Evaluation boards arrived from STM

Guys

STM have sent me the Nucleo boards, which their code will eventually support.

These boards are

Nucleo L053
Nucleo F091
Nucleo F103
Nucleo F303
Nucleo F446
Nucleo L476

I already had a Nucleo F334, and I can’t remember whether that was on their list to be supported or not.

I also have a Discovery F4, but I don’t think STM intend to support the Discovery series at all – however I think a number of people on the forum have some form of Discovery F4, so I suspect we will end up supporting it in some way.

PS. The boards have taken a week by Fedex to get from France to Australia, because they were misslabled with the AT rather than AU country code, hence they have been from France to Austria and back 3 times before I rang Fedex to notify them that something was seriously wrong with the addressing of the package(s) – and managed to get them to update the labels

Its strange, as the delivery address was correct, so you;d imagine it would be all handled by bar codes, not by the country code printed on the box, but perhaps they still manually sort stuff!

As I understand, CubeMX passes the parameters on registers as they are (at least for I2C)…. For proper operation a rather complex calculation is required, while this is not a big problem, the different parameters for different clocks, is.
I will check the mbed and Chibios how they solve this problem…..

OK.

So we could use mbed’s I2C values for 80MHz

We have taken account your remarks about the STM32L4 system clock settings.
A new release will be soon available with the new settings:

system clock at 80MHz
SPI default speed at 5MHz
I2C clock settings updated

Excellent…

Thanks
