I needed to insert a TextField to search/filter records, but I don't know what's going on.

When I click on the "Cães" option of the BottomNavigationBar, on main.dart,

I only get a CircularProgressIndicator and the data does show up.

Have any of you experienced this problem?

Does anyone know why my Listview doesn't show up?

I am trying to simulate the PIC16F84 and now need to implement PCL / PCLATH registers.

The PIC16F84 has 1K of Program memory.

The PCL is 8Bit wide, so in this case Bit 0 and 1 of PCLATH is used to switch between the four Pages each having a size of 256B, am I right so far?

Based on this, I do not understand the following:

The Datasheet states for a GOTO:

The upper bits of PC are loaded from PCLATH<4:3>. GOTO is a two- cycle instruction.

But aren't the upper Bits of PCLATH too much? I mean there are only 4 Pages, each 256B, hence only bit 0 and 1 of PCLATH are needed. Or in other words - Bit 3 and 4 of PCLATH are always 0 ? Why would I then need to care about 'PCLATH' when performing a 'CALL' or 'GOTO' ?

I have a ModelForm for a model that has a couple of files and with every file, a type description (what kind of file it is). This description field on the model has CHOICES. I have set these file uploads and description uploads as hidden fields on my form, and not required. Now the file upload is working, but the description is giving field errors, the placeholder in the dropdown is not a valid choice, it says. That's true, but since it is not required, I would like it to just be left out of the validation and I am stuck on how.

My codes, shortened them up a bit to keep it concise.

models.py

here is my txt file that has contained all of the lines. What I want to do is create a dictionary, and access a key, and get a list of values

I have a repository based on "https://github.com/MicrochipTech/amazon-freertos.git", I have pushed this to my own repository, which is not in Github so I believe fork is not possible. In my newly created copy I have added my application files as well as some changes to the amazon source files. This is committed and pushed to my private repository.

When the amazon repository eventually changes, is there some way that I can merge those changes into my repository, yet keeping the changes i have made to the previous version of that repository? Note that I will have modified some of the files that are part of the amazon repository so I cannot simply have it as a submodule.

Edit: As suggested I have:

So i wanted to make a timer on the atmega328p µC using the CTC Modus. The idea was, that every 10milliseconds when the interrupt function is called , in that function i schould increase a variable millisekunden by 10. and once it reaches 1000 it schould be printed out . The datasheet can be found here: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-7810-Automotive-Microcontrollers-ATmega328P_Datasheet.pdf With registers i can change the Mode to the CTC Mode and set up the right Prescaler on the timer. It is a 16Mhz CPU. So the formula is : T_clock * Prescaler * OCR0A = time( unit is seconds) So i calculated: (1/ 1610^6) * 1024 * x = 1010^-3(i wanted 10 milli seconds). and x is then 155. With the bits CS00 and CS02 i set up the prescaler to 1024. OCR0A was then set to 155 as the formula says. CTC mode was enabled by setting the BIT WGM01. And the last thing was that i increase the variable millisekunden in the interrupt function. For some reason it doesnt want to work. Can anyone pease help me?

I'm trying to do a very simple program using ARM Thumb assembly, which will turn off the LED on my Arduino Due (The ATSAM3X8E pin linked to it seems to be pulled up internally by default). I'm doing this as a test before doing more complex things in assembly.

I've placed the inital SP value as well as all 15 mandatory system exception vectors in a section, and did a quick GPIO hardware registers initialization routine (Defines the pin as an output I can write to, disables the pull-up, so as long as I don't actually write into the output data register the output pin should remain off). (I didn't do any RAM loading routine because I don't have values other than read-only constants in the program at the moment, so no data section too).

I used the GNU Assembler, ld with a simple linker script that ensures the vector table is at the very beginning of the binary file, did a quick objcopy from the elf and got a nice raw binary that I flashed in the internal flash of the MCU using the BOSSA command-line. (See code below)

But nothing happened, the LED stayed high.

I have a class like the following:

I've been trying to find a solution to get amazon-freertos to detect WIFI network down so I can reconnect. I have to say I am still not fully in understanding of how it all should work.

From reading up it looks like the intended way is to wait for callback to vApplicationIPNetworkEventHook where the programmer should implement necessary reconnects. However the problem is that this callback function does not get called for network down events, it only get called for network up events.

Reading FreeRTOS guide I see that for vApplicationIPNetworkEventHook to get a callback for network down event the underlying driver must first tell the TCPIP stack of this event, and it goes on to say not all drivers implement this, so I think I have located the problem now.

My question is how should the driver inform the TCPIP stack? The driver logs the network down event (it doesn't do much more than that) so I can add some code there to alert the TCPIP stack, but how should that be done? I cannot find any instructions for how to make this change, any help or suggestion is much appreciated.

To add I think this should be the place (iot_wifi.c) to implement it:
