Notice the two printf lines. I can have both statements print
when I comment out the printf in I2C_OnMasterBlockSend this event never asserts.
the code gets stuck in the first I2C write event.
do
{
appData.Error = I2C_MasterSendBlock(appData.I2C_Ptr, &data, 1U,LDD_I2C_SEND_STOP);
while (!appData.DataTransmittedFlg){}
appData.DataTransmittedFlg = FALSE; ///CODE REMAINS HEAR.
if (appData.Error != 0)
{
printf("I2C write during read error %d\r\n", appData.Error);
//cpu_delay_ms(1);
}
} while (appData.Error != 0);
when I put it back in it works fine.
how can I remove these printf calls and still have my code work?
thanks
