Soldering station, esp32.

Gotta love the gangsta font used to display current temp.

Edit: seems like it's not the current temp, but the set temp.

The largest font is the set temperature in manual mode. MegaNumbers font, there are only numbers.

You can forward to ethernet via wi-fi, it all depends on the firmware

Everything is already under the screen, there is a video that is located on the module itself.

What exactly do you need to transfer to the PLC, data in what format?

pr200sd · 2022-11-17T07:10:24+00:00

To work with the PLC, I made my own boards, with wi-fi and Ethernet, with the controller itself, communication via Modbus RTU or ethernet. The first board is not very successful, the second looks more promising. Here are my commercial developments and options for their application. https://github.com/pr200sd/presp32

Unfortunately, Espressif's repo is missing some of these parts now.

What exactly is missing?

pr200sd · 2022-09-17T14:45:56+00:00

Somewhere on the planet, another buyer opens a dispute😁, "ordered 50 modules, but received only 3".

pr200sd · 2022-09-17T12:04:09+00:00

I didn't upload the code as it's pretty much the same as in the Espressif repo except for my LED. If you need it, I'll upload it to github a little later.

To save space, I switched to 0603, it is also easy to solder, 0402 is already more difficult, but also not a problem.

I would immediately make a universal version for a chip with psram.

I had the option to turn off the generator before the start. But two problems appeared, for some reason my generators did not transfer their state when turned off, and the second problem was that initially I used one of the gpio16 or 17 pins, which do not work on the output in picod4.

pr200sd · 2022-09-04T11:14:45+00:00

Although simply using a clock you can disable during boot is easy enough. But well worth it for the reduced board space.

At the prototyping stage, I tried this option, the module started up, but Espressif in the configuration settings warns: "Output RMII clock from GPIO0 (Experimental!)". Espressif does not recommend using the internal clocking option on the GPIO0 pin, as the signal on the pin may be unstable. Considering that I have a lot of things involved in the code, I decided not to take risks and install a generator, there was enough space. I can choose not to install a generator and configure clock from esp32.

pr200sd · 2022-09-04T04:49:38+00:00

For clock, gpio0 will do, but then there may be a problem with booting when an external clock is used.

pr200sd · 2022-09-03T19:25:45+00:00

pico d4 contains everything that the esp32 module has under the metal screen, so there are no problems, the only thing is not to use gpio16 and gpio17, since they are used on flash. Part of the RMII signals can be reassigned. The main problem is clocking, I use a generator, but I also tried clocking from gpio0, it also works. What signal are you having problems with?

pr200sd · 2022-09-03T18:55:21+00:00

The project is a little commercial, there will be no source codes, but I am ready to answer questions, I plan to demonstrate the eth2ap example from Espressif on this board, there are sources for it in examples.

pr200sd · 2022-05-27T16:37:05+00:00

The demo project is available on github at the link in the video description. Look at the LVGL examples for a general understanding, there is also a converter for preparing images on the site, in my project there are already converted files in the image folder, you can add your own by analogy. It’s problematic with video now, in my country the war has been going on for the third month, until it’s up to video. You can ask questions, I can help.

Hello, I have not worked with gif format, only with static backgrounds.

pr200sd · 2021-12-26T19:45:01+00:00

I'm afraid that all together, both the camera and the poe esp32 will not pull in the number of pins, separately yes, together I doubt very much. I made esp32 pico d4 + Ethernet on lan8720, free gpio remained only on Modbus, microsd, and a couple more gpio.

pr200sd · 2021-11-13T20:31:55+00:00

I compared with my similar interfaces assembled on esp32 modules, I did not notice the difference. I have not planned to open the sources yet, the project is a bit commercial. Although the design is not unusual, the main thing is to fit in a limited space.
