Now I'm trying to connection DC1894B to my MCU board using 4-wired SPI communication.
GND to GND
MISO to MISO
MOSI to MOSI
SCLK to SCLK
CS to CS
and set the jumpers on DC1894B to 0.
But when I send commands to the board,
What I got is the only 0xFF...
I saw some post that explained 5k ohm should be set between Vcc and MISO line.
I did so.
But still what I got is 0xFF,,
Should I do more connections using jumpers??
Please help me!
