    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.

    To whoever faces same problem - I found solution for win10. Problem is, UIFlow offline installs wrong/incorrect drivers, but as they are signed by Microsoft, Windows treats them as correct ones. UIFlow works fine, but VS won't connect to M5Stack properly. Boot into safe mode, plug in M5Stack and find COM (Silicon labs) device. Right click and remove it, what is important, press checkbox with "Remove associated with device drivers" which appears only in safe mode for me. Now disconnect USB, download latest drivers from M5stack.com and install them normally. This solved issue for me

    Hi @Thrasher, did you take a look at those libraries? you still didn't mention what it is that you want to do. There is also the framebuf library that may help, search framebuf.py on github

    @jerry_fuyi I suggest you to add some random logic blocks and then see it in python code - will be much easier to understand mechanics. Ofcourse, coding hardware is useless without event triggers most of time

    Hi, you can find the datasheet here. It is in Chinese but Google translate does a pretty decent job so we can understand almost everything. You can also have a look a register 36h where you can modify long/short press times. Be careful, this button is used to power-on/off the device
