I am planning to use the FPGA as a coprocessor to the DSP.
I was thinking about connecting a dsp (like the blackfin bf533) to an FPGA (like cyclone iv) via two ppi interface and spi. One of the ppi would be used for input, the other for output. The spi would be used for commands.
Can i connect...
I'll connect the ground together. I wont touch the voltage lines.
I'll connect the rx and tx to the corresponding pins on the microcontroller.
In certain circumstances i will use a buffer.
Its the same with the FPGA? Does it matter that they have different power supplies? How much load will the...
Hello,
Say i have a device that has:
output voltage (say 3.3)
ground
tx output
and rx input.
How would i connect it to a FPGA?
Precisely, how do i
1)input external ground (of the device) to a FPGA so that it (the FPGA) can measure the voltage on the pin that is connected to the tx pin of the...
