I assume that I a am not the first one to ask, but how can I select other fonts? Thanks

I have been googling around, no understandable answers found. But I am sure I am not the only one with this interest.
Could anyone explain the binary format of the sound stream used in the echo? And also nice to have : howto proces a mp3 or wav file into the required binary array to be used in the Echo?
Thanks.

A few tips who want to start with this module:
1] Remove PIN code, makes life much easier
2] Download the application notes for this module. Both the complete AT instruction set and the note on HTTP application. This document provides clear instructions how to use HTTP, GET, POST etc
3] I experienced ERROR response on SHCONF command. Googled around, saw numerous hits. It appears that switching off and on power does the trick for me. I did not see a reset AT instruction
4] I got it all working with these instructions :
Serial.println("Begin..");
//pinMode(RXD2, INPUT);
//pinMode(TXD2, OUTPUT);
//showLog("Reset Module...");
//SIM7020
//DTU.Init(&Serial1,36, 26);

@cepics said in ATOM Lite Display not display in smallHd 503:

SmallHD503 datasheet

I read that you are also struggling with this (5 inch?) display. I am facing the same issues with Waveshare 5inch display. Although I have the very strong feeling that the software on the M5AtomDisplay as shipped is different from the GitHub factory test. Have you been able to get things working?

#include <HardwareSerial.h>
HardwareSerial Comm(1);

Comm.begin(115200, SERIAL_8N1,TX_pin,RX_pin); // TX RX

Comm.print("AT+IPR=115200\r"); // Set text mode

Last command should return an OK. If not, it could be that you have mixed up TX and RX pins or a power issue.

To read the reply from the module you could use something like this :
while (millis()<wait_until)
{
while (Comm.available())
{
ccc=Comm.read();
//Serial.print(ccc);
if (k<buffer_size-1)
{
Receive_buffer[k]=ccc;
k++;
}
}
Receive_buffer[k]=NULL;
if (strstr(Receive_buffer,StopCharArray)!=NULL)
{
//Serial.println("OK found");
// SIM7600_Error=0;
Receive_buffer[k]=NULL;
return false;
}
}

Okay, Had a lot of <bad language> getting sending email working.
Than I realized that powering the module straight from the M5StickC appeared to causes glitches. I have placed a capacitor on top of the 5Volt to the module and now I am able to send emails also. For those that are interested, here is the code (with a lot of overhead no doubt, that works for me ):

Interesting question. M5Stack provides P2P LoRa example along with their documents. My suggestion is to make a proof of principle what you need. Then try the max achievable distance. Mqtt is another challenge but also many examples on GitHub.

Solved
I don't why I have been klinging on to Serial2, it got me in all kind of testing out, but the solution is to use Serial 1.

@laursena please check the version of ClosedCube.cpp and ClosedCube.h you are using. The one that is provided by M5stack is the newest.
(* In the examples of M5StickCPlus in the directory Unit/PaHub you may find these documents. *)

@paulpattyn Uh, how about use Google : https://www.instructables.com/Post-to-Google-Docs-with-Arduino/
Regards

@kuriko Thank you. I would have hoped that they also supply Arduino code.

Hi there,
I was wondering, where can I find software, for example the firmware, that I can open directly in the Arduino development software. I have found the GitHub page but I don’t see any .ino files.
Thanks.

@laursena please check the version of ClosedCube.cpp and ClosedCube.h you are using. The one that is provided by M5stack is the newest.
(* In the examples of M5StickCPlus in the directory Unit/PaHub you may find these documents. *)

SOLVED : After remeniscing abount my life, and specifically what goes wrong here, i just realised : could it be that I am using an outdated library of ClosedCube. And yes, after using the version from 4 April 2023, everything works fine now.

@felmue In Dutch : Krijg nou wat?
I put the RFID 2 module in slot 1 of the TCA 9548A module and then in channel 0 (weird because i have placed it in channel 1) i see address 0x28 of the RFID popping up.

Does this mean that channel 0 on the module is not usable?
Thanks

In follow_up , I have checked ClosedCube_TCA9548A.cpp and the selctChannel goes like this :

uint8_t ClosedCube::Wired::TCA9548A::selectChannel(uint8_t channel) {
    uint8_t result = 0xff;
    if (channel < TCA9548A_MAX_CHANNELS) {
        Wire.beginTransmission(_address);
        Wire.write(((uint8_t)1) << (channel));

        _currentChannel = channel;
        result          = Wire.endTransmission();
    }
    return result;
}

That seems to be correct if I read the documentation of the Texas Instrument module TCA9548A

I am really misunderstaning something or could it be that their is somekind of wire mixup in the module?

Btw, I also dont see a reset channel somewhere in the code.

Now i did another experiment using PCA9548AP (the newer version).
Plugging in the RFID in channel 0 gives no response.
Plugging in channel 1 : software tels me the device is in channel 0
Plugging in a second RFID in channel 2 :software tells met a I have another device in channel 1.

I tried to increase the max number of channels to 8 (assuming that channel 0 is somehow connected to channel 7 of 8). Still no response when i attach a device physically on channel 0.

This is really weird behaviour. I hope someone is at least able to reproduce this behaviour.

@cepics Have you checked whether M5UnitScroll.begin returns true? Baybe that gives a clue.
Regards

@felmue Sorry for my late response, been a bit occupied. Tried exacltly the include code with the most recent version of M5Unified (0.2.1) and M5Stack board manager (version 2.1.2). Connect the RFID 2 unit to slot 0 of the TCA9548A module (boh M5Stack products.
It only lists for each channel 0x70 wire ping value. I would have expected for channel 0 to have a response on 0x28 (native wire address of the RFID 2 module). Maybe it is because the RFID module has not been inititated yet. But I do not know where to put the init of the RFID module. Tried at different place in the code , to no avail. I hope someone has an idea of where I am going wrong here.```

Hello,
The RFID 2 unit works fine when connected directly to M5Core2.
Now, I connect the I2C hub to the M5Core 2 and connect the RFID 2 device to channel 0 of the I2C hub.
I run the following programs. I would assume that the RFID 2 device would show with address 0x28. But it does not, it only gives 0X70 which is the I2C device itself. What am i missing here?

Indeed a strange situation.
It occurs if I use TX=26 and RX=32 and also TX=22 and RX=19 to initiate the can BUS on a M5Atom
ESP32Can.CANInit(); // Init CAN Module. 初始化Can

If i dont initiate WifI I can send data through the CAN BUS. The moment I initiate WiFi, no data come through in the CAN BUS.

I will do some other trials with other devices (M5Core 2 and M5Atom S3) to check if it is a hardware problem.

I do hope to get this solved because if this problem is definite it means the Communication abilites of the CAN bus are limited.
Regards

(* Oh, important : When using WiFi i do receive CAN BUS messages , so that is weird, i really need to dive into this*)

@kuriko I use Arduino.

I am curious if this is a hardware issue or software (incompatibility between Wifi and the CAN bus protocol).

It does not work with ports 26 and 32 as well as ports 22 and 19 for communication with the CAN bus port
