So i am building a website where i want to implement a add banner form when the User can Upload his banner image as banner Profile.

And here is where the problem i raise, when i run the code, it return always as null.

Here is my controller:

I came to this forum because I have a question about my project. I have to make a memory game for school and this has worked out quite well. But now also want to add time. The maximum time a user has to push a sequence. When this time has elapsed --> GAME OVER. I've already tried to work with the mills function myself. But now I've noticed that my function Get_sequence actually stops my Mills function. I think this is because of my Get_Sequence function and the while in it. Now, I've tried to get that mils function in the Get_sequence function. And I put them in other places, but right now I'm a bit stuck. If anyone knows a solution to this problem, I'd love to hear it! Thank you so much Barballon

(Arduino code and C++ is also totally new to me, so if the solution is simple don't attack me please XD.

I'm currently having trouble getting my Ionic 5 along with Angular 9 project to work.

ionic cordova run android works great

but as soon i run ionic cordova run android --prod the only thing i get is a blank screen.

I'm trying to build a small hygrometer based on the DHT11 and I'm having a bit of an "issue" with the code size. I want to run it on an Attiny45 and it's a wee bit too big (352 bytes too big to be exact). I am aware that I could just use an Attiny85 and have space to spare or don't use a bootloader and barely fit it in (94%) but I kind of want to make my life harder than it needs to be and figure out how to reduce size since it'll probably come in handy in the future. Treat it as a learning experience if you will.

What it's supposed to do:

• Read DHT11 input
• Display results on 2 two-digit 7-segment displays (so I guess 4 7-segments in total)
• Go to sleep most of the time to preserve battery
• Wake up every 8 seconds to update sensor values (without turning on the display)
• Wake up on a button press to display the values for humidity and temperature

Side note: 7-segments are adressed via two 74HC595s of which I am using 7 outputs each for the displays and 1 each for a transistor that connects the display in question to GND. There's a schematic at the bottom if you're interested.

As pointed out, my main issue is code size so if anyone has any tips on how to reduce that (or any other tips how to improve the code) please let me know.

I hope I'm asking the question properly, if not please let me know.

Tried to save the picture taken from ESP32Cam module, into SD Card as JPG file but it fail to open in Windows.

I have followed the code to take picture as is present at the below link: https://github.com/espressif/esp32-camera/blob/6a9497bbe909165663d958986e621e98dabcf994/examples/main/take_picture.c

After taking the picture I am converting it to jpg file using "frame2jpg". The camera used is OV2640. After conversion I am saving as.jpg file in SD Card. The SD card I moved to Windows PC and tried to open the saved .jpg file, but it does not open. It gives a message that file in not recognized.

Do I need to do more than just "frame2jpg" to convert it in right format?

I have two raspberry pi with almost identical setup. On both I have a systemctl service and a timer which run every 15 seconds. The job calls a go script, which reads out the system temperature and creates a log entry in my mariadb database. The database is running on one of the raspberries. Therefore the only difference in the two go scripts are the hostname of the database and an identifier variable so I can see in the database from which the database entry is coming from. The rest is identical.

The problem is that raspberry1 produces more database entries than raspberry2. When I start with a fresh database with zero entries. Then 1 have about 120 entries from raspberry1 and about 70 entries from raspberrie two. The error continues. After more time I get for example 1000 entries and 700 entries.

Does anyone know where the differences could coming from? Maybe when both jobs want to create a new entry in the mariadb at the same time? But I'm almost sure that this is handled somehow by mariadb.

Here are the details:

FanLog.service

I try to activate a timer at the first detection on falling edge of hardware interrupt detection and to deactivate the timer after 8 runs. But when I stop the timer, the hardware interrupt triggers again and starts the timer immediately.

In the image you can ignore the blue signal. The purple signal is timer1 toggling the pin. Green is hardware interrupt toggling the pin.

All it has to do is trigger at the first falling edge, then toggling a pin in a period of time.

My question is: why does hardware interrupts trigger twice?

I would like to enable EXTI interrupts in order to have information on whether the port has changed its state. As you can see below, I've configured 2 pins, GPIOA5 and GPIOB3. Both have been configured with pullup resistors, so they should change state when they are connected to the ground.

The problem is that everything works for GPIOA5 but doesn't work for GPIOB3. The isr for GPIO5 is being called, but for GPIOB isn't.

I commented part of code regarding UART configuration as it's not relevant in this case - uart works fine, so I can see messages going out from MCU.

What could be a problem here?

I'm using STM32f411CEU6 and libopencm3.

I have an STM32F429l-DISC1 board.

I'm trying to read the value on pin PC11. This is the PORTC settings:
