Hiya Kerry
Thank you so much for your reply. I have included the code for the onBusStartDetected event, as this is the only one that is hit by the code at the moment. The code is basically just for tracking repeated starts. In the scope trace, you can see that the bus freezes after the r/w bit. In the debug window, you can see that the 7 bit address is 0x54. I tried to pick some other useful registers to show - it looks like the bus is busy but the peripheral knows it isn't being addressed...
void SlaveI2C_OnBusStartDetected(LDD_TUserData *UserDataPtr)
{
/* Write your code here ... */
SlaveI2CUserData * SlaveI2cUserData = (SlaveI2CUserData *)UserDataPtr;
MSG("Start!\n");
// If the start flag is TRUE, there has been a start before this start, but not a stop.
// This means there has been a repeated start. We only want to handle repeated starts
// after a write operation.
if (SlaveI2cUserData->_gStart && SlaveI2cUserData->_gWriteRequest)
{
SlaveI2cUserData->_gRepeatedStart = TRUE;
SlaveI2cUserData->_gOffset = SlaveI2cUserData->_gBuffer[0];
// The peripheral is expecting more data, so cancel reception of the rest of the
// data
SlaveI2C_SlaveCancelReceptionBlock(SlaveI2cUserData->deviceData);
// The only possible operation after a repeated start is a read
SlaveI2cUserData->_gWriteRequest = FALSE;
}
else
{
SlaveI2cUserData->_gStart = TRUE;
}
}
