• The device appears as OpenIMU300ZA, I think due the wrong EEprom image, could you supply me a correct one ?
• It is possible to restore/remake the calibration ?

Best regards

1. why did you deleted the memory of 300RI? did you met problems when connect with PC or other operations?
2. pls supply SN number of your 300RI? SN are composed by 10 figures, such as: 1908811027 in my hands.

1: yes, I did play around with the programmer, so I deleted the memory ... sorry
2: the serial number is: 1908400166

Thanks
Andi

the SN of the housing is 1908811009.

Many thanks

could you supply me please the whole bin file for the 300RI 1908811009 ?

Thanks

The Chinese AE team is on the Chinese new year holiday and will be back to work next monday. The whole bin file should be ready by then.

Thanks.

I have the same problem, I have an openIMU300ZA installed on my own designed development board, I have st-link v2 , I forgot to backup flash program from the factory , I can program the module with my built images from the source code and downloaded images from the website but I can not make it working, I have write VG/AHRS program on my module, when I connect it to the PC's serial port I can read data coming from the sensor, when I read all data in a packet from sensor , the header bytes are okay, the a2 bytes are okay and the payload length is also okay, its 48, I expected roll and pitch and yaw bytes after that starting from byte 12 as roll value, all are 0 0 192 127 0 0 192 127 0 0 192 127 , I do not know what is wrong with my module.

could you please send me the image including factory calibration information for my module? the serial number is : 1006723098

Best regards,
Amin.

the serial number is 1908400114 , its below a barcode. I have programmed the 1908811027_ 1.0.2_a2.bin into my module, and after that from the IDE programmed my own compiled VG/AHRS into my module, its seems that its working now, I have roll, pitch but not correct yaw.

please send me the image of my own module with serial number 1908400114. the whole image including calibration data.

there is another problem, WebServer_win32_1.1.1 can not detect my module.

Best Regards,
Amin.

Your module is 300ZA, pls do not use 1908811027_ 1.0.2_a2.bin which is belong to 300RI unit.
Refer to backup steps in topic_4, pls backup your current whole bin whatever it is working ok or not.
In future 2 weeks, maybe i can only working in home due to the pneumonia control, and cannot make the right bin for you which have the right calibration data.
Currently, only share with you other SN whole bin(1908400166_1.1.0.bin) by email, pls upload based on steps topic_4

1908400166_1.1.0.bin

Hi,

thanks for your replies, unfortunately I was forgot to backup whole bin file from my module, and I programmed it using st-link from starting address 0x08000000 , I think all factory calibration data has gone. so if I am right and you know that my calibration data is really erased based on my mistake and starting address I was programmed, please send me a correct bin file, the 1908400166_1.1.0.bin file is good enough for now, I was programmed that bin file related to RI series to recover data stored at starting address, and then I programmed my module from the IDE to store VG_AHRS application in correct address on my module. now its working but I am not sure with calibration data of another module how much accuracy it can have.
another question for all people like me for future mistakes: is there any way to calibrate modules by users? I know that the factory calibration is very accurate, if its possible please post your calibration method.
my email address is : amin.yarmohammadi@yahoo.com please send me 1908400166_1.1.0.bin file.

Best regards,
Amin.

Thank you very much, I appreciate your help.

Best regards,
Amin.

Cheers

109_with_VG_AHRS.bin

could you please send me the factory calibration bin file for openIMU300ZA with 1908400114 serial number?

Best regards,
Amin.

Is it possible to load these via the NAV-VIEW software?
