What I do is take a screenshot of the area I want, using a free program called Greenshot. When you take a screenshot, after selecting the area you wish to capture, a popup appears asking how you want the screenshot saved. Save capture.png I save to paint. I then use paint to save as png. You could o...

Hi Bob, that's excellent. Thanks for letting up know. could i ask how you inserted the png pic please Select the Attachments tab, then Add files button to add the image. You can place the image anywhere within the post by selecting where you want the image to go. Select Place inline for the image yo...

Whoops, sorry.
The divider is to the power of
No divide is 10 to the power of 0 = 1.
I used 10 to the power 1 = 10
To fix that just change the 1 to 0:

Hi Bob.
You're welcome and thank you for the nice comments.
The flowchart is a demonstration of how I would divide down depending on the result.
I have not checked the rest of the flowchart, nor have I tested o hardware.
If you find it does not work as expected, then I will help you further.

Hi Bob.
I have attached the way I would handle the dividing.
With the attached flowchart,
If R = 123.456 then the result on the display should be 123.4Ω
If R = 123456.789 then the result on the display should be 123.4KΩ
If R is 123456789.01 then the result on the display should be 123.4MΩ

Hi Bruno. The update has been pushed to the system, so hopefully all is back to normal. I have a BMP280 and a BME280 Although for the BME280, I added a flowchart example here that shows how to calculate the altitude ft & m from the pressure reading if you are interested? It can easily be changed to ...

Hi Bruno.
Sorry that was my fault.
The correct version will be available as the latest version, as soon as possible.

Hi. As you are using V9, can you please register for V9 forums from this site I'm sorry there is nothing you are able to do to generate the C or hex file, without the required component packs in place. There are free components that are listed here Have you started the 30day free trial yet? If not, ...

Hi Miguel.
You're welcome.
I'm happy I have helped you.

Hi, as servos have all their electronics built-in, you don't require a L298 controller, which is for DC motors. Unless you are creating your own servo with DC motors? In that case, you will need some form for positional feedback from the motor. If it is a servo motor you are using then the signal pu...

Hi Rod. I have tried your flowchart with EPIO40P which also uses 33EP256MU806 and it's working as expected. With analogue i/p connected to the + supply, my logic Analyser showed: UART 33EP256MU806.png What connection have you got the analogue voltage connected to on your BL0032 & can you measure the...

Hi Rod, For your flowchart to do what you want, It looks like the modulus is the way to go since you have not got any other modulus functions in your flowchart, except for the timer interrupt. If you did have modulus functions in other user macros, including main, then to avoid corruption, an altern...

Hi Miguel. Hover over the lower properties to show a drop-down. Select Add new Panel Properties.png The Cosmetic name will be TEST You can have spaces within the cosmetic name. The Property type you can select Single digital pin. The Property variable can be something like PIC_PORTB_RB2. Leave Visib...

Hi. I had a look at your flowchart. The interrupt component must be called only once, so it's best to place it before the main loop. That is probably the issue of why you are just getting 0? I would not recommend placing the Modulus function within an interrupt. It better to use interrupt_cntrl = in...

Thank you, Bob for the lovely comments. I really appreciate them. I do try and help as much as I can Thank you, Steve, that means a lot to me as well do all the lovely comments been made. You are right, of course, but also a must to be included are the rest of matrix staff. Without them, Flowcode wo...

Can you post your flowchart, please?
If I was you, I would make sure all the connections are sound and there is continuity as I have had O/C DuPont connections before.
If connections are all ok then what is the reply to

Do you have a spec for the LCD? Specifically, which drivers is it using?

Pin 7 or 8 are not available with the properties of the display ? pin7 is D7 and Pin8 is B0 as in the table I posted. Looking at your wiring diagram you should have: LCD pin connections.png As the diagram is not clear, can you state what pin of the Arduino (Digital 0 to 13)each connection of the LC...

Hi Martin. To me it looks like the wiring does not match the pins set within LED properties. Looking at your wiring diagram image, which is not very clear, you have the following: RS > D7 EN > B0 D0 > B1 D1 > B2 D3 > B3 D4 > B4 Within LCD properties It looks like you have EN going to D4 etc. Uno Dig...

Hi.
Can you post your project file (.fcfx extension), so we can have a look for you?

Hi. Thank you for letting us know I have fixed it so you should be able to now select the pins for I2C master and slave. Until the update is pushed, I have attached it so you can test sooner rather than later if you like to? In file explorer address bar, paste this: C:\ProgramData\MatrixTSL\Flowcode...

Note that i want to use software defined pins and not the default hardware pins. Does this make the difference and the program is not working at 1200? Yes, on V8 it does. Getting the baud to work at the correct rate for software on all targets is very time-consuming. For example, my target device i...

You don't need code for 1200 as that is not a custom rate, you just choose 1200 within UART properties.
Just make sure the timings are correct with a one-sec flasher test first.

Hi Bob.
Jumper wires will affect the readings because of the pin to breadboard strip resistance.
This is more so with smaller round pins than the larger square pins that are very common.
I have seen that effect when using an Analogue temperature sensor, smaller pin jumper wires and Sparkfun RedBoard.

Hi.
Can you post your flowchart and give us more details of the issue, please?
E.g not compiling, display staying on 0 etc.

Hi Enrique.
Happy new year & thank you.
It's really nice what you said, I appreciate it.

My English is good

Very good, well done.
