Re: Accessing pyBoard from Android via USB-OTG

Has anyone made progress on this issue? I'm working on an Adafruit STM32F405 Feather Express, with the firmware Adafruit provides at https://cdn-learn.adafruit.com/assets/assets/000/083/671/original/micropython_1.9.4_Feather_STM32F405.zip?1573009976 I'm ...

Stepper motor drivers

I'm not exactly up to date on this. I last drove stepper motors about 45 years ago ;) I guess something like this should do. It's designed for Raspberry Pi, but as far as I can see it's just an I2C interface. Ideally you want a driver that allows you to control acceleration and deceleration as well ...

Re: Vbat use

Yop,

Ok, I understood that there isn't a way to charge a battery on pyboard (with fet diode).

No way. I have to use a specific charger like the powerboost 1000c from adafruit for doing that.

I have seen that it looks possible with the pyb-D and wbus28...

Re: Anyone have drivers for FXOS8700/FXAS21002 (Adafruit NXP precision IMU)?

There are CircuitPython drivers for both the FXOS8700 and the FXAS21002 . Both will be trivial to port to MicroPython - just change some references to the way I2C is handled. Let me know if you get stuck! I'd also suggest a design change: just pass an I2C object to each of the drivers rather than cr...

I am not aware of one. You will find various IMU drivers at micropython-imu. If you need sensor fusion I recommend the BNo055 which performs it on-chip with great effectiveness.

Anyone have drivers for FXOS8700/FXAS21002 (Adafruit NXP precision IMU)?

In some google searching I did not find a micropython driver for the FXOS8700 or FXAS21002. If anyone knows of one I would appreciate it if you could post it or send it to me or something.

Thanks

Re: problems with as_GPS

That is odd. I don't think I've ever seen a CRC error from my Adafruit GPS. I can only think they come from the GPS module.

Re: bno055 - i2c problem. ETIMEDOUT.

... I2C are usually down to pullups or overly long wires. I have never seen this problem and tested with hard and soft I2C with no special args. My Adafruit breakout board has pullups. Excellent choice of IMU, by the way. The built-in sensor fusion is awesome.

Re: ulab for ESP8266

If you want to make ESP8266 with ulab available for everyone, you should simply write and publish a script that modifies the above-mentioned three files, and then you are done. We can do that in the ulab repository, if you would like. The branches that I'm citing have the modifications listed. Anyb...
