#158600 - SPI slave |
hi to all
Im thinking of making a SPI slave or I2C.. first question is which better? and why? next is..im using 2051 MCU, and i want it to be as a SLAVE..could it be done? lets say SPI, will i put my MISO on interrupt or polling? like when you use a ISP programmer, you just send routine on CLK and MISO, then you will have and output on MOSI. uhmm did i get it right? or i mix-up MOSI from MOSI? anyway help me pls :D |

| UART! | 01/01/70 00:00 | |
| Not complex - just requiring low baudrate | 01/01/70 00:00 | |
| kind of rcorrect | 01/01/70 00:00 | |
| Complexity contra recommendable | 01/01/70 00:00 | |
