IMU383ZA-400, Timer field in S1 Packet always zero

diz4 — Mon, 14 Oct 2024 16:23:54 GMT

Dear сolleagues, i parse S1 packets from IMU383ZA-400 (via UART). Manual says that S1 packet has a field called "timer" (with offset 20), and user could use it for synchronization purposes or delta_t computations, but it's always zero along with BITstatus word. I checked CRC and rest of the data , all ok. Seems like IMU doesn't provide those fields. Could you help me please, what should i do , to include at least Timer information into the packet? Firmware upgrade or some settings? Thank you.

imu383 support 1pps and 1khz pulse synchronization, but not support ZDA and other NMEA TEXT msg.
只支持1pps和1khz同步，不支持ZDA等NMEA TEXT 消息。

The relevant parameters of IMU383 are not mentioned in the manual

IMU383 serial port configuration

TJyjygood — Mon, 08 Mar 2021 07:51:15 GMT

According to the serial port configuration part of the manual, I can receive the s0 packet by sending "S0" through the serial port, and sending 0x02 can adjust the packet rate of imu from the default 100hz to 50hz, but now I send the command through the serial port, imu It hasn't changed, what's the matter? Or do you have a serial port configuration example for imu, can you give me a reference?

HI is there a way to provide external Power to the EVK and disconnect the power from the USB?

IMU383 SERIES USER MANUAL

TJyjy — Wed, 23 Sep 2020 06:57:13 GMT

@cek I only use the burst mode to read, but the data is incorrect. My imu383 is on the table and does not move, but the data display is not close to zero. But when I only read in polling mode, the data is correct. Did I overlook something?

Not able to configure UART a2 message for AHRS

Frederico — Tue, 22 Sep 2020 23:37:43 GMT

I have the DMU381ZA unit with the SDK. I uploaded the original VG_AHRS (for DMU381ZI, no DMU381ZA available) firmware using VS Code. The unit connected to the Navigation Suite and I could see the acceleration, gyro and heading charts correctly. I installed the unit in my application with pin 7 grounded but still can't see a consistent UART message through pin 3 with the two starting bytes (0x5555). Initially I got some serial output without any 0x5555. I uploaded and tried using the compass app and got no serial output in pin 3. I tried another unit with the original INS app and again, got output only when using Navigation Suite but no UART output in pin 3. Am I missing something in the configuration process?

280ZA-209 Datasheet

Florenc Caminade — Tue, 04 Jun 2019 12:29:50 GMT

After reading deeper I am not sure that the 380ZA is the same as the 280ZA because there are some missing information / differences with the 280ZA : Accelerometer and gyro scales, registers adress... for example 0x70 was the adress of acceleration scale factor but for the 380ZA this adress is reserved (For chance I had saved some data in my code) .
Now I want to set up the "external System Clock" but I suppose the adress is different on my 280ZA. So for me this user manual is not the right, say me if I am wrong...

[imu381]The data sample delay with IMU381 Low-Pass filter settings

Li YiFan — Thu, 31 Jan 2019 08:38:21 GMT

user could change Low-Pass filter bandwidth in register 0x38. If the filter is switch on, there will be several microseconds delay with IMU data sample.
