Calculations with the numbers should be fine, it is just displaying for us humans that doesn’t work as expected.

Please keep in mind computers work in ones and zeros, not floating point numbers. As a result some floating point numbers can not be represented exactly and are a close approximation. Check https://floating-point-gui.de/ for an easy explanation or https://ece.uwaterloo.ca/~dwharder/NumericalAnalysis...

I've already heard it from you once...

Have you heard about signatures? That is mine. Has been for a long time. It will be displayed on all my messages on this forum, no matter what the content.

Sounds very complicated and you are not talking about programming a device, just updating a variable.

Consider using the TCP/IP component (or WLAN) to connect to a named (web)server to request the new value (use a unique ID for each device) and storing the information using the eeprom component.

You can certainly get the same level of support for software if you pay the same amount for it and a hefty maintenance fee. In all other cases it is a reality that software gets outdated and support stops. For Flowcode you can update to the current version and that one is supported (as is the previo...

Make sure the smps is one of the 'isolated' types so it does not share a ground with the circuit you are measuring. If it does share a ground you risk releasing magic smoke...

If you only need negative voltages and the meter can be powered by battery you could just use the circuits negative voltage as ground for the meter and the circuit ground as meter positive voltage. This won’t work if you power your meter from a power supply that supplies a ground equal to circuit gr...

Just wondering, why not connect the P1 signal to B1 and skip the additional components? Or connect an infrared detector/sensitive photodiode to the PIC to detect the coin?

According to the compiler warnings you are using floating point variables. Do you need floating point or would (long) integers be sufficient?

It helps if you tell what controller you are using. And post the flowchart you are experiencing issues with.

I get the RegMe.exe and I click YES, but still no success. I enter name and key, RegMe popup states it has accepted the name and key, I close FC% and launch it again and now I get message 16 days left... :( Are you running as Administrator? Flowcode needs to write to protected resources at activati...

It helps if you specify how large the program is and whether it uses libraries for hardware which might not be supported for by Flowcode.

Do you really expect help circumventing the license restrictions on the vendors official support forum?

Hi Jan, You are running out of memory which is not uncommon when using floating point as those libraries are relatively large. If there isn’t any code you can remove the ADC fix for the larger (memory wise) device is probably the only real solution. Sounds like a job for @Benj if FC7 is still being ...

Please use the V9 forum for messages concerning Flowcode 9.

Please go to the folder of your flowchart and look for the .msg file. Past the contents to a message. Your screenshot is illegible (for me at least).

Why do you post the same question on both this and the V9 forum?

For one wire you need a faster clock. However you could consider using the internal oscillator at high speed and switching back to the 32khz clock afterwards.

My worry when it comes to free software in the cloud is when will the business model change and all kinds of additional limitations be forced upon its users. This has been happing to a lot of ‘forever free’ software over recent years. Yes, it is still free but hardly usable.

Elektor is still available on paper. The digital edition is an additional format not the only option.

Any digital output pin should work. Don’t forget to initialize the pins to a known state at the start of you program. And to drive them to active mode when using the SPI component.

Could you post your failing program (flowcode source) so we can take a look at what might be the issue?

Your solution is not what Ben describes. An I/O pin is connected VUSB and has a pull down. Not VUSB is connected to GND with a resistor.
The question is of course which I/O pin...

This doesn’t make sense. If you have 4000 elements of 1 byte (let alone a larger integer) you need 4000 memory locations to store those values. None of the memory allocations in your output has 6 times 4000 elements = 24000 elements allocated. My guess is the lookup tables are truncated or the optim...

The amount of elements you can add to a LUT depends on the microcontroller you want to use. For 8 bit pic 50000 would be a huge amount and I don’t thing it can be done. For int alone that would be 100000 flash positions in flash.

Sorry to disappoint but the EB006 is for programming (certain) PIC controllers.
