| Post subject: | Parallel data receiving |
Hello all! I have device that transfers data in parallel mode. It has 8 lines for data and 1 clock line. Transfer rate is about 10 MHz. So I need to receive this transfer in lets say "slave mode" by my Olimex SAM9-L9260 board. I've tried to use interrupt handler to catch each falling slope of clock line, but it seems that interrupt is too slow under OS. Is there any hardware feature to receive data in such case? Or any other suggestions? Thank for all replies. Vadim. p.s. It's ok to miss first several byte of transfer session. |
