Note
- This sample can be used only for the board with busmaster transfer function.
- "Overrun Error!" may be displayed in transferring.
The
driver software recognized the status of overwrite buffer when occurring
"the specified number transfer completion" event.
It immediately stops to write data to csv file anymore after "Overrun
Error!" message.
Because these data in buffer are already over-written by invalid
data.
- Data transfer
is still continuing even though "Overrun Error" is displayed.
Please click "Stop" button if you want to stop transferring.
- The root cause of ""Overrun Error!"" may set the faster clock speed on your PC's performance.
Please
try to set the slower internal clock before you click "Start"
button, again.
Or please slow down your external clock speed in the case of referring
the external clock circuit.
