There are several examples that espressif provides if I'm not mistaken.

We do not use TPL5110. We will soon start fundraising on CS, from there you can buy the ELPMs: www.crowdsupply.com/objex/objex-link-s3lw - I suggest you sign up for the fundraiser with your email to stay updated.

@@SalvatoreRaccardi great! is is programmable with Arduino IDE?

@@ThomasHaberkorn yes sure, arduino ide, vscode platformio, micropython etc..

Custom firmware FreeRTOS ESP-IDF (No Linux)

Yes ESP-IDF, I honestly have not measured the startup time accurately, I can tell you that the microcontroller is very responsive.

In the ESP32-P4 dk docs you can find the id model of the display.

The header pins RST_LCD, PWM, 5V, GND have been connected? Have you made sure the devkit is turned on correctly? I recommend you follow the documentation: docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/esp32-p4-function-ev-board/user_guide.html

@@SalvatoreRaccardi thank you for this Quick answer, i think i did all of that but i will investigate again

@@riendeplus1923 I just now followed his instructions when I unboxed my kit, and it started up immediately. I think you either have mis-wired yours, or maybe even your unit is defective. Re-check your wiring and try again?

Ok, so, i think a DuPont cable was guilty in this story ... :)

It is coded in C, it is an embedded system.

I see now. I thought it is a tablet😊​@@SalvatoreRaccardi

Are you kidding me? 😂

@@SalvatoreRaccardi 😁, really, it's a good idea adding usb power delivery to the system. Cheers.

I had honestly thought of developing a demo to control twitch chat and other things. Do you think it could be interesting. Maybe leave the code opensource on github.

@@SalvatoreRaccardi Do you think you could write the drivers required to make this P4 screen work with esphome? I think there would be a big audience for such a controller.

@@JamesTenniswood I think there is already someone who is doing it. I could work on it too.

For smarthome is perfect

Grazie!

I've demonstrated the potential of the ESP32-P4 by integrating it into the projects I've developed. Simply showing the ESP32-P4 without real-world demos wouldn't have conveyed its true capabilities or possible applications. Plus, showcasing the projects I've worked on is part of the goal of the video, and I see no problem with that.

Yep, the ESP32-P4 will significantly simplify the development of a wide range of projects.

Thank you very much!

Thank you so much for your comment and for the continuous support. I agree with you, the lack of an embedded Wi-Fi/BLE/... transceiver in the ESP32-P4 is a bit of a drawback, especially for smart home projects where connectivity is key. However, I think Espressif focused on performance and flexibility, allowing developers to combine different modules like the ESP32-C3 or C6/C5/H2.

@@SalvatoreRaccardi i still think they will release some kind of upgrade soon.

Mistake? not really. With the radio sharing the chip with fast dual core MCU would likely disturb it quite a lot. The two chip solution is likely to give better wifi and processing performance.

Good point.

Thank you so much for your support! You will be able to buy every single accessory, including the 3D case. We are working on a final version for fundraising.

​@@SalvatoreRaccardi That's great, I'm looking forward to it. Also, I just put up a note on the esp32 reddit forum to help spread the word. Good luck!

In the coming weeks, we will launch a crowdfunding campaign on CrowdSupply. For now, we are focusing on promoting the product.

ESP32 devkit

To be more precise without a standard AA/AAA/Coincell type battery.

@SalvatoreRaccardi these new chips I've seen using very low power. Are any of the less ordinary energy harvesting solutions like piezo electric disc's vibrating able to power this chip to send readings?

@@crouchingchicken007 Tests should be done with piezo electric, consider that the energy harvester should also be changed. Do you have any applications that use piezo electrics?

@SalvatoreRaccardi thanks for your response. Currently looking at vibrations and heavy forces being exerted onto the plates but not to extent of bending them

It can be done, would you just like to have a usb-c like interface like the classic devkits or would you like more? Would you keep the ESP32-P4 + ESP32-C6 combination?

@@SalvatoreRaccardi Don't really care as long as its small, mostly interested in the camera & display interface. And how hard it is to implement different displays for this. I would have a project that im now building using raspberry pi that uses a 2.9" 1440x1440 display and the camera interface. But i dont really like linux, MCU would be so much faster to boot up. There already seems to be one quite compact P4 module, WT01P4C6-S1.

Thank you!

Theoretically it is so

Have you tried to see if other people online have experienced a similar problem?

@@SalvatoreRaccardi Thank you very much for your response. Yes, I have asked on several forums, but so far they have not been able to give me an answer.

We are not sure if the problem is a configuration, library or PCB communication system issue.

what antenna are you using?

@@SalvatoreRaccardi I'm using an ESP32-C3-Mini-1

Yes, it could be useful for many IIoT apllications.

Learn any other info? Would this be a good choice for building a gauge cluster? I want to run a 4" round touchscreen for an offroad vehicle.

I think it will be mainly targeted for HMI setups. Maybe also portable setups like barcode scanner applications for delivery jobs or local UI control for applications like Home Wizard. As soon as I get my hands on one of those dev boards, I will try to add support for it in ESPEasy, but that does require quite a big overhaul as I need to get rid of WiFi code and currently it will not build without WiFi code.

The chip itself is only some few dollars. Power consumption is unknown to me, but given the other chips running without wifi is rather low power it can't be THAT bad. The screen itself is likely to dominate it all! Camera with some smarts in (camera to ethernet/usb) including video overlays and video encoder, touchscreens with slow link toward the rest of the system, many options.

After the fundraiser, all schematics will be open source.

Hi! I changed the mosfet only because of availability. I added the LDO to the BME680 because I wanted to do some additional tests.

@@SalvatoreRaccardi thanks you for the answer! Did you ever get to incorporate the BME and used the door sensor as a environmental sensor as welll?

Power Delivery PPS 3.0, LoRa, Extreme Low Power 1-100nA

The 3 main differences

@@SalvatoreRaccardi cool! However, it uses an esp chip so how is your third argument of extreme low power even valid?

@@bobby9568 custom power latch with extreme low power RTC

@@SalvatoreRaccardi meaning low power is only true at certain external events

Thank you!
