Title: DB LTC6811 with Arduino Uno
Post by: lorenrus on January 21, 2021, 02:30:34 pm

Hi everyone

I'm trying to communicate with the LTC6811 demo board.

I connected directly from the Arduino pins to the J2 connector on the demo board.

Arduino        -      LTC J2

D13 (SCK)     -      SCK
D12 (MISO)  -      SDO       (pull up with 5k)
D11 (MOSI)  -      SDI
D10 (CS)      -       CSB

Also I put the jumpers JP2, JP1, JP3 in the zero position, because I want to use the 4-wire SPI.

I monitored the MOSI line with the oscilloscope but I am not receiving anything.

I always get back that there is a problem with the PEC.

Can you help me ?

Thank you
