Hi! I am programming for the nRF24L01+ module but it seems do no work. I cannot receive data via wireless communication and when I read the registers I wrote, I cannot receive correct reply. I think there may be some mistakes for my programming. I have four questions for that:
1 I use eZdsp F2812 to control the nRF24L01+ module. It has GPIOs working as SPI pins, and I successd when I contect two DSP board for SPI communication. Can I just directly contect four pins in the module to the four SPI pins in the DSP?(MISO-SPIMISO; MOSI-SPIMOSI; SCK-SPICLKA; CSN-SPISTEA)
2 I notice that in the code example, it uses “unsigned char” for the transmission, but I use “unsigned int”. Is that necessary for me to change it to unsigned char?
3 Is there any requirement for character length in nRF24L01+ ? How about 16 bit?
4 I read the nRF24L01 datasheet for my programming. Is there any difference betweem nRF24L01 and nRF24L01+ ??
Thanks a lot!
