Examples project with STM32 and Spartan III?

[ygor1]

Hello ,
I need to connect the ARM STM32F2 with array of fast counters.
Counters will put into FPGA Spartan III.
Looking for a sample project in which it was joined by ARM and FPGA, your advice ?
I am particularly concerned about the interface between MCU and FPGA, do not go for anything fast, quietly serial.

I have something in the queue that's similar enough. STM32 with spartan-6.

For fast data transfer you can use a fifo on the fpga side, and dma with fifo on the STM32 side. And if you settle for a slower datarate you can use SPI.

About a sample project or appnote you do not know?

Mmmh? Should be simple enough. Grab some of the STM32F4 discovery board sample code for examples of DMA. And for the fpga side a fifo is simply pointey clickey in core generator. After that it is Just Add Work [tm].
