Thank you for your valuable answer. Now I can see an image from a web browser. I have more questions about this. 1. How can I set the image size (ex: .frame_size = FRAMESIZE_UXGA,//QQVGA-QXGA Do not use sizes above QVGA when not JPEG)? 2. Is it possible to send a streaming image to see it by the web...

ESP32 Camera (ESP32 Cam) Library
I have an ESP32 camera(OV2640) board.
https://www.aliexpress.com/item/3299266 ... 4c4d7c0Bk3
Is there any MicroPython library for ESP32 camera board for using " import camera"?
if not, is there any plan to make MicroPython library for the camera?

Print dot(.) problem of jupyter notebook MicroPython Kernel
I use the Jupyter notebook MicroPython Kernel for ESP32. ==> https://github.com/goatchurchprime/jupyter_micropython_kernel It works well. However, sometime Jupyter notebook MicroPython Kernel prints "." that I didn’t print, when I use ‘print()’ with "for" or "while" statement. Followings are my code...

Frequency measurement using ESP32
Hi, all. I would like to measure the frequency of an external input signal using ESP32. In the case of Arduino, pulseIn() is used to measure frequency. Therefore I tried to use similar function (machine.time_pulse_us())to measure frequency. However, the accuracy of this function is not good. Is ther...

Pin input pull-mode of ESP32 WROVER module
I am using ESP32 WROVER module. Can I set input pull-mode as follows, when I use a Pin as the input mode for ESP32 WROVER module? 1) p = Pin(Pin_number, Pin.IN) # for No Pull 2) p = Pin(Pin_number, Pin.IN, Pin.PULL_UP) 3) p = Pin(Pin_number, Pin.IN, Pin.PULL_DOWN) When I refer to ESP8266 GPIO Pin do...

How can I use Webrepl for ESP32?
WebREPL allowed me to use the Python prompt over WiFi for ESP8266.
It was very convenient.
Now, I am testing ESP32 board(ESP-WROOM-32 Development board).

What are ESP32 SPI Ports for Micropython SPI(1)?
I make bin files for ESP32 module( ESP-WROOM-32) Now I would like to test hardware SPI function using Micropython. Please let me know the Hardware SPI port in ESP32 module( ESP-WROOM-32) for Micropython code? For example. 1) SPI(1) SPI_MISO = HSPIQ(GPIO12) SPI_MOSI = HSPID(GPIO13) SPI_CLK = HSPICLK(...
