Hi,

How to use setUserMagAlignParams() ? how to calibrate magnetometer manually and compute hardIron_X , hardIron_Y , softIron_Ratio and softIron_Angle to use with setUserMagAlignParams()? what is your calibration algorithm? please give me an article about your calibration method. the source code of ProcessMagAlignCmds is not available, can you please show me the source code of ProcessMagAlignCmds function?

I was sent start mag align with autoend command to the sensor, I then rotate the sensor in z axis more than 720 degrees, I can confirm that its working but the accept and save to eeprom command is not working. after sending accept and save to eeprom command ( 55 55 6D 61 01 05 A1 8B – Accept Mag-Align Results (write to eeprom) ) it will not save to eeprom, after restart it will start with default values.

please help me to calibrate my openIMU300ZI.

Regards,
Amin.

Hi,

I have to calibrate my openIMU300ZI sensor follow the instructions, I have sent Start Mag - Align with auto end command ( byte array 55 55 6D 61 01 01 E1 0F ) to the sensor via user port on baud rate 115200 , but there are no responses on debug port, I have changed debug port's baud rate to 115200 and already tested on baud rate of 230400 with no success. I was add a Hello world message using DebugPrintString((char*)"HelloWorld\r\n"); in main.c just after DebugInterfaceInit(); and before osKernelStart(); to make sure the debug port is okay and working, I can see the HelloWorld message on my debug port.

I have sent byte array from a simple program written in Delphi by myself.

The application is VG-AHRS and version is 200211-193813-VG_AHRS.

do I need to change anything to be able to calibrate magnetometers?

Hi, thank you for reply.
Do I need to pullup spi pins with 10k resistors? ( miso , mosi , clk , nss)

Hi,

I have to read data from my openIMU300ZI sensor through SPI connection, I have set up connections with correct wiring, SPI mode 3, with clock frequency 1Mhz.

I have a question about Data ready pin, is it only for selecting UART or SPI peripheral or it can be use as real data ready signal to tel master MCU there are data available to read? ( in burst mode 0x3E00 )

I planned to implement external interrupt on my master MCU and connect Data Ready pin to that, so by this way I can read data when ready to read. am I right or I am misunderstood ?

Please explain the correct way to read data in burst mode on SPI.

Amin.

Hello, I'm waiting your answer, I need to calibrating heading for my project.

Best regards
Amin

the code is 20011-193813-VG_AHRS I did not updated it recently.

the only change to the original code was:

in main.c file

and a hello world message in main.c file before freertos kernel start

// Apply factory configuration
platformInitConfigureUnit(); 

// Apply user-chosen configuration
userInitConfigureUnit(); 

// Initialize OS and create required tasks
CreateTasks();

// Initialize the DEBUG serial port
DebugInterfaceInit();
DebugPrintString((char*)"HelloWorld\r\n"); // <----- here is a hello world message on debug port, but nothing shows up on debug port

//InitTimer_Watchdog( ENABLE );

// Start Running the tasks...
 // Start scheduler

osKernelStart();

void DebugInterfaceInit(void)
{
char status[100];

if(fSPI && fGPS){
    return;         // no resources 
}

int debugChannel = platformGetSerialChannel(DEBUG_SERIAL_PORT);

if(debugChannel == UART_CHANNEL_NONE){
    //nothing to do
    return;
}

// Initialize the DEBUG USART (serial) port
InitDebugSerialCommunication(230400); // debug_usart.c // <---- I was changed the baudrate of debug port to 115200 here
DebugPrintString((char*)"from debug port\r\n");

BoardGetResetStatus(status, sizeof(status));

// ERROR_STRING(status);
}

I was sent 0x55 0x55 0x6D 0x61 0x01 0x07 0x81 0xC9 bytes on user port ( the port that receiving output data through that ), I expected to receive some information on the debug port, but nothing. I am sure that its not wiring problem.
I'm using this pins ( 17 , 19 )

Dear friends,

I have a problem on my openimu300zi , there is no output on debug port at 230400bps baudrate , I have changed the debug port's baudrate to 115200bps in source code too but no difference.

Do I need to enable debug outputs in source code or its already enabled, I have to calibrate my magnet but there is no output on debug port.

Please let me know if I need to do anything in the source code.
I am using vg/ahrs app.

Regards,
Amin.

Hi,

I need to increase the accuracy of HEADING on my system, I am using openIMU300ZI, may I use an external magnetometer sensor such as RM3100 or HMC2003??? openIMU's output is attitude, I want to use an external magnetometer sensor separately with openIMU on my system to combine calibrated magnetometer's data with openIMU's quaternion (VG mode). could you please advise an algorithm to combine these data together, or at least an article.

Best regards,
Amin.

Hi,

Thanks for the reply, I am trying to learn extended kalman filter using your library, currently I am using your ahrs app on my openimu module.

Dear support team,

Can you please let me know what is the external crystal connected to stm32f405? The frequency please?

Best regards,
Amin.
