SPI TMS320F240 bit stream length
Im using a the SPI of the TMS320F240 as slave. I use it as slave and i would like to read the bit stream that a external Master sends to the TMS320F240
As a Test Pattern, the external Master sends 0x123456789ABCDEF. This is a bit stream of 60Bits (15 Bytes7.5 Bytes), at 1.14MBitps, After each bit stream there is a small Pause of ca 9microseconds.
The bit stream, looks like this (with zoom for each 12 Bites):
Should it be a problem for the SPI TMS320F240 to read this stream, as it is an 8 Bit Peripheral? Is it possible to receive this string? and then with software distribute in 8 Bit Variables?
Thank you for your Help!
There aren't many people who are still familiar with this device as it is very old and is being discontinued.
I am very familiar with our SPI which followed this one. Based on that, I would not expect there to be any problems. My thought is you would just have to read the data after each 8 bits to prevent it from being lost. However, I do not have any experience with this peripheral. I would recommend giving it a try as this will probably be faster than waiting on an answer from us.
If you haven't looked at this already, I would recommend checking out the documentation we have available for the F240 SPI:
