QUESTION

Errors compiling sqrt function for RaspberryPI2 and BeableBoneBlack with arm-none-eabi-gcc compiler

Asked 2020-Dec-06 at 05:05

i'm new in this type of coding and i'm trying to do some test executing bare-metal software for Cortex-A processors. I have experience with Cortex-M MCU and i compiled code with an IDE like ARM-Keil and with SDK by Nordic for some BLE jobs. Now i want to try to understand better the world of Cortex-A and i would learn coding in a bare-metal way, starting from some examples that i found online. I had some experiences with freeRTOS with Cortex-M, so i found online some git repository from some good guy that makes a porting of freeRTOS for RaspberryPI and BeableBoneBlack. From now on i will just explain my problem for the BeableBoneBlack, beacouse for the RaspberryPI it's similar.

I'm on linux, i installed gcc-arm-none-eabi compiler, so i cloned the BeagleBone Black with freeRTOS repository from this link.

I usually use VS Code to write code, so in the integrated terminal when i run the command make everything it's working and the of my BBB flashes correctly. So now i would like to improve my code, and in order to do some tests i would like to use the rand() function, from stdlib.h. Unhappily I find that there are some errors: undefined reference to rand. The last months, before doing tests with the BBB, i found other repos for RPi2 and i learn something about the linker of the arm-none-eabi compiler, that needs the addition of some parameters in order link library files during the process. From this repo now i have two files: makedefs_ti and makefile. Opening the make file i found in line 26-27 the part of the generation of the file app, so where the linker is called. In this lines there are references to LIB_GCC and LIB_C, which are defined in the makedefs_ti. In lines 49-50 there are the references to the directory where the compiler is installed (I changed 4.7.3 with the correct one installed on my linux pc that is 9.2.1). In the makefile, after -L$(LIB_C), if i add the linker parameters like -lc or -lg and try to recompile, i had error like arm-none-eabi-ld: cannot find -lc. With some understanding from online resources i modified the the makedefs_ti as following:

QUESTION

How to do a single logistic regression with multiple data frames?

Asked 2020-May-12 at 03:48

The goal is to make a single ordered logistic regression using multiple data frames with the same structure.

In the example below I joined two data frames to be able to do a single ordered logistic regression. However, I would like a solution that automates the process, since there are 417 data frames.

The i in your loop is not the data. It's the index of the character vector you created outside the loop. But be careful assigning the name to data as you then create one more item in the for loop! Best to rename that. Your other problems are that you never save the results of each model, only the last one. So use a list to save them all and then lapply to extract them.

QUESTION

How to get a list of all topics containing specific values known to MQTT broker?

Asked 2020-Feb-19 at 19:05

I'm looking for a way to get a list of all topics known to a broker. There are some quite similar question's, but they didn't help me to figure it out for my use case.
I've got 3 Raspberry Pi's with multiple sensors (temperature, humidity) which are connected over an MQTT network. Every Pi has it's own database containing time series of measurements and other system variables(like CPU).
Now I'm looking for a way for the following szenario:

I want to monitor my system and detect anomalies. For that I want to get all sensor-time series in the last x seconds and process them in a python script. My system to do the monitoring calculations can be every Pi.

Example: I'm on RPI2 and want to monitor the whole distributed network. There's no given knowledge about the sensors attached to the Pi's. Now from my python script running on RP2 I would initalise a MQTT client and subscribe every sensor data on the broker.
I know about the wildcard # but I'm not sure how to use it in that case. My magic command would look like the following pseudo code:

First, your wildcard topic patterns are not valid. Topic patterns can only contain a single '#' character and it can only appear at the end of a topic e.g. foo/bar/# is valid, #/foo is not. You can use the + character which is a single level wildcard character.

This means a topic pattern of +/sensor/# will match each of the following:

rpi1/sensor/foo
rpi1/sensor/bar/temp

but not

rpi1/foo/sensor/bar

Next brokers do not have a list of topics that exist. Topics only really exist at the instant that a message is published to one, the broker then checks the patterns that subscribing clients have requested and checks that topic against the list and delivers it to the clients that match.

Thirdly when bridging brokers in loops like that you have to be very careful with the bridge filters to make sure that messages don' end up a constant loop.

The solution is probably to designate a "master" broker and bridge all the others one way to that broker and then have the client subscribe to either '#' to get everything or something more like '+/sensor/#' to just see the sensor readings.

Vulnerabilities

No vulnerabilities reported

Install rpi2

You can download it from GitHub.
You can use rpi2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
