NO response?

Do we have any way to lock/unlock a region of esp flash memory from writing function?

- What hardware are you using specifically? What's the power supply like? What specific version of Wroom are you using, with what amount of flash? . The figure below show the ESPWROM version, we are using. The power supply is 3.3V. esp32.jpg - What environment is the product used in? Anything like h...

Dear ESP32 supporter, Our company is making a product using ESP32. We released nearly 1000 products to our customers using ESP32-WROOM. At the first stage, we made firmware for ESP32-WROOM. We downloaded our firmware using ESP DOWNLOAD TOOL. And it worked very well. We did test with the full system ...

Dear ESP supporters, I'm working with ESP32-D2WD. I used several GPIO pins (such as GPIO4) as a SoftwareSerial RX port. It worked very well. I would like to know why the GPIO34, GPIO35 cannot be used as SoftwareSerial RX ports? Here is the symptom of using GPIO34 as UART RX. It read the first byte w...

Thank you for your helps!

We will select another pin instead of using GPIO16.

Dear ESP supporters, Our company is making a product using ESP32. At the first stage, we used the ESP32-WROOM for the demo version. We used the GPIO16 as a UART RX for reading data from the dust sensor PMS7003. And the demo worked very well. At the second stage, we used the ESP32-D2WD for the real p...

Hi Angus, Firstly, thank you very much for your quick response. Your answer gave a big help to me. I really want to you LCD with these pins because other pins are fully busy in my design. Therefore, I have a small question about this topic. Is there any difference if I use ESP32-D2 or ESP32-D4-PICO?...

At the first stage, I connected my LCD to ESP32 with GPIO25, GPU26, GPIO27, GPIO18, and GPIO23 as in the below figure. And it worked very well. isssue1.jpg Unfortunately, this group of GPIO (25, 26, 27, 28, 23) are now busy with other connection. Then I tried to connect my LCD with group GPIO (11, 1...
