Arduino for STM32

Hello,

So, I changed this line 134 in variant_NUCLEO_L476RG.cpp to:
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1; --> RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV2;

Now clock is changed 80Mhz to 40Mhz, enough to get a baudrate of 1200.
Final serial configuration --> Serial.begin(1200 ...

Hello,

I've been digging a little bit... I found to get 1200 baudrate I should down the clock frequency.
Now, I'm trying how to proceed with it.
Another point is to use SoftwareSerial and manage 7bits Parity even manually.

I hope I can share with you my results.
Any help or comments will be great ...

Hello,

I'm trying to set a Serial communication with baudrate of1200, 7 databits, parity even.
Actually, it is for a SD-12 communication.
Anyone knows how set a Serial with a baudrate of 1200?
I tryed to use SoftwareSerial to get baudrate 1200 but then the issue is with databits and parity ...
