| Hi,
How to connect a PIC (Master) to 70 PIC (Slaves) in SPI? I wonder, a direct connection of SDO, SDI, SS and SCLK between a master and multi-slaves will work? especially the SCLK, do we need buff ... |

| When I change to PIC18F, it works just fine. With the same code and slight changes on the fuses, its simply not working with dsPIC.
Help needed please. |

| I changed to PIC18F13K22 and use the internal 64MHZ frc. However, the delay_us(100) can only reduced to 26us. If I reduced to 25us, the adc result passed to master will be incorrect. So, I guess the d ... | |

| Yes. this program works well. thanks PCM Programmer.
if i were to read continuous ADC from slave and pass to master, is there a faster way (because we have to provide delay_us(100); // Give slave ... |
