Hi,
Here I wont to show the status of my little project. Have take the example of David Bird (4.2" weather display for e-paper) and rebuild this for the M5Paper. Divide the whole project in 3 screens, with the switch on top I can choose the screen.
As you can see the project is still in progress. One of the things I can't fix is to display the time ( right upper corner) without updating the whole screen.
Has someone tried to make a kind of a clock ?

Will keep you informed about the project.

Cheers

Jan

Are you thinking using an API Call like calling open weather map? I use OWM api to get the weather forecast on my M5Stack. Use alo a kind of marque to present the data 4 times in a hour, an when pushing the B-button. Make also graphs, when pushing the A-button.

Cheers,
Jan

@zamzam
Do you have tried to slow down the upload speed. Had the same with other brands, after reducing the upload speed it works.
Succes,

Hello,

Load the Arduino envoirment on a brand new MacBook Pro.
Try to compile The Core2 and the M5Stack fire.

Now I get the message : No module named serial.
On the system is the latest version of python installed.

What to do?

File "/Users/jankromhout/Library/Arduino15/packages/m5stack/tools/esptool_py/3.0.0/esptool.py", line 39, in <module>
import serial
ImportError: No module named serial
exit status 1
Fout bij het compileren voor board M5Stack-FIRE

Found the problem. After deleting an old sdfat and installing a new one it was working perfect on my Core2.

Is it possible to read/write blocks of 512 bytes direct to the sd card?
This without using the M5Stack filesystem.
I know with the SDFat.h library it is possible, there are commands for readBlock(block,buffer) and writeBlock(block, buffer), and buffer is defined as
byte buffer[512].
But I get not compiled this library under my Core2.
Appreciatie any help with this.

Jan
