WeAct Studio STM32F411CEU6 BlackPill v3.1 crystal is 8 MHz

[Fziegler_076]

Hello friends!

I bought a new version of the Black Pill v3.1 board (WeAct Studio) with HSE 8 MHz.

The standard version of the board is available with HSE 25 MHz, and this board (easier to enter dfu mode by usb)
was made with HSE 8 MHz and it does not work.

Please tell me in detail what and where to fix so that the board works in Arduino.
I am a novice specialist and I really need to launch this board.

I will be very grateful for your help.

Simply redefine HSE_VALUE using hal_conf_extra.h.
See the wiki.

Hi fpiSTM !

There is no such file. I need to create it myself in the catalog C:\Users\Admin\AppData\Local\Arduino15\packages\STMicroelectronics\hardware\stm32\2.7.1\variants\STM32F4xx\F411C(C-E)(U-Y)?

Or does it need to be created in another directory? I looked at the Wiki, but did not understand what needs to be entered there.
Only one line #define HSE_VALUE 800000000U or something else needs to be added to this file?
Could you help me write the contents of this file?

So simply create the file with at sketch level :
#define HSE_VALUE 800000000U

I created the hal_conf_extra.h file with a single line #define HSE_VALUE 800000000U and put it in the folder with the sketch, next to the blink.ino files.
The program is loaded into the microcontroller, but the LED does not blink.
I use the standard Blink program from the examples

Code: Select all

// the setup function runs once when you press reset or power the board
void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

Why doesn't it work?
What could be the problem?
I checked on 3 boards.

Is the LED_BUILTIN correct for this new board?

Pay attention it seems you set 80MHz and not 8MHz

1. I fixed it to #define HSE_VALUE 8000000U


2. I wrote the LED pin myself (PC13)

Code: Select all

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(PC13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(PC13, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(PC13, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

It doesn't work anyway (

What else can I check?

I have attached my project

You should redefine the system core clock config to properly configure the pll vs the HSE value.
