Arduino for STM32

what about USB HiSpeed 480Mbps with stm32, is it possible that we can get some fraction of it or half of it ?

I want to send 25kb of data in few milliseconds, max 5ms

use Serial.write(buffer, size); instead of Serial.println that could improve things. in USB CDC serial, the polling is controlled by the host, and if you have many other peripherals e.g. mouse, keyboard, hubs etc, slots are assigned by the host, and it would reduce the polling slots to your device....

Is there any example of USB CDC, I want to transfer data at higher rate, but found no example related to that with stm32 arduino core.

how to use std::vector<> in stm core

Hi, I'm changing my project core to newer one of stm32duino. I'm getting many many errors, which is expected. But the problem comes when a library becomes incompatible at fullest. One of which is https://github.com/mike-matera/ArduinoSTL. It was working fine on Steve's core but not on new core v.2.0...

Hi there, I've been using RogerClark's core and the first build used to take a minute or half but after first build, it takes around 5 to 10 seconds. But with this new core, the first build is like 10 minutes and after first build, it takes 3 minutes each time. So if I make a little change like upda...

I dont know how but PH1 is working itself and I did nothing extra.

Thank you for all the quick and meaningful replies, have a good day.

Well which connector you used to test? For PC8 and PC9 there are not connected by default to the Morpho connector as SB are DNF by default: PC8-9_H743.png I'm using both CN11 and CN12. Yes you are right, PC8 and PC9 have SBs DNF by default. I was focused on PF14, I forgot to check these 2. Thank yo...

okay I will avoid PH1 but what about PC8, PC9, PF14 not working as INPUT

I checked the entire PCB as its open source, there is nothing attached to PH1
