Hi Brandon,

Thanks for the follow up.

Looks like the original thread got closed. David is out of office and should be able to look at this by early next week once he is back.

Thanks

Hi Brandon,

I reviewed the code in the linked thread and write to address 0x09 (CONFIG0) to set EN_OUT seems to be missing. Following the below steps I was able to get the OUT1 pin to go high with OUT2 being low:

set nSLEEP pin high
write 0x7 to address 0x0D to set IN1=H, IN2=L, and set PH/EN mode
write 0xE0 to address 0x09 to enable OUTx pins

Regards,

Joshua

Thank you for the response. I have one more question. When connecting to my ESP32-S3 via I2C, are there any shunts that should be removed from P1 main signal header? I have looked for guidance in the manual but have failed to find any.

Hi Brandon,

If connecting to an external MCU, remove all jumpers that are connected to the MSP430 (as shown in red box below). The A0 & A1 signals are tied to GND to set device addresses. The DRV_3V3 is suppling VCC pin on device with 3.3V and is supplied from the USB power.

Best,

David
