OpenFormMZ板上MRF24WG0MA的SPI速度

[Tomson]

Hello dear digilent engineers！

       This WIFI connection module of MRF24WG0MA is very cool.I want to know the real-time SPI speed  of MRF24WG0MA on OpenScopeMZ board actually. Reached 20Mbps ?

Hey,

I need to confirm with Keith, but I think the SPI bus between the PIC and the MRF is clocked at 25 MHz.  However, this is not a good indication of the actual Wifi throughput.  There are other potential bottle necks, like the SD card, CPU memory copies between the sample data buffers and the networks stack buffers, etc.  We typically get about 100 KBps actual throughput from the OpenScope MZ  to WaveForms Live.
