Good evening! I will be able to find out if it is worth using the atmega328p chip only on Wednesday, after 13 o'clock. If everything goes well with you, then I will be able to purchase it on this day and try to connect and check it.

Good evening! Yes, I looked in the store, they have such an atmega328p chip for sale, my programmer will be able to program it-I just looked at it, and the FC program and your knowledge, skills, abilities and desire to help developers of different levels will help me make future projects. And chasin...

Good afternoon! The solution for receiving and transmitting data over wi-fi using the esp8266 module can be used in several projects (if of course it turns out) in one, data will be transmitted and written to memory without the ability to view them during reception, in another case they can and will...

Good evening! I am now in the throes of choice, I found pic controllers that will fit into the already soldered DIP28 panels, I also found them with even fewer pins and suitable functionality. But since you say that using two controllers is not a good idea, so I also reject this idea. In addition, p...

Good evening! Yeah, I see-in other words, I need to look at what we have in the store, and you see if these controllers will bring any surprises. And you say that you cannot use any adapters between the controller and the esp8266 module. I meant that in some tasks the esp8266 module will work quite ...

Good morning! I was also thinking about newer versions of the FC program today...but I thought it was a good thing that I didn't buy them, there would be the same jambs in the program, but for a lot of money and maybe a better interface. Yes, I downloaded version 10, but did not install it. We have ...

Good evening! And here you can see what errors occur during compilation, maybe something is not working correctly?

Good evening! Unfortunately, there are no changes for the better. There is a signal on the Tx pin, there is no signal on the B1 pin, the LED does not blink. I don't have any new program updates. I tried to change the parameter of the esp8266 module. There is a setting for how commands end, it usuall...

Good evening! I really liked your phrase about tires and gasoline, it's funny, but it often happens in life. I will now attach a program to you where, as you said, the graphs look beautiful, but once again I want to say that there I use the uart module in the program, but I can't get good results wi...

Good evening! As for the configuration of avr controllers, here is one of the few links to online resources to quickly set the desired values and not bother reading the instructions too much.: https://www.engbedded.com/fusecalc/

Good evening! Thanks for the hint, but I have never used the FC program settings to program the controller's operation parameters (except for setting the frequency of the crystal in the program), because some kind of special programmer is needed there. And I had TL866CS when I bought it, then I chan...

Good evening! In general, if you look from the side of a person who has not used the FC program, but understands a little how the technique works, at the sight of our experiments on sending the letter "U" using the esp-01 module only from the program, but in reality this module is not connected and ...

Goodnight! I was looking for the moment when you said about May 22 that everything worked there. Unfortunately, I did not find the features of that assembly on the board, but most likely the esp-01 module was connected to the adapter board and, accordingly, to the controller. And then you said that ...

Good evening! You wrote about the possibility of the atmega8 controller operating at a frequency of 16 MHz, I have heard about this possibility, but I do not know how to turn it on...I use an online fuse calculator for avr controllers and there is no such feature there either.

Good evening! Unfortunately, the quantity has not turned into quality. In all the tried programs, the signal was visible only from the Tx output, from the B1 output where the LED was connected-nothing came. I tried sending the "U" symbol at the end of the program and at the beginning of the LED flas...

Good afternoon! Unfortunately, the version about 8 MHz has not been confirmed. The signals are the same-there is a familiar signal on the Tx pin, but there is nothing on the pin where the LED is connected. But then another creative idea was born, but what if sending the "U" symbol was done outside t...

Good afternoon! As much as I would like this experiment to finally end with the detection of a problem, you assumed that all the problems are due to the fact that C1 is used for reset, but today I tried to connect the LED to port B1 and the result was the same, there are no pulses on the pin -it doe...

Good morning! I am sending you 2 programs with different LED connection. They are identical to the previous program, only the names are different.

Goodnight! There are still a lot of free terminals, if necessary, I can connect the LED to another port in the morning and see what will happen there.

Good evening! Now I have confirmed that when the LED is connected to pin C0, it stops flashing (does not light at all), there are no pulses on it. And there is our familiar signal on the Tx output.The previous program file is the same, only there the LED is connected to pin C1.

Good evening! Now in the program I connected the LED to pin C1, the signals on the Tx pin are the same as yours, and for some reason there is a pulse on pin C1 of a very long duration, but the LED is already on, but not for 1 second, but for a long time. The transfer rate is 9600.Unfortunately, it i...

Good evening! My program is the same as you described. Now I'll try to move the LED to other points and see what kind of signal it will be.

Good evening! Now I tried to rearrange the LED to pin C5 and the Tx pin turned out to have a signal similar to yours. In the figure, yellow is the signal from the C5 output, and green is from the Tx output. It's up to your new letter!

Good evening! I have the esp-01 module disconnected from my board and nothing is connected to the Tx pin except the voltage divider (it makes 3.2-3.3 volts of 5 volts) volts. In the voltage divider, at the midpoint, I have a soldered wire and I remove the Tx signal from it. In the figure where the "...

Good afternoon! Unfortunately, the miracle did not happen. Pin C0 is still empty-it looks like a line at 500ms and 2 volts and looks like a saw at 50ms and 50 millivolts... when I connect another pin to Tx, there is still a rectangular signal. I tried to connect the output of the oscilloscope CH1 to...
