control
STM32479I-EVAL evaluation board supports both asynchronous and synchronous three-
phase brushless motor control via a 34 pins connector CN1, which provides all required
control and feedback signals to and from motor power-driving board.
Available signals on this connector includes emergency stop, motor speed, 3-phase motor
current, bus voltage, heatsink temperature coming from the motor driving board and 6
channels of PWM control signal going to the motor driving circuit.
Some settings are needed for motor control application to disconnect peripherals which
share I/Os with motor control connector and connect these I/Os to motor control connector:
Open SB31, SB39, SB40, SB44, SB45, SB48, SB53, SB54, SB55, SB62, SB65, SB67,
SB71, SB73, SB77, SB80, SB81, remove R233, R242, no jumper on JP5 (Pin2-3), no
jumper on JP9, no jumper on JP18 (Pin2-3), CN4 and CN13 unconnected.
Close SB33, SB41, SB42, SB43, SB46, SB49, SB52, SB58, SB59, SB60, SB61, SB64,
SB66, SB68, SB69, SB75, SB78, SB82. Mount R15 with 0 ohm resistor.
PA4 and P45 can be used by motor control application to output analog signals using DAC
function, in such case remove camera daughterboard from CN4, open JP3 and remove
R113.
Figure 5
and
Figure 6
show that all solder bridges and resistors to be removed are marked
in red, while solder bridges to be closed are marked in green.
