Hello,
i`m working with a platform wich has to transmitt and receive file. Scenario is the following:
in the platform there is a micro (Blackfin DSP) and ZigBit module (atmel module with a transceiver inside): micro`s pins i used to communicate are the ones belong at SPI PORT, instead for ZIGBIT i use UART PORT, between them there is a spi/uart converter (MAX3100).
I have to transfer a file (usually the size is 100k) from my pc, where is connected an other device wich transmitts by zigbee to my platform.
During transfering the communication is stopped by micro and i can`t understand why....
the opposite transfering (micro to pc) works really well!!
I think the problem is with temporization between spi protocol and uart protocol when the file to receive is so long.....is it possible????
please, let me know some suggestions!!!
thank you to everybody!
