Source code? Rx is set by PWR_UP bit high, PRIM_RX bit high, and CE high. Tx is set with PWR_UP bit high, PRIM_RX bit low, and CE pulsed high for more than 10us - as long as there is a packet in the TX FIFO. This is just bit twiddling.
but like that i don't need initialization the C8051F120DK for its SPI peripheral. Okok sorry for so longwinded if like how i going to set what you said as i never really ever used or learnt both the C8051F120DK and nRF24L01 as the more i read about them the more i getting confused.
You seem to be between a rock and a hard place. None of us have any experience with that setup either so I guess you're just going to have to buckle down and figure this stuff out. I don't know what you expect us to do for you.
Nobody said it was annoying. We just don't have any familiarity with the setup. The documentation is inadequate to answer your problem. I'm at a loss to figure out how the people who make this stuff expect people to deal with it. That's not your fault. You may have purchased pieces that are beyond your ability to use. It happens.
