QUESTION

Usage example of pragma Task_Dispatching_Policy(Non_Preemptive_FIFO_Within_Priorities);

Asked 2021-Jun-13 at 17:46

I have a large, heavily task oriented program, and I would like to explore variant scheduler policies. I am using Gnat Ada 2020. In particular, I would like to set the tasking model by use of the pragma:

pragma Task_Dispatching_Policy(Non_Preemptive_FIFO_Within_Priorities);

I don't think I understand the actual usage very well. I understand what the pragma does, but I am having difficulty placing the pragma correctly, at least according to GNAT. For various combinations of placement in the following small program, I always get the error : "incorrect placement for configuration pragma "Task_Dispatching_Policy" I have tried outside of the whole compilation unit, within the task type spec, within the task body spec, etc. Can anyone show me an example of usage of this pragma? Googling found many discussions but no actual examples of usage in source code. Thanks in advance.

I am having difficulty placing the pragma correctly.

Focusing on correct placement, note that a Task_Dispatching_Policy pragma is a configuration pragma that must "appear before the first compilation_unit of a compilation."

at least according to GNAT.

As @egilhh comments, the GNAT User Guide describes how tp accomplish this in 3.4.1. Handling of Configuration Pragmas:

Configuration pragmas may either appear at the start of a compilation unit, or they can appear in a configuration pragma file to apply to all compilations performed in a given compilation environment.

In the case of a single compilation unit, simply place the pragma before the first context clause, as shown here:

how to send data to EEPROM from an interrupt routine

Asked 2021-Jun-06 at 13:26

I have an EEPROM AT24C256. I want to write to this EEPROM from Timer Interrupt routine. But when I try, STM gets stuck. It's not going on for other code rows.

ANSWER

Answered 2021-Jun-06 at 13:26

Many issues in this code:

The main one:

Do not use HAL_Delay() in the interrupt context. this function relays on the counter incremented in sysTick interrupt which can have lower priority.

Secondary: 2. Do not use any delays in the interrupt routines.

Try to do not call functions that execute a long time. Do not call any HAL_ unless you are sure that they do not use HAL_Delay
uint8_t buf2[50] = { 0 }; is a local automatic variable.

Trait bound not satisfied in function argument

Asked 2021-Jun-05 at 14:56

I'm running into an issue with trait bounds and can't understand what I'm doing wrong. I'm working with the arduino-uno crate from avr-hal and I have a function that reads the ADC, implemented as follows:

...

ANSWER

Answered 2021-Jun-05 at 14:56

The compiler error says:

the trait bound &mut T: avr_hal_generic::embedded_hal::adc::Channel is not satisfied

Notice that the error is asking for &mut T to implement Channel, &mut T: Channel<...>, whereas your T has the bound T: Channel<...> — applying to T itself rather than &mut T. That's why the bound you've already written isn't helping.

Now, what's the right fix? If I look at the docs you linked, I can find the type of ::read. (Note: I copied the text from the docs to construct this snippet; I didn't read the source code.)

Python Function - Looping through dictionary and updating value

Asked 2021-May-27 at 12:27

I'm having an issue wherein i'm trying to loop through a dictionary to update all the values based on a specific input from a user.

I've posted my code below, basically, the user inputs a number into the different lanes played input boxes, and the function should update the dictionary to contain the values input by the user.

the loop doesn't seem to be going through every key in my dictionary, only returning the first value and then seemingly skipping the rest.

I am only 3 weeks deep into a python tutorial and I'm not really sure what i am doing wrong here.

please see code below :

ANSWER

Answered 2021-May-27 at 12:10

It's because of bad indentation in your code. The return keyword is hit at the first iteration of the for loop, which makes your function stop.

This works, since return happens after the whole for loop:

How to manage service account key json file for smart home

Asked 2021-May-21 at 16:56

I'm currently building out a Google Home project in NodeJs that has a fulfillment service that uses a downloaded service account key. This key is deployed with my fulfillment service to my firebase function.

I'd like to avoid storing the key in an environment variable and I would absolutely like to avoid other members of my team needing to downloading a new key for deployments.

I see with some google services you can use ADC to automatically get the service credentials but I can't seem to find a way to get the same information as the json file through the google-auth-library.

Is there a way to initialize the smarthome service from the actions-on-google-nodejs library from the service account assigned to the function?

Answered 2021-May-21 at 16:56

For anyone looking for an answer to this, it's been a couple months and it seems Google has included requestSync and reportState into the googleapis npm package (that or I completely missed it before). This package no longer requires a service account key.

The second parameter to HAL_UART_Transmit is a pointer to the data and the third is the size of the data.

If you want to transmit binary data on the UART you need to change value, 14 to &value, sizeof value.

If you want to transmit ASCII text then you need to do something like:
