Greatings! I`m using DRV8711 for very first time! I`ve powered the driver with 12V and I`m using dsPIC30F5015(5Vcc) as a microcontroller. Reset pin is connected to GND and SLEEPn to Vcc(5V) as the datasheet says. SDATI of the driver is connected to SDO of the controller. SDATO->SDI, SCLK->CLK. I have pull-ups on all pins. I also tried to change the pins - SDATI->SDI and SDATO->SDO. I`m using SCS active high state and I`m dropping it low after every 16 bit transfer for about 1ms. My transfer speed is 125k. I`ve tried different commands to read a register -> 0x0080, 0x8000, 0x0008. I`m certain my SPI is working corretly.
The problem is I don`t have any activity on the SDI line - it stays high without any change... Nothing comes there...
Can you tell me what to do? Where is the problem?
Thanks!
