hi guys! need help in our project.. we are constructing a simple device that could transmit data over short distance but with great accuracy and timing.. but we have a problem about the frequency that we are going to use.. please help us about what kind of transmitter can we use and how are we going to choose the frequency.. tnx
for replies pls email me at tebancute@yahoo.com or stephen.buslon@gmail.com
STR71x...
Use SPI. Frequency: 1 MHz. Very accurate, great timing.
Use I2C. Frequency 400 kHz. Even more accurate, loose timing.
Use USB. Frequency 12 MHz. Also accurate, great timing
Use UART. Frequency 115200 baud. Also accurate, bad timing.
Or do you need to specify your question?
I would guess that the OP actually means wireless transmission, but then again, that's just a guess.
