  Hello @HPC, I am not sure if I understand the problem. Can you please specify what is connected to what on via which protocol / interface? Thank you and have a nice day, Martin

  Hello @HVAC-Arthus First, I recommend downloading and installing the latest Mervis IDE and Mervis OS available here: https://kb.unipi.technology/en:files:software Then open the project in a new IDE and save to convert the project to the new version. Before converting to the new version, we recommend that you always create a project archive with a suitable name. If you use the RaspberryPi 4 computing module for Unipi 1.1 / Lite, this should also solve your problem, as support for these computing modules was added only in the last version. With my RaspberryPi 4 and Mervis v2.4.0 your project works.

  UART port (TX, RX) communication between Uni Pi 1.1 and Arduino Uno

  Hi Sabina, The best way to communicate between SW Mervis and third party devices is to implement the Modbus protocol on these devices. Subsequent operation and modifications are simpler and faster. Another great advantage is that this protocol basically allows you to operate multiple slave devices on one serial line. In this case, Openport is a functional block that takes care of opening the port, ie its reservation within the system. In the input string (def) for FB io.openport it is necessary to enter for UART port 1: "def: = 'serial: 1: 9600,8, N, 1';". I also enclose a tested code example in ST for Unipi 1.1.

  Hello @HPC, since Modbus doesn't know anything about data types, it is up to both the master and slave to come up with an exchange format. The registers are 16bit, but the ASCII is only 8bit. The data has to be aligned somehow, or maybe two consecutive characters can be stored into one register? Either way, the goal will be to iterate through the string and convert every item of the string array to byte. Best regards, Martin

  Hello, I just followed what you told me yesterday, but that doesn't change anything. In my .csv file, the values ​​that I save its data every second and not every tenth of a second ... For the use that I make of it, it is absolutely necessary that I can obtain more values ​​per second. PICOUL Mathurin

  As of now yes @lyngaas, until this gets fixed. Or you can create a function which does the recalculation properly. Best regards, Martin

  Dobrý den @Jan-Toth, toto bohužel není možné. Grafy v HMI pouze vzorkují hodnotu proměnné v čase a zobrazují dle nastavení poslední časový úsek. S pozdravem, Martin Kudláček

  Hello @Mathurin, I'm using the said SD card (without the HC) extensively and haven't encouter such behaviour, yet. Please, archive the whole Mervis project folder and send it to support@unipi.technology. I'll try to replicate the issue here. Also include the version of IDE you are using and the version of MervisOS image. Thank you and have a nice day, Martin

  Hello @kostastifki, we have experienced such behaviour with Avast antivirus, blocking access to the Mervis project files. Try adding and exception for the MervisIDE. Best regards, Martin Kudlacek
