@reitinge Hi Jan,
I set the execution time for reading and writing data from/to Arduino on 1s. After this change came only one error for five hours (see below). Before this, the mistakes came every second, which is progress. What does this error code mean? Are these error codes somewhere described?

I definitely began to think about at least that I would blame another way of 1-Wire sensors. How could I join the RaspberryPI proposed 1-Wire Port Hub? Is it a function block in the REXYGEN for it? This could improve communication with Arduino and use it only for binary I/O.

Thank you very much.

Hi,
I have another problem. I read 1-wire sensors from Arduino (see below). I always have only one 1-wire sensor connected per one pin. For 1-wire sensors I used Arduino pins 22, 23, ..., 33. I configured the Arduino_MEGA2560hex function block as shown below. In the REXYGEN Studio / Target / System Log, I get these messages (see below). The values ​​of the 1-wire sensors are read correctly. Yesterday the communication between RaspberyPI and ArduinoMega stopped working. I'm afraid it won't happen again (by REXduino I control the heating in the house). Because I found out according to the REXduino manual that this could be a poorly defined pin, I reconfigured pins 22, 23, 24, 25 as 0: Not connected. Then the System Log is error-free.
Why does this happen if these pins are reserved for 1-wire? I need to use them because I have a lot of sensors.
Thank you very much for your response.
Best regards
Michal

Hi,
the first reported authentication problem was solved by entering the password.
Then I performed the update to the last runtime 2.50.10.12932 (REXcore and REXYGEN) according to the instructions. The problem with slow during the application and communication between RaspberryPI and Arduino continued. It was strange that in an application with a lower version of the kernel, everything worked as it should. So I started checking the parameters of the function blocks with the SW version, where everything worked. I found out that for the function block "TASK - Standard task of the REXYGEN system" I have set the parameter "factor" to the value 10, the original value was 1. So I changed the value back to 1. Everything now works as it should!
Anyway, thanks a lot!

Hi,
I had a reported problem again. Then I found the latest version 2.2.0 on REXduino GitHub. I now have REXYGEN 2.50.9 and Arduino IDE 1.8.12 installed. The log system reports an error, see below. Inputs / outputs / 1-wire work, but communication between RasberryPI and Arduino is slow. Overall system responses are slowed. Finally, I tried according to the REXduino User Guide, chap. 5, in the serial monitor Arduino send a message c2, but I get back E11. That could be a problem, but I don't know how to solve it.
Please, give me an advice.
Thank you very much.

Hi,
I use REXYGEN version 2.50.10 on RPI with Arduino Mega - REXduino.
Question 1: I would like to ask whether it is possible to read different signal quality according to the example of connection with use of the VIN (Validation of the input signal) function block? It happens that some ds18b20 sensors are not of such quality or have a long line that they fail.
Question 2: It happened to me that after restarting RPI and starting REXCORE, the 1-wire sensor moves in the SW to another address / variable. Is it possible to somehow ensure that a unique address is assigned to the 1-wire sensor?
Thank you very much for the answer.
Best regards

Hi Jaroslav,
I downloaded REXduino Version 2.0.2. Everything now works without problems.
Thanks!
Best regards.

Hi Tomas,
I downloaded the new source code and translated it again. The translation is already without error. But communication between RaspberryPI and Arduino still doesn't work. Visualization works, but measurement data doesn't come and commands to peripherals don't work. There are still the same errors in the log as in the first post. In my opinion, it looks like a communication error over the serial line. RaspberryPI tries to communicate with Arduino, sometimes blinking led on Arduino, but not always blinking as before. The "Arduino_Mega2560hex" function block constantly lists the following states over and over: comm_status 1 then 2, err_code 0 then 49, err_subcode 0 then 52. I do not know their meaning.
Thanks.

Hi,
so i realized there could be a problem in that I updated RaspberryPI to the latest kernel version. So I probably need to install the latest version of Rexygen. The above information about the RexCore version is therefore incorrect (I don't even know where to find the RexCore version). So I installed the version Rexygen REXYGEN-2.50.10.12369-x64. After translation, some blocks were updated. However, I have error when translating and I can't find it.
Thanks.

Hi,
I have a problem with the software uploaded to RexCore. I have RexCore 2.50.9.10679 deployed on Raspberry PI 3B, NOOBS 3.4.0. A project created in Rexygen Studio uploaded to the kernel without errors. However, the SW works as if in slow motion / partially. The HMI runs, but the SW does not read the data. Below I attach an extract from the System Log. Please advise what the problem is. The SW is inserted in the appendix.
