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.
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.
A library for UPS PIco for Raspberry Pi. Includes the following functions:
- read voltage
- read temperature
- read analog inputs
- read other parameters
- control LEDs
- control of cooler (including automatic control based on temperature)
- Still Alive Timer (watchdog which will reboot the Raspberry Pi if your code will stop)
- initial configuration of the device out of your code
Here is a library I made for the device LSM9DS1, an Accelerometer/Gyro/Magnetometer form ST life.augmented, on a break-out board from Adafruit. (I had to zip the library-file since the size was more than 500kB, which is maximum upload file-size for this forum.)
The device has actually two slaves, but I chose to integrate them both with on device-description. It doesn't matter if the user assigns a slave address in the project, the code in the library alters anyway between two different slave-addresses when writing/reading data.
Though the device has built-in FIFO-registers, for faster and less time-/power-consuming readouts, I have not used this option in this version of the library. Instead, the readout is timer-controlled, with a user-specified read-rate.
Here is my Library for some I2C devices for CODESYS.

Although include the BME280 Environment sensor and an SD1306 Display Driver.
Look at google for these little funny Displays.
All fonts are working on the display, but not the biggest. There the bits have to be twisted.
If you find any problems, tell me, the Drives have not been tested all.
Don't look at the documentation, there is none ... .
In the I2C_Base FB I did write some info’s for the muxing.
With the muxing IC you can connect about 33554432 BME280 on the raspi, but then bus cycle time is no longer a problem .
You will need the OSCAT building lib to compile. i can not uplode it here like the OSCAT BASIC lib(to big), so try the lib from the store.

There is a simple example how to generate a QR-code and show it in web-visu: Example_QrCode_RPI.projectarchive
Image Image
Requirements:
You need to install qrencode:
sudo apt-get install qrencode
You need to install OwenStringUtils library. It included in projectarchive or you can install it separately: download
It's nice lib with additional string functions like ASCII/Unicode conversion, formatting and parsing.
In example used SysProcess library.
So you need to add in /etc/CODESYSControl_User.cfg next lines:
[SysProcess]
Command=AllowAll
Keep in mind that you need to have write access rights:
sudo chmod 0666 /etc/CODESYSControl_User.cfg
You need to set write access rights for /visu directory:
sudo chmod 0666 /var/opt/codesys/PlcLogic/visu
You can see qr-code in web-visu, but not in service-visu (CODESYS IDE-visu).

Hello,
Here is my Library for some I2C devices for CODESYS.
You can place all devices behind a multiplexer to reduce address conflicts.
Although include the BME280 Environment sensor and an SD1306 Display Driver.
Look at google for these little funny Displays.
All fonts are working on the display, but not the biggest. There the bits have to be twisted.
If you find any problems, tell me, the Drives have not been tested all.
Don't look at the documentation, there is none ... .
In the I2C_Base FB I did write some info’s for the muxing.
With the muxing IC you can connect about 33554432 BME280 on the raspi, but then bus cycle time is no longer a problem .
You will need the OSCAT building lib to compile. i can not uplode it here like the OSCAT BASIC lib(to big), so try the lib from the store.
