Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Let me know if anyone finds a real tiny board using STM32F4 in QFN48 package. I can't seem to find one (an the one I designed myself went up in smoke :D ).

Cut the videos, your time is better spent elsewhere.

Re: ESP8266 HUZZAH breakout + LSM9DS1 9DOF

Not sure how similar they are, but maybe this helps:

A Tale of Two APIs

I believe that MicroPythons hardware API is its most important feature. There only few languages that you can use on microcontrollers, mostly by the virtue of their compiler suite - Rust, ADA and D are examples. But getting the language to run on a microcontroller is just the first step, the much mo...

Re: Esp32 make is not working

Code: Select all

make -B
also forces a rebuild.

Re: Module for MPU9150

The error is in this line of the code: https://github.com/micropython-IMU/micropython-mpu9x50/blob/master/mpu9150.py#L187 scale = 0.3 That's not a decimal, but a float. I vaguely remember the WiPy not having floating point support and the docs confirm that: http://docs.micropython.org/en/latest/wipy...

Re: Consistent bitflips when using pyboard as SPI slave and other SPI weirdnesses

I checked the SPI mode again, changed my UNIX SPI library a bit, and am now sure that both devices sue the same mode. Then I played around a bit, changing the modes to be the same, then to be different. Nothing changed, still bad communication. Until I did a spi.deinit() before reseting the board. A...

Consistent bitflips when using pyboard as SPI slave and other SPI weirdnesses

I'm using the pyboard as SPI slave and a Raspberry Pi as Master, both running MicroPython and I'm seeing a lot of weirdness going on. For example, I'm sending this (as byterray): [254, 202, 1, 0, 170, 15, 62, 32, 1] and get his on the pyboard: [126, 74, 1, 0, 42, 15, 62, 32, 0] That's a flip of the ...
