Hi,
I am total beginner for USB interfacing.
My first project is to read data from RX buffer and store in the memory in the program.
I am using FTDi2232C chip and some EEPROM to change mode.
Currently, I am using 245FIFO mode.
It seems like the data is written to the RX buffer and I am able to read it but I can
guarantee that this data is not loss less data.
There is 384Byte RX buffer in the FTDI2232C chip.
If we put the data from input(D0 ~D7) then does data store in this 384 Byte Buffer?
If so, then is "read_ftdi" function that ftdi provides are the correct function that can read data from this buffer?
Finally, what if this RX buffer is full?, Does the data overwrite?
Sorry for many questions. Please help me.
