control
The STM32F779I-EVAL evaluation board supports both asynchronous and synchronous
three-phase brushless motor control via a 34-pin connector CN1, which provides all
required control and feedback signals to and from the motor-power-driving board.
Available signals on this connector include emergency stop, motor speed, 3-phase motor
current, bus voltage, heatsink temperature coming from the motor driving board and six
channels of PWM control signal going to the motor driving circuit.
To enable motors control applications, some reworks are needed to disconnect the
peripherals, which share I/Os with the motor control connector, and to connect these I/Os to
the motor control connector:
•
Solder bridges to be opened:
–
SB3, SB36, SB43, SB47, SB48, SB52, SB54, SB55, SB62, SB66, SB69, SB71,
SB74, SB17, SB75, remove R93, R98, R245, R256
•
Keep no jumper on JP3/JP6/JP9/JP10/JP14
•
Keep CN4 and CN13 unconnected
•
Solder bridges to be closed:
–
SB34, SB37, SB42, SB45, SB46, SB49, SB50, SB51, SB53, SB56, SB57, SB60,
SB64, SB67, SB70, SB72, SB73, SB18
•
Mount R14 with 0 ohm resistor.
PA4 and PA5 are DAC outputs when using them for debugging purposes, keep CN4
unconnected and remove R124.
In
the components which need to be removed are marked in red,
while the ones that need to be in place are marked in green.
