Hi, anybody out there done an SPI interface between several 8051s?
- Do I need to provide HW (jumper select MOSI and MISO) type of things to make one 8051 the master and the rest of the 8051s slaves
or
- Does the dedicated SPI HW and internal 8051 resources allow for MOSI and MISO to mux serial in and out so I don't need to have jumpers.
I am using Silabs 8051F60s and 8051F20s that have dedicated SPI resources. Silabs tech support and examples are very good but I thought I would post here also as you guys have always been a great about sharing experiences that both clear my head and expand my mind. ;-)
Thanks much, Ed V.
PS - I did read the data sheets and give this some thought but am still a little cloudy. I am inclined to think "2." is right but like I said its a little cloudy in Ed's head today.
