I use M5Stack Core2 for AWS.
For UIFlow-Desktop-IDE. It works well.
For Arduino IDE. It occurs an error as below.
exec: "cmd": executable file not found in %PATH%
Error compiling for board M5Stack-Core2.
Could you suggest me to solve this error?
Thank you
I would like to use some servos based on the object detection coordinates coming from jetson nano through USB.
Somehow coordinates are being updated later and later as the time passes.
I have added the simple test code.( image url)
Re: Screen orientation on UI flow
I am going to set the screen rotation and leave it in portrait orientation. Is there a way to have the image of the Unit in UIFlow rotate to match this?
When turning the M5StickC off, and running the "FactoryTest" sketch, the screen will start flashing colors.
I believe this is due to the 'ColorBar()' function being called in that sketch, but I can't seem to figure out how it's happening. Does anyone know?
I would like to have some function that displays a "Turning off now" screen when shutting down the M5StickC
Danke für Deinen Vorschlag, werde ich mal probieren.
Ich habe es gestern doch noch mit dem PIR versucht, da dieser nur beim Auschalten eine Verzögerung von 2 Sekunden hat. Wenn der PIR auf "0" ist und er eine Bewegung erkennt, so reagiert er in meinen ersten Tests unverzögert.
Bei der Programmierung meiner Zeitmessung in Kombination mit dem PIR, reagiert dieser aber leider dennoch verzögert beim starten des Timers. Hat jemand eine Idee weshalb das so ist? Anbei ein Bild Tests:
Re: Faces stock firmware tft repl source?
I only just purchased an M5Stack Faces kit this year, with the sole desire to build a firmware based on this feature (As it is shown or mentioned in all videos relating to the faces kit)). Is the engineer that wrote this no longer contactable?
It seems you have just moved onto other products and abandoned something that had promise. It feels like you have swept the whole faces kit under the rug.
Also why is the speaker and amp so bad? all firmware produces horrible noise
@staberas
This code was very helpful. Thanks!
I tried adding temperature as well:
tmp = i2c.readfrom_mem(MPU6886_ADDRESS, MPU6886_TEMP_OUT_H, 2)
temp = (tmp[0]<<8|tmp[1])
temp = (float(temp) / 326.8) + 25.0;
I'm getting temps of 40.5C (105F). Am I doing something wrong or is this temperature the CPU temp?
Thanks,
/Chris
@m5stack thnx, I solved this problem - indeed I had to load board definitions
Also this YT-video 'M5Paper Seasons Greetings Display' was helpful: https://youtu.be/Tjz4fGRn8fo
Use :
void GT911::updateB() // as update but modify by Bricox ...
{
r814E.reads = read(0x814E); // "read struct" AND these 5 explicite bits fields
if(r814E.status)
{
if(r814E.touchPts != 0)
{
_is_finger_up = false;
_num = r814E.touchPts; // "_num" could be definitively replaced by "r814E.touchPts"
uint8_t data[num * 8];
read(0x8150, data, _num * 8); // read block of all fingers , up to 5*8 bytes
for(int j = 0; j < _num; j++) // for each finger
{
uint8_t *buf = data + j * 8;// address base of each finger
Sorry, comments that were aligned, in my notepad++ by multiple Tabs, are no longer aligned in the snippets viewer
When you install UIFlow and finish setting up the wifi, the API key will be displayed on the screen along with the mode and the network you have connected the device to.
As mentioned in the other thread, the missing step is transferring the canvas framebuffer to the EPD.
If your loop function is changed as below, it works as you expect.
void loop() {
for (int i=1; i<7; i++)
{
canvas1.drawString(testString[i],20,20);
/* m5epd_err_t UpdateArea(uint16_t x, uint16_t y, uint16_t w, uint16_t h, m5epd_update_mode_t mode); */
M5.EPD.WriteFullGram4bpp((uint8_t*)canvas1.frameBuffer());
M5.EPD.UpdateArea(0,0,100,100,UPDATE_MODE_GL16);
delay(1000);
}
}

@world101 said in M5Paper and API Key:
@ajb2k3 Actually, most of the time when I flash new firmware with M5Burner, it does assign a new API key to my device. Maybe that is because I always erase the flash before burning the firmware. I just tried it and it gave me a new API key.
@k33g give it a try. The Erase button is in the upper right corner of M5Burner. Then burn the latest M5Paper firmware.
I thought i was supposed to but for me, lately, it looked to always generate the same api.
Hi @fonix232
thank you for the clarification. Yes, being able to wake up the system from shutdown mode via touch would be nice (like it is already possible using an RTC timer or alarm).
Thanks

Hi guys
I've found that the SD card only seems to be read when it already is inserted when M5Paper is booted / reseted. Or in other words, if M5Paper already is running when I insert the SD card it is not read and going to the Factory Test Test screen returns an SD card failed. On the other hand when the SD card has been recognised and I remove it and then go to the Factory Test Test screen the SD card still passes the test.
Which leads me to my question. In the M5Paper schematic the SD card detect line is connected to GPIO34 and I already verified that reading GPIO34 actually reflects whether an SD card has been inserted or not. Has anyone already tried to use this information?
Thanks
Felix
@world101 Thanks for your reply. For the project I have in mind, I just only need beeps, but if I'm going to hack around, I'll try to attach a speaker since it would allow me to do many other things. For programming I'd go with Arduino.

Thanks Lukas, The problem was loading the font from the internal file system.
After delete all these, and place Serial.begin in the right orde loading of the fonts was no problem. Even my DSEG7Classic-Regular.ttf was loaded correct, and display correct. Converted it with the python file ttf2bin.py was also a succes in use.
One question remains. The command "createRender(168, 256)" is used for drawing bigger text, but are there limitations?
In my case when I put a larger value as 168 the screen still blanks, notting happens, but no error message shows up. The documentation is a bit fuzzy. Please can you explane this command.
