Arduino for STM32

Okay. Thanks.

I asked a question recently, and got a reply but I had to poll for it - I didn't get an email notification despite having these options set:

I have enabled USB CDC, yes, but out of habit. I think I needed that for the STM32F407G Discovery. I didn't know the consequences. I thought I had to do that to get USB serial output at all.

I'm still not entirely clear what those options do. The descriptions of them in the Arduino Tools menu are a ...

How can I find which USART is connected to Serial , on the Nucleo-144 STM32F746ZG? I've searched, and looked at the variant definition, but I can't figure it out. It's currently connected to the user micro USB port, by default.

What I'd like to do is define the ST-Link one as Serial and have the ...

It's usual to have something like this, in setup() :

Serial.begin(115200);

- but there's an optional second parameter, called config, which has more options, so you can set things like parity, number of stop bits, and so on, by choosing a configuration off a list of alternatives.

Here's the ...

I've never really used them, but that looks useful, just as it is.

It seems like a good way to keep up without having to dive into different areas of the forum to check them all.

Could we have a link from the main site, maybe in the header of each page?

My impression is that I2C reads are blocking, which introduces occasional delays on the other periodic operation (samples processing + SPI). Is this really the case? If so, is there any workaround?

I2C/IIC is fairly slow, so you'd probably need to make sure each operation didn't happen until ...

That sounds promising. Thanks, fpiSTM.

Currently, I'v made no change on how phpBB manage search.
I'm open to all suggestion to optimize it anyway I guess the default should be fine regarding phpBB legacy.

I used to use a radio control forum which used phpBB, and looked similar to this one. The search got progressively worse, until it ...

I hadn't seen this thread before. I was effectively asking the same thing, yesterday, but I was thinking more of parallel I/O. This thread has a lot more of the details than I managed to find, so I've linked to it, from there:
