OpenRTK330/OpenIMU EVK?

@Ahmed-Mohamed Hi Ahmed,

  1. we do not have a PIN for event mark. Inside the module, the GNSS chipset outputs its 1PPS signal for external device time sync. Also, the IMU data inside the module is time stamped by GNSS time.
  2. The module have L1, L2 and L5 capability, however, can only do two freqeuncies on one configuration, we can do L1/L2 and L1/L5 configurations using different GNSS chipset firmware that can be provided to you.

Thanks for clarifying.
Can a GPIO pin used to represent event mark? will there be a command to poll GNSS time when the specific pin goes high or low?

Hi, I have a problem: Acceinna extension of vscode, cannot import the project when custom imu example, the error message is as follows: can i solve this problem?

@Ahmed-Mohamed OpenRTK330 currently do not support that. What specific application you are referrering to?

@Swingw We had similar warning message, but still succeeded in importing project, and the issue seems a PlatformIO issue.

@dw-gnss-aceinna yes, even if an error is reported when importing a project, a corresponding file is still generated, but I still get an error when I want to build the firmware.

Hi,I encountered a problem:Openrtk330 cannot display data on OpenRTK Monitor,Details:

Hi, Swingw:

Has your issue fixed?

Here my issue is similar to yours: After I upgraded the GNSS_RTK_SDK firmware, our OpenRTK330LI is not able to display both GPS and IMU data (actually, both Yellow and Green LEDs do not flash).

Thank you


I now want to use openrtk330Li to output IMU raw data binary format files. In IMU examples (OPENRTK330Li / RAWDATA) provided by vscode-Aceinna's OpenIMU Platforms, what code should I modify to achieve my needs?
