Re: Using an SSD1306 as 7-segment display

I made a library for 7-segment displays using the TM1637 LED driver, used by the SeeedStudio Grove 4 digit display: http://forum.micropython.org/viewtopic.php?f=14&t=2781&p=16525 Not as cool as an OLED though! Nokia 5110 LCD (PCD8544) next? The Nokia display uses a lot less power. (0.4mA vs 5-13mA f...

Re: VCC-GND STM32F407VET6 dev board

Board definition moved here:
https://github.com/mcauser/VCC_GND_F407

Using @dhylands approach, with separate git repos per board, and clone them into stmhal/boards when needed

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

That's how all of the other mpconfigboard.h's do it. RTC is defined after HW_CLK
eg. https://github.com/mcauser/micropython/ ... figboard.h

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

@kid06 I noticed this too and can confirm adding MICROPY_HW_RTC_USE_LSE(1) to mpconfigboard.h enables the datetime to persist between power cycles. When I first enabled it and uploaded new firmware, rtc.datetime() would only output 2000 and not increment: >>>rtc = pyb.RTC() >>> rtc.datetime() (2000,...

Re: New chip ESP8285

Wemos.cc are releasing a new ESP8285 board sometime next week. They are calling it the "D1 Mini Lite". Details are a little sketchy. I presume it is going to be a similar form factor as the breadboard friendly D1 Mini. Edit: https://www.aliexpress.com/store/product/WEMOS-D1-mini-Lite-V1-0-0-WIFI-Int...

Re: Flashing firmware with filesystem

It would be nice if there was a /flash folder in /esp8266 which, on make, would append each file to the flash filesystem.

Then we would have 3 methods for deploying scripts, /scripts, /modules and /flash.

Mine took 33 days to get delivered to Australia. Chinese new year celebrations have caused a few of my orders to get delayed.

MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

I've created stm32 board definitions for these two MCUDev boards from China, labelled STM32F407XX. For lack of a better name, I've simply called them BLACK STM32F407xx. Originally located at: https://github.com/mcauser/micropython/tree/black-stm32f407 Now, moved to their own repos: https://github.co...
