#65151 Netduino Libraries on GitHub

Posted by alesbedac on 29 May 2016 - 08:05 PM

You should write some description about what they do in github.

I Placed on github netduino libraries - which are available for download.

#65150 Netduino Automation - Digital I/O Shield

Posted by alesbedac on 29 May 2016 - 08:12 AM

Digital Iinput output shield for automation is completed,

* Working with 12-24V DC (integrated voltage regulator, optionally from 5-24V DC if you change the voltage regulator - what is very easy).
* 7 Digital outputs (500mA for all - what is enough for lot of relais)
* 13 Digital inputs
* I2C terminal 

product info : Info.pdf
manual : - Manual.pdf


#64972 Netduino Libraries on GitHub

Posted by alesbedac on 07 March 2016 - 07:13 PM

Hi All,


i am giving to all misc libraries. Currently are addes only two project, but tohers comming soon.

Lot of projects is based on project found on this forum. If you see this is close to your project send me message and i can add link to you original project

#63994 Boiler controller

Posted by alesbedac on 27 August 2015 - 06:48 AM

Hi All,


my current project is Boiler temperature controler.
PCB Shield description
* 7xDS18B20 (if i will use sensor indexing than i can connect much more sensors)
* 7x digial Outpout (12-24V DC)
* 6xdigital inputs (12-24VDC) or SPI LCD. If I2C lcd is used, than are these inpust available.

* and pinheader for i2c device (with 5 pins, 2 are data, one is GND aaand 5V and 3V3 

Curently i am using 4 sensors. and COM1 is conntected with bluetooth UART adapter to conenct with PC, what is now for upload parameters. These parameters are saved to I2C eeprom. I am using RTC DS1307 Shield with build in eeprom. On i2C bus i have next devices - 2x LM75 (temp sensor). One is for Indoor temperature and the second is for outdoor temperature. Picture show you 4 relais to switch valves.


Thats all for now :-).

#63129 Weather Station

Posted by alesbedac on 13 June 2015 - 05:24 PM



this is my weather station.

Data are saving on ThingSpeak server : 
* https://thingspeak.c...3996#publicview
* ToView current data is there very simple html web page with basic text formating

I was thinkign about windows klient for weather station. Than i got better idea to create client for all devices.
Currently i have two devices, the second is the temperature controler with Uart. So i wish to have an client which is able to connect with device via Seril or network interface.

This tool will be created for 
- configuring parameters (Serial/Network) device(s)

- Display current values on device (Serial/Network) 
- Display values on thingspeak (network device only) with filtering by last x values or by the date.

Newly atached screen show the current Device client tool status.
Actually working features
- connect device (serial/network)
- add device to device list
- Download parameters (serial/network), this property is displayed in other form which is not done.

#58038 TFT LCD (ILI9341)

Posted by alesbedac on 10 May 2014 - 07:56 PM

Probably mine, from And yes, a bit slow. I also collected info from various docs, good to see it can be used.



its your work...i hope its ok i have placed it here..please appologise me.

#57905 Need help with TFT display and SPI

#57826 Need help with TFT display and SPI

Posted by alesbedac on 29 April 2014 - 06:45 AM

I can place here me working example code if you wish...if you help me how to add file to new topic :-).

#57150 LM75 (I2C temperature sensor)

Posted by alesbedac on 26 March 2014 - 07:21 PM

Hi All,

problem solved, lot of thanks to GRISMO and MBROSSETT

Problem was with address pins ground and misssing resistors.


So how to work with LM75 ...short desciption :

1) connect SDA -> resistor 2K2 -> 3V(or 5V)

2) connect SCL -> resistor 2K2 -> 3V(or 5V)

3) Address pins must be always connected (to ground or VCC]

4) use program on TOP



Really nice working, again thanks to GRISMO and MBROSSETT.

#56216 Own IO Shield

Posted by alesbedac on 20 February 2014 - 06:31 AM

Hi All,


i didnt find any shield what will give mi 12-24V DC Inputs and outputs.

Thats why i have created my own IO Board.


Specifications : 

7x Digital Input (12-24V DC)

7x Diggital Output (12-24VDC, 100mA)

4x Analog


i2C (5x single row).


On this prototype is missing Fuse and Power connector, which comes with next board version.



I have received PCB, with profesional i have plan to do external IOs with using I2C interface
