"SSP1BUF = MRFSPIdata": This loads real fast. But the actual transmission that takes place after that, takes a lot more micro seconds.
If you write to the SSP1BUF back to back, the TX buffer gets...
Do you think it would be too risky to just assume the transmission is complete if I am only sending a byte or two?
just send using MSSP and go about your business or must I poll the flag?
do I have...
Correct on both accounts. As the SPI clock frequency goes up there's not much gain going the interrupt route so you can just as well poll the flag like that. The MSSP module CAN be a bit tricky to...
Hi,
If you have WORD sized variable and specify 12bits, MSBFIRST, one might think that it would shift out bits 15-4 but it doesn't. It shifts out bits 11-0. With LSB first it shifts out bits 0-11. ...
SHIFTOUT is a software-based command and does not require that the target device have synchronous serial capability. The ClockPin and DataPin parameters...

This is an effort to help users understand how the I2C command works by comparing it with SHIFTIN/SHIFTOUT. A serial EEPROM, 24FC1025 will be used in the example.
