Good evening! I will be able to get in touch on 9.05 after 16 hours.

Good afternoon! Yes, you understood me correctly. Several controllers receive data from sensors and send it to the controller, which, depending on the program, performs certain actions. As for the current project, I haven't put everything I need into a diagram yet, while I'm working on it.

Good evening! I found a small circuit on the network-a bidirectional logic level converter, but I did not use it, I will try it in the simulator, but the voltage divider looks simpler and more accessible... And as for connecting several controllers via uart, I was interested because there was someho...

Good afternoon! Now, apparently, I need to connect each esp-01 module to my board with a controller and an lcd 1602 indicator? The power supply should be 3.3 volts, and the outputs of the Rx controller should be connected to the Tx output of the ESP-01 module and the Tx output of the controller to t...

Good evening! Thank you chipfryer27 for your mentorship and patience in finding the right solution to technical problems. I have reprogrammed the second module and on Monday after 16:00, if you have the opportunity, strength, patience and inspiration, we will continue to solve the problem of data tr...

Good evening, Abhi! Happy Holidays to you too! Thank you for taking a moment and writing to me! Yes, I am very grateful to my mentor Chipfryer27, thanks to him I received such knowledge and experience that you can’t get anywhere or from anyone. You talked about patience, it’s more likely not for me,...

Good afternoon Happy holiday! Today everything worked out on the first try. It is necessary for the programmers of the flovcode program to write more detailed instructions for these manipulations with the ESP 8266 module, otherwise without a glass or two you will not understand this witchcraft. The ...

Good morning! Today I dreamed that I was untying a knot. Maybe sleep and your advice will help, but first I would like to clarify: 1) do you write that the uart pins could change after the options that we have already tried, in other words, can you try connecting RX-RX and TX-TX? 2) you write that y...

Good evening! I did that screenshot with the old version of the program after paragraph 5 of your instructions.

Good evening! Yes, of course, in the older version.

Good evening! additional screenshots.

Good evening! Unfortunately, there are no changes for the better, but it turned out to erase the old device IDs (those inscriptions in the windows) and get new ones, it was possible to program again. But when checking the terminal program, nothing happened. I did it 2 times, once exactly according t...

Good evening! Well, not everything is so clear here. There may be anything in an unknown technology and board that makes it all not work. Of course, it would be great if it were possible to check such modules as approximately the correct connection of the atmega8 harness when you connect the LED and...

Good evening! Yes of course. After programming, I press stop, close the program by clicking on the cross in the upper right corner, then take out and insert the usb-ttl module into the usb connector again, turn on the terminal program and check the passage of the command. Even if I had turned off th...

Good evening! I have now checked your version about the uncheck SpiAutoSet setting-it worked, stopped jumping from QIO to DIO at the beginning of programming. But when passing commands through the terminal program, nothing has changed. There is no response to the "AT" command. The attached files con...

Good evening! Yes, I'm going to try to check your version of the SpiAutoSet flags now. Before checking the passage of the command in the terminal program, I exited the programming program and took out and put back the usb-ttl adapter with the module (for the purity of the experiment).

Good afternoon! I did as you asked. View the log file in the attached text document. But I want to note that the situation with the QIO regime has repeated itself. After pressing the start button, it jumps to DIO itself. And I immediately rearrange it manually in QIO.

Good afternoon! I also forgot to attach a screenshot of the program logs, where you can see which files I selected and to which address I was going to send.

Good afternoon! Unfortunately, the module is still silent and does not respond to commands after it has been reprogrammed.(changed addresses). The results are in the screenshots.

Good afternoon! Happy Spring and Labor Day! Thanks for the tip!. I'll check it out soon. From the outside it looks like the transfer of secret magic spells!

Good evening! I also noticed that when you start programming, you press the start button, the SPI MOD jumps from QIO mode to DIO mode itself. When I tried to reprogram it 3 times, as soon as it switched, I turned it on to QIO mode myself, programming also passed and the terminal program still does n...

Good evening! It was possible to find the reason why it was not possible to program or receive answers in the terminal program-it connected the RX and TX pins incorrectly. It was possible to reprogram, but it writes in the log that 99% was completed, not 100%. But after connecting to the terminal pr...

Good evening! I congratulate you and all those present on the upcoming holidays! Unfortunately, my happy news ended there. I stopped and am still sorting out 1 point. After connecting the wires and buttons, it is not possible to receive a response through the terminal program after sending the AT co...

Good evening! I think I found the reason why it doesn't work for me. I have a computer under the table and in order not to bend over, I began to use a usb extension cable and when I insert the usb-ttl adapter, it does not connect and the port in the "terminal" program is not correctly detected. And ...

Good morning! Thank you very much for your explanation! You see, I correctly noticed that the program does not receive information from the chip, and you explained the reason. There is no connection. I cannot now (after I have soldered the wires and buttons for programming) send commands AT and rece...
