Hi there I was just wondering, if anyone ever though or did some work of porting https://github.com/littlevgl/lvgl to Micropython? There is a port of Micropython to LittleVGL (which is the other way https://blog.littlevgl.com/2019-02-20/micropython-bindings or https://github.com/littlevgl/lvgl/issue...

Hello

The F723 is currently out of stock. When will there be a new batch?

Greetings

Hi I was playing around with the x7 ports for STM32. I tried to debug on my Nucleo H743 board so I ssued the command: make BOARD=NUCLEO_H743ZI DEBUG=1 -j4 which resulted (after deactivate the MICROPY_HW_HAS_SDCARD #define in mpconfigboard.h) in the error: build-NUCLEO_H743ZI/py/objfloat.o: In functi...

Hi there
The board is now supported in MASTER.
I am looking for feedback.

See PR #3745
Looking forward to test results and feedback.

Running your script on my STM32F407G-disc and connecting the PA0 to 3V works and gives me the value 4095. As VREF+ is - more or less - connected to VDD (~2.95V) I assume that you only connected 2.5 V to PA0?

The #define fix does not work on my board. However after a longer debug session I discovered, that calling the init() from MicroPython on the RTC starts the clock - which is not needed on the F4 - even without the #define in the header file. If you look on the clock-tree of the L4 (eg. CubeMx or ref...

I moved the stuff in a new, more general repo:

Have a look at the STM32L476-discovery design:

Use it as starting point for your design.

@bobricius: The presentation you mentions is from September 2014 and discusses USB clock recovery on F0/L0 done in a way as @marfis described. BTW there is an application note by NXP (AN4905) describing crystall less operation on Kinetis MCUs. Further in the Marketing presentation you mention they s...
