if possible, could you share with me your SPI drive codes?
pls try the sequence in below when start SPI mode communication(confirm 1&2 pins in P1 area are not connected):
- start the SPI read program in your Master MCU.
- Power on 330BI
- update FW to FW2.1 in https://developers.aceinna.com/code/apps
- try other register, such as:
or try burst read 0x3E
for 300RI is same connector with MTLT305D, so pls refer to one topic below:
you need converter of RS232 and usb, 4.9-32V is ok for 300RI.
hi, Amin. working well in my side, and my steps:
- download codes VG_AHRS 1.1.3 from VSCODE
2.update codes and keep same with you.
- compile the new BIN and uploaded it to 300ZI.
- keep EVK board connected with PC, 4 ports detected in pc, like: com51/52/53/54
- connected COM52 with 230400 by serial tool uart-assistant, and open the port, waiting
- keep power on EVK board.
- take off(disconnect) 300RI and connect 300RI to EVK board again, uart-assistant will receive
"from debug port
