F7 SPI clock about ada_drivers_library HOT 3 CLOSED

Hi @morbos,

What I would do is to change the Send_8bit_Mode procedure to use a different hardware mapping than This.Periph.DR.DR. For example:

procedure Send_8bit_Mode
     (This     : in out SPI_Port;
      Outgoing : HAL.SPI.SPI_Data_8b)
is
   [...]
   Data_8bit : UInt8 with Volatile, Address => This.Periph.DR.DR'Address;
begin
   [...]
   while Tx_Count > 0 loop
      [...]
      Data_8bit := Outgoing (Index);
      [...]
   end loop;
   [...]
end Send_8bit_Mode;

This should force the compiler to use 8-bit writes.

HI Fabien,

That works! Slight mod to make it happen though:

Data_8bit : UInt8 with Volatile, Address => This.Periph.DR'Address

Without that omission of the second DR, it does some odd 16bit sign ext and leaves the address as a ram local.

Thanks!

Cool! Don't hesitate to submit a fix ;)
