ping on lan doesn't work

Dear, I have been using uPing.py to do a ping from my PYBD-SF6 board and this works great. Then I use a F7 with a wired LAN connection and using uPing and no response comes back. The other way around a ping to my board is echoed, but that is handled within lwIP. The checksum generated are correct an...

Using a piece of code implementing a ping function works well using the PYBD board. However, using the same code (except LAN/WLAN differences) on the NUCLEO_F767ZI using the Ethernet LAN connection does not read back data.

STM32 MCO OUTPUT

The STM32's have a possibility to bring out a clock signal called `MCO`. It takes one of the selected clock sources, puts it through a divider and brings it out to a GPIO pin. I use it to spare a crystal in a design. Be aware that when having a long wire attached to the pin, you create a nice transm...

Dear all,

Did anyone find or has written (and willing to publish this under MIT) a driver using a TMP75 I2C temperature sensor?

Beste regards,

Re: [LEGATO] Running mpy on legato's linux
