Hello, We have a product developed on an Intel Atom SBC and a NI DAQ that provides 2 AO, 8 DIO and 2 counters, for laser control on real time. The system runs with a RTAI partched linux and Comedi drivers to achieve real time performance on microseconds period (25 usec). A compact flash stores all the software and data. We would like to migrate to a CPU + FPGA environment on the same card, for space and cost reduction, and future developments. I have a lot of questions related to this migration, I would really appreciate any help on this: - Is it possible to get AO on the FPGA? It could be with Pulse Width Modulation, if there is not possible to get a real AO - Could you recommend a card with a CPU and FPGA, all together, to start learning about this? - Any other hints to start on FPGA and linux on the same card? Thanks in advance Antonio López --------------------------------------- Posted through http://www.EmbeddedRelated.com
