Hi,
I need to made data transfer between Blackfin ADSP592 and STM32F407VG processors through Parallel peripherel Interface protocol.First DSP should be in TX mode,it has to send a READY signal to F407 to start the communication.After getting ACK signal from the F407,it sends the original data.After receiving all the data,the F407 has to send a RXed signal to DSP to stop the communication process.Then DSP has to change its mode into RX,and the above process has to be reversed.So please give me some ideas how to configure the DMA,PPI ports,CLK and how to initialize the timer and interrupts?And also I need to know how to configure the FSMC and the control signals at F407 side.There should be lots of synchronization issues occured during loopback.Please help me out regarding this issue.
