@laursena and @HappyUser
I am also trying to get RFID 2 to work with PaHub and running into similar problems:
MFRC522 mfrc522(0x28);
You mentioned to get an update version of ClosedCub.cpp? I don't have the directory in my library folder, could you please be more specific. (I also googled it but out of luck there as well).
Thanks,
Hi all,
I just got my hands on a Ext. I/O 2 Unit to read 3 potentiometers. I and using the official ADC Input example code from here (https://github.com/m5stack/M5Unit-EXTIO2/blob/main/examples/Unit_EXTIO2_M5Core/ADC_INPUT/ADC_INPUT.ino)
It reads the data, but the number went to 4095 (max value) before the potentiometer is fully turned. Actually, if I position the knob right at the middle, it show 3160 on the screen. What did I do wrong? How can I have it cover the whole rotation?
many thanks,
Hi all,
I have been working with M5Stack since 2020, it really checking all the boxes of what I wanted for a micro controller. I am currently working with M5Stack Fire, and the battery base comes with a 500 mAh battery. However, I need more juicy to keep it running longer wirelessly. I am powering a set up of a Neoplixel ring, a RFID 2 unit, a limit Switch unity, and potentially a vibrator unit.
Due to size of the housing, I decided to create a Type C power cable with following parts to keep it low profile:
I soldered the red wire to the V+ and black wire to the G. However, this DIY power cable only works when plug in with a Type C to Type A cables (power source) and not Type C to Type C (power source) cables.
Anyone know why this is happening? Is Type C to Type A wired differently? or is it because the 5.1K resistor?
Any insight will be greatly appreciated.
Thank you, you are brilliant. It is not the answer I was looking for, but thanks for explaining. I hope the world has more people like you who are willing to help a beginner. I want to be creative with technology, but don't want to be a engineer.
Okay, based on the documentation, 1-3 hub is a hardware extender which does not change units' addresses, only extend them. If the input units share the same addresses, they will interfere each other. The solution is to use a pBhub instead.
I realized Mini Button unit, OP 90 and 180 unit, Dual Button Unit examples are all using pin 36. Does that mean I can't use them together as separate inputs? There must be a way!
I wanted to use an OP-90 and a Dual Button Units together. I connected them to Port B on a M5 Fire through a 3 - 1 hub. I realized that they both use pin 36. Is there a way to change that? How can I use them together, many thanks!
