Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

My boards shipped with a "blink sketch" and no USB support. Once I installed MicroPython via a USB serial programmer (using Tx,Rx pins), I was able to use the USB port as a mass storage device. If I erase my flash and upload an Arduino IDE sketch, my USB port will stop working again, unles...

Re: Driver for LCD display Nokia 5110

Change Din <=> Y7 to Din <=> Y8. Y7 = miso Y8 = mosi vcc should be connected to 3v3. This is how you power the display. BL is the led backlight behind the display. You can either connect it to a GPIO pin and control it with software, or connect it to 3v3 to have it always lit. The display is readabl...

Re: Driver for LCD display Nokia 5110

I wrote a library for the Nokia 5110's PCD8544 lcd driver: https://github.com/mcauser/micropython-pcd8544
I have it working with an ESP8266, but changing it to work with the pyboard should be straight forward.
See the readme for examples.

Re: PADI

I bought one of those B&T RTL-00 modules, which is apparently almost pin compatible with ESP-12E modules. Never got around to actually programming it yet... https://www.rtl8710forum.com/viewtopic.php?f=10&t=10&p=23#p23 It can be programmed with Arduino IDE: https://hackaday.io/project/19...

Re: I/O expander

@deshipu Good idea using the boot-mode resistors. I'll be using that from now on :D
