Hi All,
This message is about improving the data stream from radioberry to RPI and lower the utilization of the RPI CPU: also the resources required within the FPGA are really limited in comparison to a full ethernet stack!
Iam enthousiastic !
Playing with a module UM232H which uses a FT232 chip . (only one channel)
Running a program on a W10 PC
(will do the same on a RPI)
Type = 0x8
ID = 0x4036014
SN = FT58CPW2
Description = UM232H
Device with serial number found
Read 1GB from the FTDI in 26.3 seconds.
Average read speed: 326.3 Mbps.
(Running with 254 protocol)
Using only the module not yet connected to the FPGA; pretty amazing results!
I have been reading a little about these FTDI devices today; always thinking that these devices are replacement for serial communication for RS232 replacement... but it seems to be more capable!! Nice.
There are also FTDI chips implementing 2 or 4 channels ... making it possible to program the FPGA.
The only thing with the current board is how to add the module (also the numbers of IO )
But there are multiple protocols... will look into it as well and see how to make the connection!
