Hi,
it's been a while, but meanwhile zephyr supports some M5Stack boards (e.g. Core2: https://docs.zephyrproject.org/latest/boards/xtensa/m5stack_core2/doc/index.html).

In combination with LVGL this offers wide range of opportunities.

the board in your link seems to have PSRAM but in the code the selected model has "No PSRAM".

Hi @osioli,

You can upload to the core first this code (I'm using the Gray core):

#include <M5Stack.h>

HardwareSerial GPS(2);

void setup() {
GPS.begin(9600);
Serial.begin(115200);
}

void loop() {
for (;;) {
if (GPS.available() > 0)
Serial.write(GPS.read());
if (Serial.available() > 0)
GPS.write(Serial.read());
}
}

In u-center set the baud rate to 115200. Go to View-Messages View (F9), expand UBX-CFG-MSG and check UART1.

In my case the satellites detection only works outdoors.

Thanks for the replies

@NotInTheMafia The touchscreen uses i2C, so does the AXP192. What could be happening is an i2C bus error, due to the address of the touchscreen not being present, and no more data being sent to the AXP192, resulting in no power past that point.

Hi Dieter,

Do you have any new information about this topic. I‘m struggeling with the same problem, that i can‘t flash from ESPHome to my Atom Lite ESP32 IoT DevKit (Esp32 pico).

You can find the connection instructions here: https://docs.m5stack.com/en/core/stamp_pico?id=description&ref=pfpqkvphmgr

@iamliubo hi, thanks for the reply.

I managed to do the example from what you gave and I got the results as it is. but, after several checking, I received bytes from the uart. Then, I need to convert to hex. the method i used is:

hexVal = hex(int.from_bytes(serData, "big")) label14.set_text(str(hexVal)) //to show the hexVal to the label

I got the idea from the example you gave and THANK YOU so much for that =)

Hi @Exie, have you managed to talk to the Zigbee unit through UART or managed to comprehend the example code given by M5Stack?

Regards,
Ameer

@starlog In Arduino IDE it is easy to do:
upload any sketch and the check the upload stream (the bottom of the IDE) by scrolling back up to the start.

Sketch uses 243709 bytes (7%) of program storage space. Maximum is 3145728 bytes. Global variables use 19348 bytes (5%) of dynamic memory, leaving 308332 bytes for local variables. Maximum is 327680 bytes. esptool.py v4.5.1 Serial port /dev/cu.usbmodem101 Connecting... Chip is ESP32-S3 (revision v0.1) Features: WiFi, BLE Crystal is 40MHz MAC: 68:b6:b3:22:4c:6c Uploading stub... Running stub... Stub running... Changing baud rate to 921600 etc.

Hello @StarLog

you can find it here.

Note: There is some confusion about the filename. LED_Display.h vs. LED_DisPlay.h.

Under Windows it doesn't matter, but under MacOS or Linux it does.

Thanks
Felix

If I were you, I would seek the advice https://tech-stack.com/services/consulting-service of experts in custom software development, who would be able to competently answer your question

Only the built in ui builder

@nick-n17 First you have to log-in with that account you are using, second go to user custom, third click publish and fill all the information needed and then click upload, fourth click publish.

@dclaar I have no problem with the Stamp-PICO running on the 3.3V power from the programmer.
And the StampS3 running on USB 5V actually outputs out 3.3V at the RGB output...
So, YES!

i downloaded and installed the sources into the specified folder. and also checked the path. but still can not be found..

Now I tried to do it extrem more on a basic level with the latest available versions of everything with Arduino

#include <Arduino.h> #include <M5Atom.h> void setup() { M5.begin(true, false, true); M5.dis.begin(); } void loop() { M5.update(); M5.dis.drawpix(0, 0xFF0000); delay(500); }

I assumed that this simply meant a permanent "RED", but it results in a random play of colours.

I'm having the same issue - did you find a workaround?
