Hello there, I was working on TouchGFX and when i tried to build my code i got
error: no declaration matches 'bool TouchGFXHAL::blockCopy(void*, const void*, uint32_t) and same for endFrame and beginFrame.
But i couldn't solve the problem.
Here is the part from TouchGFXHAL.cpp file.
bool TouchGFXHAL::blockCopy(void* RESTRICT dest, const void* RESTRICT src, uint32_t numBytes)
{
return TouchGFXGeneratedHAL::blockCopy(dest, src, numBytes);
}
/**
* Configures the interrupts relevant for TouchGFX. This primarily entails setting
* the interrupt priorities for the DMA and LCD interrupts.
*/
void TouchGFXHAL::configureInterrupts()
{
// Calling parent implementation of configureInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.
TouchGFXGeneratedHAL::configureInterrupts();
}
/**
* Used for enabling interrupts set in configureInterrupts()
*/
void TouchGFXHAL::enableInterrupts()
{
// Calling parent implementation of enableInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.
TouchGFXGeneratedHAL::enableInterrupts();
}
/**
* Used for disabling interrupts set in configureInterrupts()
*/
void TouchGFXHAL::disableInterrupts()
{
// Calling parent implementation of disableInterrupts().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.
TouchGFXGeneratedHAL::disableInterrupts();
}
/**
* Configure the LCD controller to fire interrupts at VSYNC. Called automatically
* once TouchGFX initialization has completed.
*/
void TouchGFXHAL::enableLCDControllerInterrupt()
{
// Calling parent implementation of enableLCDControllerInterrupt().
//
// To overwrite the generated implementation, omit call to parent function
// and implemented needed functionality here.
TouchGFXGeneratedHAL::enableLCDControllerInterrupt();
}
bool TouchGFXHAL::beginFrame()
{
return TouchGFXGeneratedHAL::beginFrame();
}
void TouchGFXHAL::endFrame()
{
TouchGFXGeneratedHAL::endFrame();
}
================================================
and this is part from TouchGFXHAL.hpp file.
virtual bool beginFrame();
virtual void endFrame();
/**
* @fn virtual void TouchGFXHAL::flushFrameBuffer();
*
* @brief This function is called whenever the framework has performed a complete draw.

*/
virtual void flushFrameBuffer()
{
TouchGFXGeneratedHAL::flushFrameBuffer();
}

And the exactly error codes is here:
TouchGFXHAL.cpp:156:6: error: no declaration matches 'void TouchGFXHAL::endFrame()'
TouchGFXHAL.cpp:151:6: error: no declaration matches 'bool TouchGFXHAL::beginFrame()'
error: no declaration matches 'bool TouchGFXHAL::blockCopy(void*, const void*, uint32_t)'.
