Other Parts Discussed in Thread: TMS320C28346
Hi!
I am using the TMS320C28346 controlcard with the DIMM168 experimenters board. I need to shift data from an external ADC (ADs1278-EVM) to a PC. The connection via SPI to the ADS works just fine, the data is shifted correctly into the TMS320C28346. The ADC is producing a data of 10MBit/s.
Since there is a FTDI chip on the base board (FT2232H) which is used for the JTAG and is able to be used in High-Speed-mode of the USB as well, I am having some questions:
1.) Can I use the FTDI to shift my data to the PC using USB? Because as far as I know the USB driver FT2232H has two USB channels on it.
2.) If so, can the data be shifted in High-Speed-mode? This is very important for my project - we need a very high sampling rate which causes the mentioned data rate.
3.) Finally, how can this be done? Is there any example code for using the FTDI chip for USB purposes?
My first idea was to use an external FTDI driver (FT232H on the UM232H) to be connected to one of the SPIs on the experimenters board. Shifting data from one SPI to the second one already works.
Thank you very much in advance,
Johannes Miersch
