Re: ssd1306 display scroll

How does the hardware scrolling work? Here's how it works in an Arduino example: https://github.com/adafruit/Adafruit_SSD1306/blob/master/Adafruit_SSD1306.cpp#L330 The hardware display buffer is 128x64, so if you are using the SSD1306 with a smaller OLED, such as the wemos 64x48 OLED, scrolling reve...

Using a Nokia 5110 as a 7-segment display

I've created a library for emulating a quad 7-segment LED display modules using a Nokia 5110 display with PCD8544 driver: https://github.com/mcauser/MicroPython-ESP8266-Nokia-5110-Quad-7-segment Based heavily on my tm1637 library, for SeeedStudio Grove 7 segment displays: https://github.com/mcauser/...

Re: Using an SSD1306 as 7-segment display

I made you a Nokia 5110 version. Here is it running on my ESP8266: https://github.com/mcauser/MicroPython-ESP8266-Nokia-5110-Quad-7-segment The first version I made used bytearrays for each digit, but this proved to be much larger than just drawing individual lines to make up each segment. # digits ...

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 ...

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
