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.

Hi Mike,
sorry for the late reply. To be honest, I haven't tried Monarco HAT with PoE HAT. However, by specification, HAT devices are not generally stackable. Monarco HAT should be powered by 10-30 VDC. PoE HAT supplies only 5 VDC. So I don't think it will work.
Cheers,
Jan

Hi Mike,
at the moment, it is really not possible to reactivate a license from a 32-bit OS to a 64-bit one. We are currently preparing this option and it should be available in the near future. I sent you an email with some additional information.
Cheers Jan

@mtomek Hi Michal,
I think you can track the PIN number where error occurs when you configure the system log, as described in the last point of the Troubleshooting section described here: https://github.com/jaroslavs/REXduino/blob/master/REXduino_User_Guide.pdf.

Cheers,
Jan

Hi Pedro, as far as I know, IEC 61850 in Rexygen is not supported in any way. If there is some Python library, it would be possible to use a Python block (documentation here: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/PYTHON.html#x276-27500016).

Cheers,
Jan

@relaxc Hello,

• C code has certain limitations in the REXLANG block. A detailed description of the block is available here: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/REXLANG.html#x274-27300015.
• Examples for using the REXLANG block are available in the installation. By default on the C:\Program Files\REX Controls\REXYGEN 2.50.10.13491\Examples\0203_Function_Blocks_REXLANG path.
• Compilation takes place only when translating the whole project in Rexygen Studio.
• Unfortunately, .so or .dll files are not supported in REXLANG .
• In REXYGEN, it is possible to call standard C language scripts with linked .so or .dll files. Scripts can be executed using the EPC block (documentation here).
• If you can use Python instead of C, take a look at the Python block (documentation here).

Cheers,
Jan

@mtomek Hi Michal,
according to REXduino_slave.ino, the errors mean:

49 52 - Error command - wrong pin number
51 49 - Serial bus buffer is full
49 50 - Error command - unknown command

Unfortunately, I can't say remotely what happened. Have this errors been repeated? Has there been an error 52 51 since the last time?

Cheers,
Jan

@pedrowirya Dear Pedro,
thank you for information. I'm glad, everything is working now.

Best regards,
Jan

@pedrowirya Dear Pedro,
please download the latest version of REXduino block library from git repository. You need to upload a new version of REXduino_slave.ino to your Arduino. Next, please copy the new version of the Arduino_UNO block into your REXYGEN project. The error should disappear. Also look at this thread, where a similar problem was solved.

Cheers,
Jan

@mikeyh Dear Mike,
we have published new REXYGEN pre-release version 2.50-next (2.50.10-13491) which is now available for testing. This version contains fix for the archive bug.

If you want to update your older REXYGEN-next version, just update and upgrade with

sudo apt update
sudo apt upgrade rexygen-runtime

Best regards,
Jan

@mikeyh Hi Mike,
I'm sorry, I tested deleting archives on our working version of REXYGEN, where this problem has already been fixed. I have now spoken to the main developer, who should publish a new version of REXYGEN-next in a few days.

I'll let you know when the new -next version is released. There, the problem with writing to the deleted archive will be solved.

Cheers,
Jan
