Part Number: DRV8704EVM Other Parts Discussed in Thread: MSP430F5529 , , MSP-EXP430G2ET Hello,
In a previous thread the MSP-EXP430GSET was suggested for use with the DRV8704EVM. I came across the MSP430F5529 which also has the launchpad headers, will this…
Part Number: DRV8704EVM Hello,
I am looking at EVAL board for my development, but I have a few questions.
1. The board two PWM generator's. I assume there a individual controlled by the on board POTs. Is there a configuration to drive both motor outputs…
Part Number: DRV8704EVM Hello,
When testing out the board Q7 and Q5 are now shorted. I was initially having issues in the PWM slow decay mode, the fault LED light up. I believe forward and reverse had the same outcome. Note I was spinning the pot pretty fast…

Part Number: DRV8704 Hello,
The status register is always showing 0x0020 when reading even though the voltage is higher than 10 volts.I am hoping if you have known issues.
As far as the other register I get the correct values.
Any suggestions?
Thanks…
Hi Mikias,
The best approach when dealing with the reserved bits is to read them, and use the default values when writing to the registers.
Writing a 1'b0 in each reserved location will also work.
For example reg CTRL ==> 0x0, has bits 7-1 reserved…
