@hwtaro9 I've never seen bala 2 work with the UIFlow blocks they provide (are those even for the Bala2 or just Bala?).

When I had a UIFlow program on mine I had to set the i2c registers in python code (in an execute block), which works but implementing a PID loop in there wasn't something I wanted to do.

It would be great to have official UIFlow blocks for that robot though, it's really nice hardware.

Hello @macsbug

I've noticed that too. However there is insulation (capton tape) on the back of the speaker in my M5Stack base v2.6.

Thanks
Felix

@felmue thank you very much!

Firstly, apologies for reviving an old topic. I realise i could use base x (and indeed do own one already). However, i was wondering if there had been any progress on adding the pid functions to the api for the lego+ module. i was hoping to use with ev3 motors but was looking to have both speed and position control.

many thanks.

Do you need of the shelf product? couldn't find any but I'm sure it can be pretty easy to make one using 3D software and print it using a 3D printer. On thingyverse you could find a lot of great examples.

@ajb2k3 said in Micropython - SHT30 in BTC Base:

Micropython on the M5Paper is in early alpha because we pushed M5Stack to get it out before the holiday. I spent yesterday doing some testing and I cannot get any SHT30 devices to work no matter if its the internal SHT30 on the paper or the env2 unit.
What lib are you using as I cant even get raw reg read and writes to work.

For now I have abandoned micro python and switched to (yuck) C and platformio.

Thanks to @MattM who solve problem in Bala2 example code will compile but running the code does not progress past calibration. <SOLVED>

Two DC encoder motors ( 9 - 12 V).

@m5stack Many thanks for the quick help. With the spare part the BALA now works perfectly!

You should charge your battery to full. Do you tried to calibrate your sensor?
Press and hold the right C key to start the machine, and release the key after hearing the "drip" sound. The sensor will enter the calibration setting, and keep the host horizontal and still. After 3 seconds, the sensor calibration is completed, and it will automatically enter the balance mode after the calibration is completed.If you found that Bala cannot keep balance during use, it can be solved by trying to calibrate the sensor.

@jkinsky yes, that will be fine as comments get flagged as unread posts.

I don't think he means controlling the faces II base itself, I'm sure he means you can communicate with a module that uses serial comms mounted on the base using a grove cable from a separate m5stack core (with a serial port or pins).
The grove port on the m5stack will supply the power for the module on the base and serial tx/rx data will be transferred over the cable instead of directly over the internal M-BUS. Which is how it will usually work with a stack of modules under a m5stack core.
I'm not sure if this "remote" serial cabled comms is actually very useful in the real world.

Edit: I just realised that the faces finger board uses serial (uart), so you could put a fingerprint faces board on the faces base and communicate with it over blue port c using pins 16/17 from a separate m5stack core.

This is already requested some time ago via git. Still not filled.

Hi @Happy-Hippo if you press the pogo pins do they spring back fully? or get lodged? usually there is a bit of a gap but it shouldn't affect normal operation

After 3 successive orders, the bases have all three a defect of connectivity.
I think the heights of the pins of the contacts are not high enough and do not fit in the header.
