

After a Temperature measurement request is sent, a 100ms TON is set, before doing a Read, same with Humidity Measurement, but only 40ms.
If the read isnt successfull it will try again in the next cycle.

I tried withouth these timers with 4ms cycle time. On the 17th Temperature read (68ms) I got a respons from the sensor, and the 7th Humidity read (28ms).
So to take some cycles of the Cpu and the bus, i think its the right way to go. But you could probably go down to ~65-70ms for a temperature read and ~30ms for a Humidity.

It also has a internal watchdog timer, which is needed if it doesnt get a respons at all (i made a short between the SCL/SDA lines and it got stuck in a reading state), when it runs out, it starts from _iState 0 (complete restart).

If you dont specify a I2C address, in _iState 0 it automatically sets the address 0x40 (decimal 64), which is specified in the SHT21 manual.




Its probably not the best written library but it works very well.
Hope it will be of some use to someone.

SHT21 Humidity & Temperature Sensor

Author: Oleg Wagner
Date: 3.09.2015
Version: 1.0.0.1

MAX7219 which enables to drive up to 20 casceded (daisy chained) MAX7219 devices
(7-segment displays as well as 64-LED matrices).

Following functions are included:
- Display Test
- Set number of digits
- Shutdown mode
- Set brightness/intensity
- Clear Digit or Row
- Clear all segments/LEDs of a device
- Write particular segments of digits
- Write BCD numbers
- Write characters
- Write multi-digit integer
- Write multi-digit floats
- Write particular LEDs in row
- init device
- all necessary methods to set up SPI communication and data transfer

A device description file is also part the library.

For first impression see attached screen shots.

I would like to share this library if there is interest (no engagement).

Update to 1.0.0.1 Version include:
Extension of device description file:

- Icon added
- Initialization parameters for devices:
- Intensity level
- Number of digits of the device
- Shutdown
- Display Test
- Clear Device

Extension of “Initialize”-method in library with setting of above mentioned parameters

because i had some problems with the standard Adafruit PWM and made my own version.
Sometimes i need the PWMs and / or the servo control function.

Use a Array[0..15] to send values from 0 - 100 for PWM function or 101 - 200 for servo control (1.01 to 2.00 ms Pulse)
I added a accessible trim function for servo pulse finetuning.
The State shows if the device is present and accessible.
The IN shows the actual frequency register value.
