I have already confirmed that the P/N 8350-1800-01 that I bought before has an Output Data Rate of 200Hz UART output.
The one of P/N 8350-1800-02 that I bought recently has only Output Data Rate 50Hz. (UART)
Is there a change in the default firmware that prevents the 200Hz output?
Also, I originally bought it with the expectation that it would output 200Hz, but has the specification been changed?
If you need any additional information, just ask.
The factory firmware_1.1.10 of the OpenIMU330 does not support 200hz output updates.
Please upgrade the firmware of your device by SWD interface with ST-LINK, for detail steps about the upgrade process, see the link:
https://forum.aceinna.com/topic/93/top-topics-of-common-operations-with-openimu-products.
"9. how to upgrade only new FW with ST-LINK?"
"for 330"
The attached firmware is a latest version that supports 200 Hz output, so you can try to use it .
OpenIMU330BI_FW02.01.bin
could you supply current FW version which is used in your current units?
I think the units was already mounted on your PCB, so we will prepare the UART commands for you, which can be used in your system to set output data rate 200hz via serial communication.
will send out soon.
Thank you for replying.
could you supply current FW version which is used in your current units?
I whill check the firmware version, but I don't know how to do it.
Pls teach me how to check current fw version.
could you send serial commands to 330BI in your system? take a pic of your HW will be better at same time.
You can use "pG" command "55 55 70 47 00 5D 5F" to get device serial number, firmware version and factory ID.
At the same time please follow below steps to set output data rate(ODR)200hz permanently:
"uP" command: "55 55 75 50 0C 04 00 00 00 C8 00 00 00 00 00 00 00 F0 D5" ，set ODR 200HZ.
"uP" command feedback "55 55 75 50 04 00 00 00 00 1C 26", it means operation succeeded.
"sC" command "55 55 73 43 00 C8 CB" , save the parameters.
Thank you to share "pG" command information.
I send pG command for 50Hz and 200Hz IMU.
50Hz
OpenIMU330BI 5020-1800-01 02.01 SN:2074009097
200Hz
OpenIMU330BI 5020-1800-01 02.01 SN:1974001265
Frimware version and Unit model is same, but output rate is different.
uP" command: "55 55 75 50 0C 04 00 00 00 C8 00 00 00 00 00 00 00 F0 D5" ，set ODR 200HZ.
"uP" command feedback "55 55 75 50 04 00 00 00 00 1C 26", it means operation succeeded.
"sC" command "55 55 73 43 00 C8 CB" , save the parameters.
I haven't tried these commands yet. I whill try it later.
First of all, why is the output rate different for the same FW Version?
I will check the factory Settings of these two Units, when i find the difference between both of them, I will reply you.
I have examined your questions and come to the following conclusions:
(1)The ODR in our factory Units is 50hz.
(2)The setting of Units with SN:1974001265 may have been changed.
(3)In future, the default configurations of Units are:
FW2.1, baudrate:115200, output rate:50hz, packet type: z1
