Interface board for Flowcode V8 and above. Now added RTC
The interface board enables Flowcode simulator to work really well with actual hardware.
It is possible to test hardware is working as expected, without programming any target devices, each time a change is made.
You don’t send the flowchart to the interface board either!
You can observe all the commands sent two and from Flowcode & hardware on the console.
The interface board is available from here
The interface board is compatible with all embedded targets!
I will be using two lots of hardware to demonstrate with the USB version of interface board.
LCD with I2C backpack & Wii nunchucks.
If you have a LCD I2C backpack then just connect the LCD backpack to 5v supply and I2C SDA/SCL connections of the interface board.
Make sure switch on the interface board is selected for 5V & the jumper is going across LED 2 pin header.
I used DuPont female to female connections as I have got an interface board with all the male headers soldered on to it.
Plug the USB into the interface board and PC then load Run Flowcode.
Load the attached I2C Backpack LCD.fcfx
Within Flowcode select View Console and select Interface Board.
You can just run the simulation or single step by pressing F8.
The console will display com port that is connected to the interface board.
The brightness of the status LED will be dim except when commands are being sent or received, then will flash much brighter.
The hardware should match the simulation: As there is no hardware to program you can modify the flowchart then run the simulator again.
You will see all the changes on the hardware LCD.
Unplug USB.
Nunchucks:
IMPORTANT: MAKE SURE THE VOLTAGE IS SET AT 3V3
Connect nunchucks to the power and I2C of the interface board.
Plug in the USB then Run Flowcode & load the Nunchuk_InterfaceBoard With LCD.fcfx flowchart.
After selecting Run, I’m now moving the nunchucks is different directions, holding down button C and pushed the joystick to the left.
As I moved the hardware, the Flowcode simulator match perfectly: Now I know without sending code to any targets, that my hardware will work.
If for some reason the hardware does not work with simulator then check the device manager for the USB serial device and what port its connected to: Next select properties of Serial board on the 2D panel & change AutoDetectPort from Yes to no.
Make sure correct com port is shown.
The com port is also shown on console at the very top interface board data.
If you are interested in how Ben created the interface board (both hardware and firmware) then check this out, Very interesting!
On that page you will also find examples for GLCD's and MPU950 accelerator, gyroscope, and digital compass (magnetometer).
Along with firmware source code
Drivers for the board can be found here
Driver was not required for my interface board to work.
Many thanks to Ben for creating & getting all the hardware and Flowcode to work together, he has done an amazing job.

Re: Interface board for Flowcode V8 and above
Hi Martin
Thats a good news thanks a lot.
I have placed an order.
one more little question.
Do you know the difference between:
Embedded Interface Board I2C SPI PWM ADC DAC Servo (WIFI Slave)
Embedded Interface Board I2C SPI UART PWM ADC DAC Servo (USB Slave)
regards
Stefan

Re: Interface board for Flowcode V8 and above
Hi Stefan,
The USB slave connects to the controller PC using USB.
The WIFI slave connects to the controller using WIFI (ESP8266) allowing say the embedded functionality to be controlled from a networked device, mobile device or the internet. The WIFI module connects via the UART and hence that is no longer available.
Both firmware versions are available on the github link and can easily be swapped using a PICkit.
Many thanks to Martin for such a glowing product review

Re: Interface board for Flowcode V8 and above
Hi Stefan,
Your welcome.
I'm finding the board so handy.
No more recompiling after further flowchart changes is brilliant!
Thanks Ben,
I was so impressed with its functionality,
I thought writing a bit about it was the least I could do!
It's my go to board for all my future projects, before I even choose a target device.

Thanks and You're welcome Martin.
I found it interesting.
Going to try multiple items connected.
E.g 2 or 3 x I2C + 1 x SPI.
Need to order more gLCD's

Re: Interface board for Flowcode V8 and above
Attached is a version for the DS1307, DS3231 & DS3232 Real Time Clock.
As soon as Flowchart is loaded, If not updated Flowcode (Help, check for Updates...) on or after 02/Oct/20 then you will need to run the update.
Only hardware required is the RTC and interface board (Set at 3V3).
When you run Flowcode simulation, it will read the RTC hardware to obtain the date and time.
If either the time or date is out, you have just received a new RTC module or you just replaced the battery, in which the time will default to: All you do is select switch A0 until seconds stop incrementing.
As soon as you release the switch, the RTC module is automatically updated to the PC time and date: You will end up with the correct time and date on your RTC module: How good is that?
This will be a godsend if you have multiple RTC modules that require setting.
Note the Flowchart should also work with any target device without the interface board..
The switches are used to manually set time and date.
However that's the long way around of setting RTC!

Hi Abhi,
I have just checked for the ebay listing.
Postage is £2.20 for India, which is just under 209 Indian Rupee.
On the listing you will see Posts to:Worldwide See exclusions.
Select the See exclusions link and select India.
Hope this helps?

Re: Interface board for Flowcode V8 and above. Now added RTC
Hi Martin,
The instructions for setting up the WIFI are now listed on the readme page here. I've added the password too as that info was missing.
https://github.com/RowlandTechnology/Interface-Board
The default WIFI network should be "password" all lowercase.
Let us know how you get on.

Re: Interface board for Flowcode V8 and above. Now added RTC
Hi,
Arrived today and looking good..
The password for the default wi-fi is 'password' - and there is an error in the instructions - 192.16.4.1 should read 192.168.4.1
Not sure where to go next - how do I get FC to talk to it via wi-fi??

Re: Interface board for Flowcode V8 and above. Now added RTC
To talk to it via wifi you need to configure the Interface Board component properties like this.
Component is under API -> SCADA Slaves -> Interface Board
Change the network interface property until you get sensible values for the local IP of your machine.
Change the Board IP to match the module IP, you can do an auto scan to find the IP (takes a while) or you can refer to your WIFI router config page for the connected device list.
To control the interface board you can call the component macros directly or you can do what Medelec is doing and use SCADA Slave Injectors to catch I2C, SPI or UART data and forward to the interface board behind the scenes.
The Log mode property is best in Command Mode to allow you to see the comms in real time on the console window when running the sim.
Here's a quick example using a I2C enabled component.

Re: Interface board for Flowcode V8 and above. Now added RTC
Hi Ben,
Thanks - I'll have to play some more...
I got a ssd1306 oled display running on i2c (albeit slow - works - hoorah)
Haven't managed to get wifi going - boards don't show up as connected on router, not do they output their network (I entered details on the page!)
The auto-connect doesn't find them either.
The usb board - I noticed an oddity. The list of USB ports includes only the ports available when the sketch was loaded into flowcode. So if the board is plugged in then you can't select it (auto does work ) Reloading the sketch makes the port available in the list.
The pins for BT connection - what order are they? I'm tempted to solder a header block so I can plug in a hc-05 if needed?
Martin

Hi Martin,
glad you have got ssd1306 oled display running.
If you want to give the Wifi a try I can take you through setting it up step by step.
I have got my interface board working via Wifi, with help from Ben.

Re: Interface board for Flowcode V8 and above. Now added RTC
Yes, please, a walk-thru would be great.
Particularly what we need to add to code to make it work with the board. Slightly on the back-burner while I played with fingerprints - but I 'd try adding it to the dfplayer code in the first instance?.
(Ben kindly 'released' the code for the i2c oled display a while ago - which surely includes support - so I'll study that some more (plans for that too - time pressure is bad at the moment!))

Re: Interface board for Flowcode V8 and above. Now added RTC
Power up interface board.
Scan for new Wifi connections, you should see one named InterfaceBoard.
Connect to it using password as the password.
When connected, on a browser enter address 192.168.4.1
You should get a prompt for SSID and your SSID password.
When entered details and Register, it will state ‘SSID and Password collected.
Connecting to SSID.’
If successful, then the wifi for InterfaceBoard should disappear, kicking you out of the connection.
You should only proceed to the next stage if you if cannot see the InterfaceBoard in available WiFi connections.
Check waht your IP address is by using powershell or command prompt and enter ipconfig.
With flowchart loaded, select the interface board properties from the panel.
Under Connection Properties for NetworkComms1::NetworkInterface you will need to select a number from the drop-down so that NetworkComms1::IPAddress shows as a valid IP address e.g. 192.168.0.43 i.e the value you get with ipconfig.
Mine works with number 5.
When that is done you can select the console and run the simulation.
If the Interface board tab is selected, the very first time of running you should see something like this: Should all be set up once you see 1 Devices Found.

Re: Interface board for Flowcode V8 and above. Now added RTC
Thanks - yes that works!
I'd missed the Network Interface step (although I'd tried a couple of different values - just not the right one )
So after a long search - board found at 245!
Brilliant!

Re: Interface board for Flowcode V8 and above. Now added RTC
Hmm - sort of works..
Testing with i2c oled (which worked aok on usb) - the board sort of worked.
With a lot of LED flashing - the display cleared (mostly) and printed Hello World (also mostly)
But lots of corruption / missing pixels etc. Maybe a speed issue?

Thanks Martin, that's really interesting.
I'll investigate this and see if there is a way to improve the WIFI communications to make it a bit more solid like the USB.

Hi Jorgen,
Yore're welcome.
I love my interface board.
Especially with DS1307/DS32xx.
Makes setting time and date so easy.
I'm sure you also come to the same conclusion.
I don't get any commission on the board, just find it so useful.
Hence the reason for posting about it.
