Hi Bruno,
the Monarco HAT has hardware PWM and therefore does not need to create PWM in software using a PWM block. Documentation to the PWM on Monarco HAT can be found on page 16 in Monarco technical specification https://www.monarco.io/docs/Monarco-HAT-Hardware-Reference-Manual.pdf.
All you need to do is set the PWM frequency (in your case to 50 Hz) and calculate the actual duty cycle for one channel according to the equation:

Duty_cycle = pulse_width/period_length

Take a look at example 0121-05_Monarco_HAT_PWM_output to find out how to set the frequency and duty cycle for PWM1 (for example).

Hope, this will be helpfull.
Cheers
Jan.

Hello,
we have released image with the REXYGEN 2.50.10-next (2.50.10.13233) which is available in our official repository.

@mtomek Hi Michal,
you are welcome. I'm glad the problem has been fixed.

Cheers,
Jan

Hi Mike,
you're right, RTC will be better than UTC. Unfortunately, it is not possible to set RTC via Diagnostics (at least as far as I know). However, if you can connect to Monarco via Diagnostics, you should also be able to connect via Putty to the Terminal and set RTC via

timedatectl set-time "2015-01-31 11:13:54"

Or is I still missing something?

Kind regards,
Jan

Hi Mike,
the easiest way to set the RTC is using terminal command timedatectl:

timedatectl set-time "2015-01-31 11:13:54"

Otherwise, you can use the Date and Time tab in DWM.

The most complicated solution is to use the DATETIME block. Set the isetmode parameter to 6 (this isn't documented yet). Set requested time in seconds from 1 January 2000 on the usec input and apply a leading edge to the SET input.

Cheers,
Jan

@mtomek It occurs to me that you do not have the latest version of REXduino block library. The Arduino_MEGA2560hex block should have the last input and output named userSendV and userRecvV. Please, download the git repository and look into REXduino_master/Examples/51_MEGA2560hex_IO.

If you downloaded the new version of REXduino recently, you should replace the original Arduino_MEGA block with a new one. Also, please update the REXduino_master.c script and upload a new REXduino_slave.ino sketch into Arduino.

@mikeyh Hi Mike,
thanks. There is REXYGEN 2.50.10.12481-final on the image (official release) but it should be more or less compatible with the REXYGEN 2.50.10-next (currently at version 13233). But we want to make the special image with the REXYGEN-next.

Cheers,
Jan

@mtomek Hi Michal,
it seems that the problem occurs when REXYGEN sends some user data to Arduino and Arduino responds. Are you using userSendV input of the Arduino_MEGA2560hex block?

Cheers,
Jan

@mikeyh Dear Mike,
we have finally published the DWM documentation, which you can find here. If anything is unclear or doesn't work, please let us know.

Kind regards,
Jan

Hi Bruno,
sorry for a late response. Could you please post here a print screen of your ARC and TRND blocks properties? I assume that you have RexArc installed on your device with command sudo apt install rexarc
and you export data from the archive to CSV using a command in RexArc (please, correct me if you are using different approach). Could you please copy this command as well?

How much difference is there in time stamps? Can't it be caused by a wrong set time zone? In the ARC block, there is a parameter ldaymax. This parameter set the maximum size of archive per day (see doc here. This could be the reason why some data is missing.

Best regards,
Jan

@pancirm Hi Michal,
I just tested AI1 and AI2 on our UniPi v1.1 and REXYGEN 2.50.10.12481 and everything seems to work. Do you have the possibility to test the same configuration on a different UniPi 1.1? Alternatively, could you try to reinstall the current UniPi using the instructions from here? To install Rexygen with the UniPi 1.1 driver, I used the following instructions on a fresh raspberry image:

wget -nc https://download.rexcontrols.com/scripts/rex-install-unipi1_1.sh  
chmod +x rex-install-unipi1_1.sh  
sudo ./rex-install-unipi1_1.sh
