Arduino for STM32

@Greirat : Sorry but the FlashStorage_STM32 not working like you describe ! you describe the use of the "original" FlashStorage from cmaglie ! BUT the FlashStorage_STM32 is not a clone! it's just implement the eeprom like API

So please test the code you gave before answered, especially for beginner ...

Surely you are right but the objective was not to make an optimum code.

Your position is the one of "advanced" or "specialist" but think about all beginners or hobbyist?
these small post just illustrate how original STM32 arduino gpio writing is slow and how we can easily get better ...

I play again a little and "Overclock" to 128MHz ... working at my room temperature ( I live in SIberia ! )

GonzoG PLease give us your code ! (I do not pretend to get the fastest .. just starting to play)

Next .. What is the STM32Duino system clock setting ?? well I have a stm32F103C8 and you could found the setting here :

"C:\...\AppData\Local\arduino15\packages\STMicroelectronics\hardware\stm32\2.6 ...

Need Faster ?
F = 7 MHz!

Hello all,

just a small example to illustrate how to speed up your IO.
STM32 Arduino core use HAL interface to write or read IO. HAL is know to be very slow.. but how mutch slow?

Here a test, made on STM32F108C:


//Here a classical arduino write -> use STM32 HAL interface -> F = 396 KHz
do ...

@fpiSTM:

Yes, this is an hard issue !
Why ? because when I started to work with this board I modified the stm32CubeProg.sh like it command RTS and DTR line (on my board RESET condition is achieved with RTS = 1 and DTR = 0, Boot mode is with RTS = 1 and DTR = 0 ). But I didn't release correctly ...

@ag123 :


HardwareSerial Serial1(PA10, PA9);

void setup() {

// Serial.setRx(PA10); // using pin name
// Serial.setTx(PA9);
// Serial.begin(115200);
Serial1.begin(115200);
while(!Serial1);
}

void loop() {
Serial1.println("STM32Duino Forum !!!");
delay(200);
}

This code work, BUT only ...

@fpiSTM : no this not working

Same with Arduino IDE 1.8.19
