I can't imagine this hasn't come up before, but I searched and came up empty. So, apologies for what is surely a repeat!
Is there some easy way to set the speed of the console serial port? 115,200 is really nice when working on the ESP8266. Surely the STM32 family can handle that -- and I'd expect much faster.
I'd love to be able to set my Pico to 115,200. I'm guessing I can do it with the right call to Serial.setup() maybe, but I don't know the particulars of setting up the port to talk to the IDE (bits, parity, etc.).
Yes, it's literally just Serial1.setup(115200) that you need. Then you can connect to the IDE at 115200 baud using the B6/B7 pins and a USB-TTL converter.
However are you connected via USB? If so, the console on USB ignored the baud rate and is already running as fast as possible over the USB connection - it should be way faster than 115200 baud.
Well, not sure about the details of USB... NOT connected directly to the STM32 via the direct USB support. Rather, I'm connected via USB to a Prolific USB->Serial chip on the board that then connects via normal serial to UART function on two pins on the STM32.
This is an HY-STM32V with the 3.2" touchscreen. The serial connection from the USB chip is connected to pins A9/A10 TX/RX.
I tried what you posted above, and got this result:
Uncaught Error: Function "setup" not found!
at line 1 col 8
Reviewing the Serial class documentation, this makes sense -- don't I have to have an actual instance of the Serial class to use it? The documentation talks about pre-instantiated instances Serial1, Serial2, ... and USB.
So, still stuck. And, there's no doubt it's 9600 baud :-)
My main issue here is that at 9600 baud loading the GUI code I'm developing takes a long time, which is painful with edit/test cycles.
Gordon, here's some more interesting "things": There are two USB connections on the MiniSTM32V; one goes through the Prolific chip and connects to a pins configured as a UART. This is where the console is configured by default, running at 9600 baud.
The other USB connector is connected directly (with buffering) to the STM32, on pins A11/A12/B7 as USB_DM/USB_DP/USB_EN. I've largely ignored this connection to this point, as it was not responsive with the IDE -- I was able to connect with the other "USB" connection.
So... If I could move the console over to the actual real native USB connection, and get awesome speed, that would be ideal. I suspect it's simply a matter of configuring those pins for a native USB connection, then directing the console there -- how do I do that?
BTW sending another U$25 to keep supporting you guys... thanks for everything!
Serial**1** is the instance of the a Serial that is used...
Serial1.setup(115200); // notice: Serial1 (Serial # One)
A9/A10 - USART1 (USART - Universal Synchronous/Asynchronous Receiver/Transmitter # 1) IS Serial1 - as per HW reference for HYSTM32_32.
As @allObjects says, you need the Serial1 like I posted, not Serial.
If you're not getting any response from the on-board USB, I think it's probably just that you need to install the drivers mentioned in the Quick Reference?
Drivers was it... up and running, @Gordon, and blazingly fast! Coding is SOOOOOO much better!!
Turns out I had installed the STM drivers weeks ago, but the COM port installation looked like it was hanging, so I killed it and stayed with the serial. Forgot about that until you mentioned the Quick Reference.
So, plugged it in again, and waited it out this time. Took a long time, but eventually finished successfully and I was able to connect. Thanks!
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
