UHF RFID Unit (JRD4035) on M5Core2

[tobias.h]

I was wondering if the examples from the M5Stack Repository will be re-released on the M5Core2 repository. Unfortunately I am not able to get my JRD4035 running on a M5Core2. Anybody maybe has experience in this or info when examples will be released?

Best wishes

Hello @tobias-h

you could try to modify the M5Stack example yourself.

Replace below line:

#include <M5Stack.h>

with

#include <M5Core2.h>

and below line:

Serial2.begin(115200, SERIAL_8N1, 16, 17);//16.17

with this line if you connect the unit to port A (found on M5Core2):

Serial2.begin(115200, SERIAL_8N1, 33, 32);

or this line if you connect the unit to port C (found on M5GO Battery Bottom2):

Serial2.begin(115200, SERIAL_8N1, 13, 14);

Thanks

Not sure if this will help.

I made a quick reader based on a [project I'm working on this also works on m5Paper as well it's nothing complex simple read and display, this is on a Basic Core unit
A quick video showing it working
https://youtu.be/qvtr6Vy-HwY

The Tags I use are these ones

make sure the port is correct otherwise the bytes out of range error pops up
I hope it helps

from m5stack import *
from m5ui import *
from uiflow import *
import unit


setScreenColor(0x222222)
uhf_rfid_0 = unit.get(unit.UHF_RFID, unit.PORTA)

uhf_rfid_0.set_region(uhf_rfid_0.REGIN_US)
uhf_rfid_0.automatic_freq_hopping(0xFF)
uhf_rfid_0.set_channel_freq(924.25)

uhf_rfid_0.set_select_mode(0x01)




label0 = M5TextBox(128, 59, "Tag #", lcd.FONT_Default, 0xFFFFFF, rotate=0)
label1 = M5TextBox(22, 106, "waiting ... ", lcd.FONT_Default, 0xFFFFFF, rotate=0)


while True:
        # while not temp:
        temp = uhf_rfid_0.single_polling()

        if temp:
            # label10.setText(str(temp))
            print("-----")
            print(temp[0])
            print(temp[1])
            print("-----")
            label1.setText(temp[0])
        wait(.5)

@kylebuttress Hello,
Thanks for your example, installed vScode IDE with python and program your example.
It works the same as in Fixow and Arduino. It only shows 6 EPC characters and only reads some EPCs.
It is very strange that with all the examples on different platforms the same thing happens.

Thanks for your help,

@kylebuttress
Hello again,
This is the information that I visualize from the EPC.
[From M5Burner] Com22 Opened.

30395D
-30

On the Core 2 screen, it is 30395d.
When the complete EPC of the label is 30395DFA835F7E4000466D16
I don't understand anything, both in the Core2 and at the Atom.

Cheers

Hello everyone
Nobody with M5Core 2 and UHF RFID UNIT (JRD4035) running properly?
Cheers.
