  @suremicro 在 Custom Prototype Board 中说： Yes, if you head over to https://easyeda.com/zazarltd the design is there which you can use to get your own boards made. I used JLCPCB. Haven't used JLCPCB, I've used Seeedstudio Fusion service https://www.seeedstudio.com/fusion_pcb.html a few times. They are especially good if you need several of the same board as they send 10 copies

  This camera indeed works with the M5Stack, and is indeed very easy to hook up. This post is to document what I did. Simply buy the cam at the link supplied and hook it up with the pin-socket-wires that come with the camera as follows: Then clone https://github.com/ArduCAM/ArduCAM_ESP32S_UNO and copy the ArduCAM and ESP32WebServer libraries to your Arduino/libraries directory, add the client or AP data to the example script from the github (ArduCAM_ESP32S_UNO/libraries/ArduCAM/examples/ESP32/ArduCAM_ESP32_Capture/ArduCAM_ESP32_Capture.ino). Also make sure you uncomment #define OV2640_CAM and #define OV2640_MINI_2MP in the memorysaver.h file in the Arducam library dir, run the script and a webcam webserver works. (Surf to <ip>/stream or <ip>/capture).

  @Calin Thanks! I tried PlatformIO and didn't like it, maybe I should have tried longer. But if you're making something to be this easy to use, the Arduino IDE is where the users are, so I would always create for it as the primary way for people to use it. I know the JPGs take up space in flash (but 1 byte per byte, not more than they need, right?) I'd also like to know what the space in the compiled image is used for, can you also list that? There were some weird jumps in how big the image got while I was developing.

  What exactly do you call "normal code"? Without a code sample, this community won't be able to help you... I had no problem running any ESP32 code on M5Stack, after i made the proper modifications related to GPIO assignment.

  @gabi 在 How I can run espruino / javascript on the M5 Stack? 中说： how can I make the web IDE connect to the device? You should change the Web IDE baudrate to 115200 (in the settings page)

  @vsthose Hi VSTHose, See link below - Version 0.11 https://github.com/m5stack/M5GO/tree/master/firmware/v0.11 Read the flash.sh file for the TWO memory locations to flash it to..... flash it using the ESP32 Flash Download Tool under Windows or the ESP-Tool for other OS.

  At the moment, clearing the old position then printing is the fastest way to do it http://forum.m5stack.com/topic/173/how-to-avoid-text-flicker/3 you can print to sprite if you use the eSPI library and that'll gain you a few ns on the chip but I think the bottleneck is the SPI protocol, that's what Bodner was saying. You can wrap the clear and print in a function which will make your code as concise as using an object.

  @m5dude Thanks! Sorry about comments absence in code - they was on local language, and dropped automatically when downloading. Code optimisations was only on chess engine, other parts made more rudely.
