DPRAM software interface to LPC2294
2006-03-17 by connor_i
Novice ARM7 developer seeks help/example code for interfacing 2 16 bit DPRAMs to LPC2294. 1 DPRAM is in read mode and other DPRAM is in write mode. Both DPRAMs left side interface to my processor, and right sides interface to another ARM processor. Dual 1-of-4 Decoder/Demultiplexer converts CS2, A14, and A15 from LPC2294 into separate CE and SEM signals for each DPRAMs. Hardware design provides for passing of common data between both processors. Application notes for DPRAM aren't helping. Not sure whether LPC's EMC is applicable to this design. Any suggestions welcomed.
