QUESTION
I have a Blazor site, I am using an HTML template that has CSS and JS for styling.
I have imported the assets into the wwwroot, and I have made a reference to them in the _Host.cshtml file; The styling and certain elements seem to be working... However I've noticed the animations and other portions of the javascript are not working as intended...
For example, I have an accordion, and it doesn't expand or close.
I made the same page in an HTML format and put that in the wwwroot... When I run the code and navigate to that page, it seems to be working just fine. But on my razor page, it is not...
This is it on the .razor component
This is it on the .html file I made in the wwwroot
_Host.cshtml
...ANSWER
Answered 2021-Feb-10 at 18:19Good afternoon,
From my experience calling Javascript in a Blazor Component requires use of the IJS runtime. Here is the Microsoft Blazor Documentation for this issue:
https://docs.microsoft.com/en-us/aspnet/core/blazor/call-javascript-from-dotnet?view=aspnetcore-5.0
Essentially you use the IJS runtime to call specific methods from your custom JS documents.
QUESTION
I am using STLink V3 set to program the F103RB Nucleo board using SWDIO interface. The board works fine when connected to PC using the on-board STlink debugger but when I use external STlink device to program it, it says "Can not connect to target!". I have removed on-board STlink debugger jumpers so that I can use external one. My connection from Stlink V3 to F103RB Nucleo (CN4 Header)
are as follows:
Clock->Clock, GND->GND, SWDIO->SWDIO, NRST->NRST,VCC->NOT CONNECTED (Even if I connect, it doesn't work)
The datasheet says that "SB12 NRST (target MCU RESET) must be OFF if CN4 pin 5 is used in the external application", is this the problem ? How to resolve that ? or is there any other potential reason for this error.
I'll really appreciate prompt responses. Thanks
...ANSWER
Answered 2021-May-28 at 08:22CN4 connector is connected to on-board ST-LINK, which is used when you use on-board ST-LINK to program/debug an external device.
You need to access pins of the main uC using other connectors.

QUESTION
I am trying to send some commands to a Terminal through UART, so in order for the MSP430 to know which command he got, I wrote some if-conditions in case cREC_BUFFER contains a certain word, the microcontroller should controller it then, for example if the string cREC_BUFFER contains the word "ENDE" at the end, he should go into the if condition inside. The problem that I am facing, is that when I check what the string empty string cREC_BUFFER has after debugging, it contains only the last character "E" of the word "ENDE". Can someone tell me what mistakes I am making here? Thanks a lot for the help in advance! (I reduced the length of the code in here by deleting the content of the other functions, since they do not cause the problem)

QUESTION
I am learning to use the STM32F302R8 board and I have this problem.
TIM2 is configured with toggle output CH1 on PA0. (This works fine).
TIM15 is configured as input capture CH1 on PA2.
I have a jumper between PA0 and PA2.
The aim is that when TIM2 reaches the value of CCR1 it triggers the PA0 pin, which happens, and having the jumper with the PA2 pin should trigger the TIM15 input but this does not happen.
The while that checks the CC1IF flag never ends, it doesn't detect anything.
What can it be?
...ANSWER
Answered 2021-May-05 at 08:08I moved the clock trigger lines to the beginning of the code and instead of PA2 I use PB14 and now it works fine.
QUESTION
I'm trying to communicate with TMC2209 (stepper drive) with an Arduino nano Every. I connected pin RX on pin D2 and TX on pin D3. I placed a 1K resistor between TX and RX. It seems I can write parameters (even I'm testing this deeply, I'm not so sure now..) but I'm not able to read nothing from driver.
Picture added 15/04/2021 related to datasheet of TMC2209
In my test, I tried with only one driver with address 0, means MS1_AD0 and MS2_AD1 connected to GND.
...ANSWER
Answered 2021-Apr-15 at 22:25I found! The issue was the handling of "software" serial port. Unfortunately I was confused because many examples of "TMCstepper.h" library are shown using two pins as TX and RX, so I was convinced internally pins were handled to send and receive.. but it's not.
So solution I found is:
QUESTION
I have a Raspberry Pi Compute Module 4 with eMMC, I'm able to flash from my Ubuntu host the eMMC following the instructions using
- rpiboot
- Imager
I have flashed a SD card using the tool Imager, but when I introduce it in the slot, It is not booting from the SD but from the eMMC. I have used a Jumper in J2, to disable eMMC boot, but nothing happens, and if I remove the Jumper the board boot from the eMMC. How can I make it boot from SD?
Thank you for the info.
...ANSWER
Answered 2021-Apr-13 at 00:11I asked this question in the RPi forum: "If I have a CM4 with eMMC plugged into a I/O board, can I put in jumper J2 to disable eMMC boot and boot from a microSD instead?"
Here is the answer I received: "the module with an eMMC doesnt have the SD pins wired up, so the microSD slot on the CM4IO board is going nowhere. you could add your own microSD on the right gpio, but the firmware doesnt support booting from it"
And another answer: "You end up booting to USB mode rather than SD Card - this is a fall back if the eMMC gets corrupted somehow."

I have a dataset listing general items bought by customers. Each record in the csv, lists items purchased by a customer, from left to right. For example (shortened sample):
...ANSWER
Answered 2021-Mar-06 at 14:21The count in the case class should be an integer... and if you want to keep the results as an RDD, I'd suggest using reduceByKey rather than countByValue which returns a Map[String, Long] rather than an RDD.
Also I'd suggest splitting by , rather than , to avoid leading spaces in the item names.
QUESTION
In this situation I tried to do the level menu, but this.innerText doesn`t work
...ANSWER
Answered 2021-Feb-25 at 20:51item.addEventListener('click', () => levelJump()); should be: item.addEventListener('click', levelJump); because in an arrow function, this binding is not altered from what it was outside of the arrow function and you need this to be bound to the item element that causes the click event to be triggered.
QUESTION
I'm having trouble with a python script running on an RPI0 reading serial input from an Arduino. I know the Arduino's code is correct as everything works as intended interacting with the Arduino over the built in serial monitor in the Arduino software(send code a10(code to drive a relay HIGH), Arduino sends back 11(basically asking for how long), send code b5, Arduino will hold pin HIGH for 5 seconds(b5)).
However when I attempt to read any serial input in python using the pyserial module, nothing happens. I know it does successfully send the code to the arduino as it will hold the pin HIGH for the specified seconds when I rewrite the python script with ser.write("a10b5").
The serial connection is NOT USB. I'm using jumper wires with a voltage shifter in between them using the Arduino's and Pi's GPIO TX and RX pins.
- using python -V in the terminal it tells me I'm running version 3.8
- I've tried multiple baud rates(300, 1200, 9600, 57600) with no change in behavior
- I've also tried changing if x == 11: to if x == "11": in case for some reason it was receiving strings and not ints, also to no avail.
Here is the code:

Install jumper
You can use jumper 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.
