Re: Ideas for next evolution of pyboard

or maybe you could provide something along the micro:bit. - re-selling the original (for the rest of the world...) - a compatible board (though if you add more resources/better MCU, it won't be compatible to the existing online editor etc :/ - though a more powerful but pin-compatible board (even if...

Re: Ideas for next evolution of pyboard

The current pyBoard has a nice form factor and stands out against other boards, the X/Y position for shields is smart. That's probably worth to keep. I also like to have a micro-USB connector as its very easy to get started (with the serial port / mass storage or just to provide power). Also useful ...

Re: STM32F407 Discovery size of flash drive

Well the recent work towards bytecode that can be loaded from files or linked with the firmware image may become helpful. it would be thinkable that libraries get linked to the firmware, using that extra flash memory. in such a scenario, that flash does not need to be a writable filesystem. an other...

Re: soft-reset unreliable w/ SD card

@hugohase
no, i did not.

and i would not like to do more than initializing them as GPIO. the point of an SD driver in the firmware should be that i do not have to do the lowlevel stuff on my own ;-) though one could still blame the SD card and declare it incompatible.

Re: wipy environment

@iandouglas
well the code does not verify if there is an expansion board and handles a non existent SD card gracefully. so it should be fine without any connections. however it will initialize the pins (SD, button, led, UART), which may or may not conflict with your setup

Re: soft-reset unreliable w/ SD card

i've added a view debug prints def initialize_sd_card(): """Try to mount SD card and append /sd/lib to sys.path""" global sd try: print("..

soft-reset unreliable w/ SD card

I've noticed that the soft-reset (CTRL-D in REPL) is sometimes unreliable when a SD card is mounted and used (expansion board). The Hard reset button always works. The code instantiates the SD object and mounts to /sd, which seems to work well usually. However after a soft-reset it hangs from time t...

wipy environment

I wanted to have some configuration code run at startup and the option to put a main.py file on the SD card, so i coded something to do that. Thought that may be useful to others too. https://github.com/zsquareplusc/wipy-environment activate REPL on serial port try to connect to home network (in STA...
