Hello @inkto

just curious. How do you determine the system hangs? Care to share your program?

Thanks

Just for FYI, as of this date, the W5500 hardwire ethernet port is not well implemented in MicroPython (use wireless instead). The POE function works fine so you can use it to power your module, but communication is not working on the wired LAN.

It works fine in Arduino IDE.

Hello @derhaase

interesting question - which got me curious if this is actually doable on M5Paper or not.

Using all three ports (A, B and C) available on M5Paper gives you 6 GPIOs of which you can use port A for I2C (SDA and SCL) and port B and C for SPI (SCK, MOSI, MISO and CS).

I did a quick test with the M5Stack Ethernet module (which uses SPI as well) and I got it working alongside the display. The trick is to properly initialize the SPI peripherals. ESP32 has four of them, two are used internally and one is used for the M5Paper display. This leaves one to connect another SPI slave device.

Please note: I do not have the camera module, so I cannot test if it works with that camera as well.

Good luck!

Thanks
Felix

M5Stack support sent me this.

I was hoping that was the case. I'll just have to try it. Thank-you.

What browser are you used? this function use with Safari has some compatible issues. so maybe you could try to use chrome

Hello @jvm

open the files Ethernet.h and EthernetServer.cpp, then search for the commented out lines and replace those.

Since you are using an M5Core2 you'll also want to adapt the SPI pins as they are slightly different between M5Stack and M5Core2.

M5Stack uses:

#define SCK 18 #define MISO 19 #define MOSI 23 #define CS 26

M5Core2 uses:

#define SCK 18 #define MISO 38 #define MOSI 23 #define CS 26

Please also refer to this GPIO comparison sheet I've compiled a while ago.

Thanks
Felix

Hello @pferrac

I don't think the schematics for the piggy-back boards are publicly available. I am not even sure they are from M5Stack themselves. Maybe you get lucky and find some information from the manufacturer of the GPS chip. Regarding pinout: from the pictures I gather that there is VIN, GND, TX, RX and RST. The rest of the pins do not seem to be used.

Thanks
Felix

Having a similar issue, I've got into the web server, but the AP isn't starting, I can't even find the AP ID or even tell if it's started?

@world101 I couldn't get it to work with the Universal G code sender. It was like it could tell it was there, but it didn't seem to communicate. I think there's a lot to do with it all being ESP32 based or that you're going through a computer through the esp32 to the grbl module...I'm not sure. there is a I've not gotten any further along with it. I pretty much put it to the side and had hoped to come back to it. I think you could read line by line from a file on the SD card and write it to the GRBL module. So on my Shapeoko cnc router I can use the command $$ to see the parameters and settings and change many variables to setup a machine as you need it set. I do not see how you can do that with this device. Maybe in the arduino environment you can you the serial monitor. I was really disappointed that there is no documentation for this and I have found very little online.

I did find this, but I just didn't have the time to go down this rabbit hole. link text

not. this schematic is for the GPS Unit. (COMX GPS Module doesn't release the schematic yet).
I paste it here just want to tell you the PIN28 of the M5BUS is 5V output. (if you are using the CORE1，you even could use this pin for input or output)

just like I said. The newer boards (COMX.GPS Module). don't have PPS output.

@m5stack Comooon. You must do it! Why still haven't any code? I'm buy module COM.X GSM but how run it?

@stantheman
You don't need to check anything, just configure spi for lower speed.
There is not much sense in using fast spi clock with LoRa module, 1 MHz is probably enough.

BTW, there are some LoRa modules which operates over serial port (UART) which are quite easy to use (like this one or this one).

LoRa-E5 (STM32WLE5JC) Module is also very interesting and supports LoRaWAN too.

@lgx
Thank you for your information.
4 Relay works OK directly connected to Core2.
But how can I connect it using PAHUB ?
