Append to new file about ch376msc

Hi, yes i reproduced. Actually flashDrive.openFile(); function returns a value.If the file is not exist then return 43h what is ERR_FOUND_NAME answer from the chip. So it has to be "if condition". if(flashDrive.openFile() == ANSW_USB_INT_SUCCESS){ flashDrive.moveCursor(CURSOREND); } .Thanks, i will update the example code.

Thanks! My current workaround is openFile() then getFileSize(). If the file length is zero then I can use writeFile(), but if it's not then I use moveCursor() then writeFile().

I'm using your code for a simple data logger. I have noticed a couple of odd things, so if I can't get them working then I'll post an issue here. Thanks for taking a look at this one.
