#142029 - you should do what you want to do Responding to: ???'s previous message |
but I have the freedom to use any I/O. I never used the HW SPI and I really see no reason why I should use it. In most cases (of course it depends on the used devices) like an ADC, ENC, I2C etc. it is nonsens to use the SPI interface. Most of the time you have to create your own timing.
Show me how to use the HW SPI in case of the ENC, you have DIN, DOUT, CLK ;-)) is there any way to have 3 PINs at the SPI interface? Think twice and then give your comment. |
