I have created an empty project where, after 5 second from startup, I execute the line of code
HAL_PWR_EnterSTANDBYMode();
The micro still use 18 micro ampere. The datascheet says that it shoult requeire less than 1 micro amplere.
Is the function
HAL_PWR_EnterSTANDBYMode();
enought or have I to do something elese in order to reduce consumition at minimum?

I'm having an issue configuring passing time on an Anylogic model: I would like to configure every tick of the model time to be 5 minutes at 1x.
To be clearer, all the things I did were done on the project components shown on the "Projects" tab.
Reading guides and manuals I saw that by clicking on the project root I could configure the time unit in minutes, and this allows me to run it with 1 minute per tick.
I tried to modify the Simulation options setting the "Real-time with scale" at 5, but when I run the experiment it automatically starts at 5x.
Is there any way to achieve my needing?
Thanks a lot.

No matter what, the best option to control this, is by doing it programmatically.
getEngine().setRealTimeMode(true); // to be sure you are not using virtual mode
getEngine().setRealTimeScale(5); // 5 would be the 5x, otherwise put a different number
For instance, you can run this at 1x when your model starts (on your "on startup" action on your main properties) and with a button, or after some time, you can change it to whatever you want.
I've been given a task to set up an openai toy gym which can only be solved by an agent with memory. I've been given an example with two doors, and at time t = 0 I'm shown either 1 or -1. At t = 1 I can move to correct door and open it.
Does anyone know how I would go about starting out? I want to show that a2c or ppo can solve this using an lstm policy. How do I go about setting up environment, etc?
To create a new environment in gym format, it should have the 5 functions mentioned in the gym.core file.
https://github.com/openai/gym/blob/e689f93a425d97489e590bba0a7d4518de0dcc03/gym/core.py#L11-L35
To lay this down in steps-
Define observation space and action space for your environment, preferably using gym.spaces module.
Write down the step function which performs agent's action and returns a 4 tuple containing - next set of observations from the environment , reward ,
done - a boolean indicating whether the episode is over , and some extra info if you want.
Write a reset function for the environment to reinitialise the episode to a random start state and return a 4 tuple similar to step.
These functions are enough to be able to run an RL agent on your environment.
You can skip the render, seed and close functions if you want.
For the task you have defined,you can model the observation and action space using Discrete(2). 0 for first door and 1 for second door.
Reset would return in it's observation which door has the reward.
Then agent would choose either of the door - 0 or 1.
Then perform a environment step by calling step(action), which will return agent's reward and done flag as true - signifying that the episode is over.
Frankly, the problem you describe seems too simple to accomplish for any reinforcement learning algorithm, but I assume you have provided that as an example.
Remembering for longer horizons is usually harder.
You can read their documentation and toy environments to understand how to create one.
I am running a ros publisher/subscriber node, which receives a single image from a /image_pub topic , do some processing and publish the results on /results topic. The image_pub topic is publishing at 20Hz but my publisher/subscriber node runs at 12 hz(i found it using rostopic hz /results). Is there any way to improve the speed or tell my program to run at 20Hz. At start it was running at 20Hz. Then i turned off my Linux for lunch, came back and restarted my program. Now its running at 12 hz. I have restarted it again and again but still runs at 12 hz. Any solution..?
If your image processing takes longer than 1/20 second than there is no way you can achieve the 20Hz. If that is not the case then the following main loop will do the job
ros::Rate publish_rate(20);
while(ros::ok())
{
// do some processing
publisher.publish(image);
publish_rate.sleep();
}
The ros::Rate will make sure to sleep for the right amount of time to achieve the 20Hz.
Also make sure to compile in Release mode (catkin_make -DCMAKE_BUILD_TYPE=Release) as this will speed up you code by a good margin.
I have created task on controller and there is loop which is loading for 100 times.
Now I want to load it for 25 times and pause that loop for 1 min and after that it will execute next 25 items same for next 25.
I have checked it with sleep but its not working.
Can you please advise me if is there any way on plugin event or any other method.
Thanks
This is actually unrelated to Joomla! Since you're creating a long running process you need to start it with something else than a browser. A CRON job is a good idea here if you want to execute this operation multiple times. Otherwise it can run via command line. Make sure the max_execution time setting of PHP does not cause any trouble.
If you still need this within Joomla please have a look at the CLI documentation.

When I create a new quote from Epicor I would like to add an item from the parts form automatically.
I am trying to do this using the following ABL code which runs when 'GetNewQuoteHed' is called:
run Update.
run GetNewQuoteDtl.
run ChangePartNumMaster("Rod Tube").
ttQuoteDtl.OrderQty = 5.
run Update.
I am getting the error:
Index -1 is either negative or above rows count.
This error occurs for each line in my ABL code.
What am I doing wrong?
That's not the proper format for a 4GL error message (nor is it at all familiar) so I'd say it is an Epicor application message. Epicor support is probably your best bet. However... Just guessing but it sounds like you might need to somehow initialize the thing that you're updating.
Agree with #Tom, but i would also say try and isolate the error and see where the error is raised as soon as you find the point the error is actually raised it is normally much easier to figure out exactly what is going wrong and how to solve it.
Working between a 0 based and a 1 based system there can be issues with the 1st or last entry depending on which way you moving. As the index for 0 based systems starts at 0 and ends at n-1 where 1 based systems start at 1 and end at n.
