Hello @Gorilla thank you for reporting back. I am glad you figured it out. And yes, there were some recent changes to the EXTIO2 library regarding I2C so getting the latest is key. Thanks Felix

Hello @Marelli7 you are welcome. I sounds like you are having fun. And thanks for reporting back. I am glad to hear you got it working to your liking. Thanks Felix

@fosouza Thanks! It took some quick-clicking, but I got the 2.0.5 installed.

Hi, You wrote: Once the M5Stack is powered off, only the CAN information can no longer be read. So the solution is easy: Power ON the M5 device! Or do you mean OTHER devices on the same CAN are not able to read data WHILE M5 is OFF? In this case it might be possible that the CAN transceiver in the Commu is still powered (check that!) but miss the input signal. According to the datasheet of the CAN driver chip the bus output is dominant while TXD and S pins are LOW. This blocks the communication of other devices. It may help to solder the pin 8 of the transceiver to +3.3V instead of GND to enable silent mode (switch it to Rx only) or make sure the commu is not powered. The bus driver is then going to float (Off Mode) and should not block the communication anymore.

JPG has several Cilor Mode. Use as JPG RGB MODE For example, you can do it with GIMP.

@mickey95 dude?

Thank you for the update.

Hello felix, seems to work, thanks. Will see how long m5paper could work without charge. Fred

Hi @felmue and thanks for the help. I changed GPIO and it works now. Strange as input port 2 worked when the temperature sensor were implemented separably. However I have spend enough time trying to make it work. So I will not conplain now that it is working. Thanks again

@felmue Thank you so much Felix, you've helped me again.

@ajb2k3 To clarify, I think you're implying that some of the other APIs are available to me on M5Paper, but some aren't - is that correct? Yes, correct. Is there any way to tell which ones can and which can't? Is it API by API, or is it more granular - certain functions documented under other APIs are available? For example, are the functions under https://docs.m5stack.com/en/api/core/power available - lightSleep, deepSleep etc? Thanks again for all the help.

Thanks Felix and @ajb2k3. I've found the root of my problem, which is that I was using a different update mode (DU4) in the loop than in the setup (GC16). From this I infer that there are least two buffers in a canvas (one for graphics, one for text); since when I pushed the canvas shifted to a different position, using DU4, it placed the text in a shifted position, but didn't update the graphic. Is that correct, and are there more than two buffers?

Thank you both Felix and @silentmonkey. I'm navigating the M5 docs, but as I've whinged elsewhere, although they give function signatures (not complete I think, e.g. I've seen examples which don't match the reference) I'm missing context. In relation to HTTP, there seem to be a lot of different Arduino libraries - copy and pasting from random examples on the internet has got me somewhere, but is there any guidance for a newbie as to the 'good' ones to go for? For example I'm currently able to fetch data from 'http:' URL, but not 'https:' - although the canvas.drawJpgUrl example function uses an 'https:' URL and that works... Thanks again for responding.

Hello @ Stoni99 The same question is: https://forum.m5stack.com/topic/4180/writing-and-re-writing-text/6

Connect the QMP6 to the hub and the hub gives it a different virtual address. Address are often set at the hardware level and can sometimes be changes by changing the solder points on the PCB of the sensor.

Unfortunately, a restart doesn't help either. maybe it's because of my older router.
