Is there an adapter to use with the existing DC encoder motors that come with standard JST connectors like this (https://www.robotshop.com/ca/en/lynxmotion-12v-450-rpm-1018oz-in-152-brushed-dc-gear-motor-w--encoder.html)?

I would be very interested in getting your adopted code. I have not been able to get the thermal unit to work with any of the examples.

@felmue said in GoPlus2 Port B with servo with UIFlow:

Hello @xs

I think you are out of luck here. A servo requires a PWM (pulse wide modulation) signal, however the three B ports on the GoPlus2 are only good for simple input and output signals but cannot do PWM.

The GoPlus2 description reads: Three PORT-B interfaces(Analog Input,Digital Output,Digital Input) can be expanded.

And looking at the GoPlus2 blocks in UIFlow the digital output can only be set to 0 or 1, but nothing like PWM.

Thanks

Thanks, that's what I want to know. I'll use the B Port in the M5Go base instead. Thank you so much.

更新到最新版IDE后，上述功能被移除了。
CORE2连基本绘制几何图形除了线之后都是程序实现了。
但是程序绘制后和LCD交互有些问题，估计要等IDE进一步升级解决了
另外，强烈建议IDE开发成PYTHON交互的，现在的只能图形编，程序那边只能参考啊。

@felmue said in COM.X 915 Doesn't respond:

AT+LORAWAN=?
Thank you for the help. That was all it was. I fired it back up again and issues commands from the correct command set and it seems to be working. Now to try it out more.

Thank you!

Hello @bob_isat

all COM.X modules have an internal DC-DC converter which takes the voltage applied at the external power jack (from 5 V to 12 V) and converts it to 5.4 V (or less).

The M5Stack device (if powered from the COM.X module) always gets those 5.4 V (or less) from the output of that internal DC-DC converter (independent of whether switch S1 is set to 5 V or 12 V). So no, the 12 V are not being sent to the M5Stack device.

The switch (S1) only selects the voltage going to the LoRa board, which can either be the voltage applied at the external power jack (if S1 is set to 12 V) or the 5.4 V output from the internal DC-DC converter (if S1 is set to 5 V).

On the LoRa board itself is yet another DC-DC converter which creates 3.3 V for the LoRa chip. It's hard to find the proper datasheet for this DC-DC converter, but I think its input range is up to 18 V. So feeding it with 12 V should be fine.

I know, it's quite confusing and it took me more than one attempt to figure it out (and I could still be wrong).

I personally set the switch (S1) to 5 V and use an external power supply set to about 6 V. This allows the internal DC-DC converter to actually produce 5.4 V which then is used for both the LoRa board and the M5Stack device.

If you only use an external power supply with 5 V then the internal DC-DC converter will only produce about 4.7 V (which might be marginal in some cases).

Thanks
Felix

Hello @bob_isat

cool. Glad you got it working. And thanks for reporting back.

Thanks
Felix

Same porblem here. I've burned the newest firmware and use 1.8.3. Only function woks, is on/off, invert. I cannot change what to display.

It is very shame that the product is not accompanied with any documentation.
Where is the detailed schematic?
Where is the description of the FW?
Where is the description of RawDisplay SW?
Where is description of the passthrough serial?
Where is protocol description?

@world101 No worries! Thank you so much!

@m5stack @lukasmaximus Could you help to resolve this issue? If the new firmware is not yet fixed, please provide the older version which I can use. Thanks!

Hello @inkto

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

Thanks
Felix

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.
