Hello eveyone,

I need help. The function provided by Spectrum Digital
"DSK5510_mset" works.
But, the following function doesn't work

void DSK5510_mset (uint32 m_addr, uint16 m_value)
{
*((uint16 *)m_addr ) = m_value;
}

Is there something else mising in this function?
What can I add to this function to make it work like
the one provided by Spectrum Digital?


It would be more helpful if you gave a little more information than just "it doesn't work" - not everyone in comp.dsp is telepathic.

At a guess you're running into compiler optimisation issues when trying to write repeated values to a register, in which case you probably need to do something like this:

void DSK5510_mset (uint32 m_addr, uint16 m_value)
{
*((volatile uint16 *)m_addr) = m_value;
}
