Hi Luis:
These are the various measurements I got on the new circuit:
Sense Resistor
SRC34 - 0.83 Amps; 5V (across 2 ohm resistor)
SRC12 - 0.0 Amps; 0V (across 2 ohm resistor)
Load
OUT1 - OUT4 : 0.86 Amps and 5V (upto varies below based on type of stepping)
OUT2 - OUT3 : 0.86 Amps and 5V (upto varies below based on type of stepping)
The fault line input comes as HIGH while using a input pull-up resistor. But I still have no movement on the motor even though it continues to make noises and the chip also heats. Using 100uF charge pump and 10uF discharge capacitor as hinted in the data sheet.
So please any suggestions to get the stepper moving.
