It also protects your Raspberry Pi from overvoltage or short-circuiting and simultaneously provides you with enough IO channels and channel configuration versatility. It features analog and digital inputs and outputs, RS-485, 1-Wire bus and a Real Time Clock. The Monarco Hat driver is v1.0.0.0 implemented as an FB device-driver. You can program your code in any language you desire, either visual or textual. 100% Open source, 100% Pure IEC 61131-3 code (ST) Changelog v1.0.0.0 Released FB based driver including demo project Retain data support via RTC (separate Buffered SRAM Package) <DeviceIdentification> <Type>501</Type> <Id>FFFF 0005</Id> <Version>1.0.0.0</Version> </DeviceIdentification> Hardware prerequisitories A Raspberry Pi, see https://www.raspberrypi.org/ A Monarco HAT, see https://www.monarco.io/ At least an 8 GB SD Card ... Hardware installation and setup Attach Monarco HAT to Raspberry Pi and power it up; sudo cat /proc/device-tree/hat/vendor should return "REX Controls". sudo cat /proc/device-tree/hat/product should return "Monarco HAT". Disable system console on UART sudo sed 's/ console=serial0,[0-9]\+//' -i /boot/cmdline.txt sudo reboot Install essential tools sudo apt update sudo apt install git Flash Monarco HAT EEPROM (to avoid manual installation of overlay) sudo git clone https://github.com/monarco/monarco-hat-firmware-bin cd monarco-hat-firmware-bin ./monarco-eeprom.sh update Software prerequisitories CODESYS V3 IDE available at https://store.codesys.com/codesys.html, CODESYS Raspberry Pi .package available at https://store.codesys.com/codesys-control-for-raspberry-pi-sl.html, CODESYS Raspberry Pi SL Demo or License (The Demo is unrestricted in technical capabilities but will only run for two hours straight, after which it stops and you have to set it in run again yourself by logging in) Contents of SVN directory : SVN Codesys Runtime installation Installing CODESYS runtime component on pi (Demo or licensed), just follow CODESYS online help steps, it's easy! https://help.codesys.com/webapp/_rbp_install_runtime;product=CODESYS_Control_for_Raspberry_Pi_SL;version=3.5.12.0 Or check this youtube video: [[embed url=https://youtu.be/6FPf3RHWyeU]] Package installation Monarco Hat v1.0.0.0 Package & Monarco Hat Realtime Clock SRAM Support Package Download Monarco Package v1.0.0.0 Download Support Package Monarco UART configuration Enable CODESYS to use the RS485 UART on the Monarco Hat. Switch to etc direcory and edit the CODESYSControl.cfg; cd etc/ sudo nano CODESYSControl.cfg Add the following lines; [SysCom] Linux.Devicefile=/dev/ttyAMA Now save and Quit nano. Now, do a forced NTP sync sudo timedatectl This will force to sync time with some time server and returns something like, depending on date/time and your time-zone; Local time: zo 2018-09-23 14:46:17 CEST Universal time: zo 2018-09-23 12:46:17 UTC RTC time: zo 2018-09-23 12:46:18 Time zone: Europe/Amsterdam (CEST, +0200) Network time on: yes NTP synchronized: yes RTC in local TZ: no Now you can use the HAT, RS-485 and the Real-Time Clock from within a CODESYS IEC application. Access the RS485 UART via a comlib of you own flavour in CODESYS (like CAA SerialCOM library). Running the CODESYS project Open the provided example project file. Check/Set SPI master parameters: Mode 0, SPI bits 8, Speed(Hz) 1000000 (=1MHz) => can be set up to 4 MHz, slower speeds avoid chance on crc errors Compile, download and run and enjoy! Limitations / Bugs All functionality of the HAT is implemented into the core of the driver. However I have no illusion that this driver will still contain bugs. Due to limited time resources, I am not able to solve every bug anymore, sorry... As this opensource software you are cordially invited to fix the bug and share your solution via a ticket. v2.0.0.x Experimental and under construction, NOT RECOMMENDED unless you like to tinker IO based driver devdescr.xml: vendor id set to 0004, device id set to 0005, see https://forge.codesys.com/drv/io-drivers/database/Home/ for details. <DeviceIdentification> <Type>501</Type> <Id>0004 0005</Id> <Version>2.0.0.2</Version> </DeviceIdentification> Ctrl Byte, HWConfig, UserLeds, UserLedMask Retain data support via RTC (separate Buffered SRAM Package) For the package and the source of v2, see the SVN repo under tags Acknowledgements v1 Realised in 2017. Special thanks goes out to Ingo Hornberger for helping out with difficulties and for his patience.
