    • RE: UIFlow 1.8.2

      @m5stack Does it support BaseX? I could not run the same UIFlow script (previously worked) to drive the BaseX.

      @ksprayberry Thanks for responding. Have you checked also this issue with the BaseX ?

    • Why the newest UIFlow does not support BaseX anymore?

      For the M5Stack persons in charge. Why the newest UIFlow does not support BaseX anymore? I have posted in the module section about this issue but it seems the MStack persons do not respond at all. Is there anything I can do? Can I get older firmware that still supports the BaseX? @lukasmaximus @m5stack

    • RE: Name 'module' isn't defined (BaseX with UIFlow)

      @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!

    • RE: Name 'module' isn't defined (BaseX with UIFlow)

      Hi @felmue
      Thanks for the effort to check. Unfortunately, I forgot the last version of the firmware which worked well. This makes me sad (and angry actually). The problem is I could not roll it back because I could not find older versions in the M5Stack repository. So what should I do? It is an expensive base and I need it to drive my Lego motors for my recent project. The M5Stack and its base module are commercial products but the quality assurance of the software and firmware are questionable. I hope the M5Stack people in charge would handle this issue quickly.

    • Name 'module' isn't defined (BaseX with UIFlow)

      Dear Member,
      Up to now, I could use UIFlow and BaseX well with my M5Fire. Recently I updated my UIFlow(Fire) to version 1.8.2-fire and suddenly I couldn't run my script anymore. What is wrong with the new firmware and/or UIFLow IDE? I have tried both the online and offline versions of UIFlow. The results were the same.0_1628914371379_IMG_20210814_130830.jpg 0_1628914379801_IMG_20210814_131007.jpg

    • RE: [Solved] GPS Unit (AT6558)

      @vkichline said in [Solved] GPS Unit (AT6558):

      @liemph; I'd be happy to share my code, but all the GPS-related parts can be found in the product examples here:
      https://github.com/m5stack/M5Stack/tree/master/examples/Unit/GPS_AT6558
      The example is pretty complete, but unreadable.

      The project I'm working on is more display oriented, and most of the code is a nascent control class I'm playing around with for solving general display problems. You're welcome to take what you like from it:
      https://github.com/vkichline/GPSTest

      I plan to pursue the display controls in another project, so I won't be updating this one.

      Thanks a lot.

    • RE: ENV+Relay

      Check the pin layout of the two units:

    • RE: ENV+Relay

      @Kris The ENV unit uses I2C interface while the Relay unit uses a single bus (simple digital i/o) interface. For example, if you use M5Stack Fire, as default, the ENV unit is connected to Port A (I2C) and the Relay unit to Porb B (I/O). For some reason, if you really need to use Port A for your Relay unit, of course, you can. But you have to carefully program the correct pin of Port A to work as an output port to control the relay. To be more precise, the pin for SDA of (I2C) (yellow color) of Port A should be programmed to be an output pin (corresponding to the REL pin of your Relay unit). For this particular case, the fourth pin (SCL, white color) of the Port A is not used. The same grove cable can be used for both units. Good luck.

    • RE: Two cores broken?!

      I bought it from the official store in Aliexpress:
      https://www.aliexpress.com/item/4000481165186.html?spm=2114.12010612.8148356.1.eed67573HQiQdi
      The base has also a battery included, so it will work without external power supply. But if you drive motors for a long time then you need to supply with external power. It has a DC connector for this purpose.

    • RE: Two cores broken?!

      @gabriele That is the most regretful part of buying Fire. Now I am using the Fire with other bases such as Base-X for playing with my Lego motors. In this case, you definitely have to unplug the battery base.

    • RE: Two cores broken?!

      I also have difficult times with M5Stack Fire particularly. The symptoms you mentioned also occurred in the past. The last resort I have done and it seems working is by opening the base which contains the battery. Unscrew the base, detach the base from the CPU. Connect your USB cable to your PC. The Fire will respond. Good luck.

    • RE: How do I use L298N motor driver with M5StickC

      @anuj01 Another alternative is to use the M5 official IO expander unit.
      https://m5stack.com/collections/m5-unit/products/official-extend-serial-i-o-unit
      M5StickC has an I2C grove port, and you can connect this unit to it. I have tested and it works. Good luck.

    • RE: Bug? uiFlow 1.4.5 Stick C IMU ypr[] (getX and getY) values are weird.

      @ipodlux For the time being, I stopped using uiFlow (or Python) for IMU related project. It is not reliable and it is slow. Use Arduino IDE, you will have a much faster code and reliable result.

      @m5stack said in [Solved] GPS Unit (AT6558):

      @m5stickfreakler if the "old" GPS has problem, pls contact our store.

      I bought a GPS Unit from Aliexpress and it seems old since I faced the same problem with @M5StickFreakler. What store should I contact for this issue?
      Just now I contacted the M5Store from the Aliexpress homepage.

    • RE: Compile error - ImportError: No module name serial

      @rexlee I assume you use Arduino IDE. What example did you compile for your M5Stick C? If it was your own code, then please upload the code so other members can take a look.
