    Hi, I have several ATOM PICO Lite (grey) modules that when I connect them with an USB cable to my laptop, a COM port is shown in my WIN11 device list under Ports (COM & LTP).When I connect to the device in ESPHome, I can see the com port in the pop-up box and when I select the COM port I can establish a connection and install software on the PICO lite. Problem: I recently bought several new ATOM ECHO S3R. When I plug these to my USB port, I dont see a COM port appearing in my Win11 Device list. As a result I can also not connect from ESPHome to the device. I tried to install drivers from this site https://ftdichip.com/drivers/vcp-drivers/ but that did not help. Any tips what I can do to communicate with my new ATOM S3R modules? Thanks for tips! Regards, Jules

    @俺がガンダムだ said in LVGL performance problem: I applied LVGL on stickc-plus2，with TFT_eSPI's st7789v2 driver.But the refreshing rate is very low (while doing "load screen anim").I know stickc had good performance on drawing screen (by watching the video of M5stick T-Lite Thermal tutorial). And the LVGL also has a good performance through Dial-ESP32-S3 and Din-Meter demonstration video. So what is the reason of such low performance. Cound it be the TFT_eSPI library? I’ve seen similar issues on the StickC-Plus2. It could be due to TFT_eSPI settings, try increasing the SPI frequency or enabling DMA. Also, check your LVGL buffer config; full buffering helps with performance.

    Hello! I am new to the community here and have been finally been playing around with my m5stack core2 with rust. My project consists in a simple voice recorder which does the following: After pressing a button, start recording from the microphone to the SD card Show a timer of the elapsed time Once the user presses the stop button, stop the recording Then upload the recording to a server I got every bit working independently but the problem is getting them to coexist. The reason I am posting here now is that I am completely unable to figure out how to get the display to work (e.g. update the elapsed timer and/or react to user button presses) while also having an active microphone recorder which writes a wav file directly to the SD card. I found quite a bit of conversations about it being a limitation of how the lines are shared between the display and the sd card. Some even suggested the existence of some workaround to get them to work but I couldn't get any to work with rust/esp-idf. Has anyone here managed to get this to work? I would be pretty surprised if 2 such core features (the screen and the SD card) were really not possible to coexist, as that would destroy almost all my project ideas for the m5stack.

    @simondid have you even tried to look it up yourself? Google's first hit is literally this thread from April, including a full ESPHome config. ESPHome also has a draft PR for including EPDiy as a generic display platform, and EPDiy itself has a PaperS3 pull request, which will allow the BMI270 component from the above thread to work (currently EPDiy tries to import some legacy code that breaks I2C, as patrick3399 used a custom fork of EPDiy that isn't exactly up to date).

    @Jomac said in Tab 5 screen flicker after firmware update: @sapphire said in Tab 5 screen flicker after firmware update: @Jomac If you watch the video, I have this little defect that doesn't happen often (a flashing). The link doesn't work for me Well I flashed the firmware several times and also flashed a couple of apps on M5Burner and nothing made any difference, everything just flickered so I switched off and left it for the night, next morning I was going to video the issue and when I switched on my Tab 5 again, the fault had cleared.

    Okay, posting to help others as I did find the solution to this. As the error message states, the binary has to be suid root. You can get it going by typing: sudo chmod 4755 bin/chrome-sandbox From wherever you installed M5Burner. This, and adding the current user to the dialout group, should really be part of the installation instructions. I can't see how anyone on Linux would avoid doing both of these steps. Now I if I can figure out why the Tab5 is bootlooping i'll be up and running...

    I'm curious—will the iOS version of EzData support the same modules and data types as the M5Stack Core devices? Also wondering if there's going to be integration with iCloud or local storage for exporting logs. I’ve been exploring some related iOS app development workflows, such as those outlined at Idea Maker, and wondering how closely EzData aligns with those practices. Looking forward to seeing how it develops.

    @Jomac said in Cardputer Driver Issues: @robski said in Cardputer Driver Issues: do you use m5burner? if so what com port it shows there when you connect cardputer? also what com port it is showing when cardputers on/off switch is in off and then you press and hold BOOT btn and then connect usb? It depends on how it feels, sometimes it will connect on Com 4 and other times on Com 9??? thing is that comport you see with just connecting cardputer to usb is one of two available second comport (needed for programming) is visible when on dead device you press and hold boot button G0 and then connect to usb

    For the M5Stack Core2, Grove Port A uses I2C on GPIO 21 (SDA) and GPIO 22 (SCL). However, when using a Pb.HUB, you're communicating with the hub over I2C, and each connected unit (like relays or RGB) is addressed virtually via the hub. Since openHASP doesn't natively support Pb.HUB devices, you can’t directly control GPIOs through it. Instead, you’d need custom firmware or integrate via ESPHome or Arduino to bridge Pb.HUB control with openHASP. TL;DR: GPIO 21/22 for I2C, but control of devices via Pb.HUB needs extra handling outside openHASP.

    @teastain Here the answer: M5.Lcd.print("Temp:"); M5.Lcd.print(t,0); M5.Lcd.print(char(247));M5.Lcd.println("C"); I guess you have found it meanwhile, but perhaps it is useful for others.

    Hey @roanevic, just jumping in here, I’ve tried that same setup recently. The example code Kuriko linked is a good starting point: https://github.com/m5stack/M5-RoverC/tree/master/examples/RoverC_JoyC_Remote It’s designed for StickC, StickC Plus, and the StickC Plus2, so it should work with your hardware. Just make sure you have all the necessary libraries installed (like M5StickCPlus2, RoverC, and JoyC) in the Arduino IDE. Let me know if you hit any snags setting it up.

    Hello @daniel-edge456 in UIFlow2 v2.2.6 using touch blocks for M5Paper and then look into the Python tab I get the following code to get touch coordinates: if (M5.Touch.getCount()) > 0: x = M5.Touch.getX() y = M5.Touch.getY() doing the same with power blocks I get: Power.deepSleep(1000, True) to put M5Paper into deep sleep. Thanks Felix
