minIMu9v2 problem |
Posted: Tue Mar 05, 2013 10:09 pm |

My sensor is minIMU9v2 from pololu, the link is:
[ http://www.pololu.com/catalog/product/1268 ]
I have written code to read accelerometer values from the three sensor with in it, but im not getting anything, someone do the changes to read the sensor values.. this code i have edited from other sensor code, the link for orginal code from wich i edited was:
[ http://rigodenshi.blogspot.in/2010/10/accelerometer-lis3lv02dl-controlled-by.html ], which will print result in pc, but i need to print it in lcd.
my code is:

Obvious glaring problem. How big is an 'int' in CCS?.

Also...
according to the datasheet, the device is not I2C FAST rated...so I'd be testing at the SLOW rate(100KHz).
And...
make it easier for us to read...get rid of any commented out code

this code does not giving any output in lcd. tell me how to use the registers in the datasheet to make the the sensor work.. also tell me how you are identifying about fast or slow in data sheet.. |

LSM303DLHC datasheet, page 1 wrote: | LSM303DLHC includes an I2C serial bus interface that supports standard and fast mode 100 kHz and 400kHz. |
L3GD20 datasheet, page 22 wrote: | The I2C interface is compliant with fast mode (400 kHz) I2C standards as well as with normal mode. |
Code: | i2c_write(0x40); //01000001 --> 2g, no update between readings,12bits right justified | 0x40 != 01000001 This kind of discrepancy between comments and actual code always gives me a very bad feeling. It is a bug, but is the code wrong or only a textual error?
With a quick glance I spotted at least one other line with the same error type.
Quote: | this code does not giving any output in lcd. | Have you ever managed to get any output to the LCD? First make sure a simple "hello world" program works before expanding your project to include the more complex parts.
It seems to me like you have received enough tips to create a new version of your program. Incorporate all these changes and tips, then post your new version. |

yes i have got output in lcd, but i dont know how to proceed with this sensor. any one kindly help me to use the register from the datasheet also tell me what data i should write in that register in order to read sensor values..

Hello, have your read the examples? they have them for arduino, you might be able to use that code to help build your own?
Quote: | The Pololu MinIMU-9 v2 is a compact (0.8″ × 0.5″) board that combines ST’s L3GD20 3-axis gyroscope and LSM303DLHC 3-axis accelerometer and 3-axis magnetometer to form an inertial measurement unit (IMU); we therefore recommend careful reading of the L3GD20 datasheet (2MB pdf) and the LSM303DLHC datasheet (629k pdf) before using this product. |
http://www.pololu.com/catalog/product/1268
Maybe re-read the data sheet again. Also, I find it helpful to add debugging code into my programs. You can add a code in your Main; before the while loop, that displays "hello World" (I use a scrolling message and call it a boot screen).
And if your displaying info on an LCD, you dont want to just display the info, give it a label that prints on the LCD.
Code: | lcd_init();
lcd_gotoxy(1,1);
printf(lcd_putc,"Obj:%ld",comp); |
Doing these things will help you identify where the problem is in your code. If you see the label "Obj:" but no data, then check out your I2C code.
What value pull-up resistors are you using on your I2C BUS? Have you scoped the data line and verified data transfer? |

Code: | lcd_gotoxy(2,2);
printf( LCD_PUTC, X_out " %g=%u ", X_out); //display //send results over RS232
printf(LCD_PUTC, Y_out " %g =%u", Y_out); //display
printf(LCD_PUTC, Z_out "%g=%u \n \r", Z_out); //display |
I think you need to rework your LCD coding .. Im thinking your not seeing anything, not even an = symbol? |

I don't know what your trying to display on your LCD but I think you need a 4x20. You have 4 prints to the LCD but you never defined where the cursor starts, If I needed to display all the info at one time, I would go with a 4x20 and do something like this:
Code: |
lcd_init();
lcd_gotoxy(1,1);
printf(lcd_putc," acc:");
lcd_gotoxy(1,2);
printf(lcd_putc,"%g=%u ", X_out);
lcd_gotoxy(1,3);
printf(lcd_putc,"%g =%u", Y_out);
lcd_gotoxy(1,4);
printf(lcd_putc,"%g=%u", Z_out); |
Otherwise, display the value you need, then clear your LCD and display another value, clear the LCD and display another value.. etc. |

Don't know how this relates to the earlier code, but some comments:
What on earth are you doing with an SSP_ISR present. Get rid of it. You only ever (really) use the ISR on a slave device.
Also Get rid of:
Code: |
setup_spi(SPI_SS_DISABLED);
enable_interrupts(INT_SSP);
enable_interrupts(GLOBAL);
|
The SSP is the _same_ peripheral as the I2C (assuming you are using hardware I2C). You are fiddling with it's settings, from those generated by the compiler from the I2C lines. Not surprising it wouldn't then work....
Then if you were using an interrupt, the #INT_SSP line must be the line immediately above the interrupt handler declaration.
Then, assuming you are using the 4550 as listed in the earlier post. does C3 exist?.
Then is HS the correct oscillator fuse for 4MHz?. It _may_ work, but may not.

The code is posted by user 'vrs' without any comments. Is 'vrs' the same person as the original poster or is this posted as a 'working code' example to help the original poster?
As pointed out by Ttelmah there is a huge problem with the SSP so I doubt it was meant as a 'working code'.
Also there is: Quote: | i2c_start();i2c_write(gyro_ADD_R);gyroX=i2c_read();gyroX=i2c_read(0);i2c_stop();
...
i2c_start();i2c_write(gyro_ADD_R);gyroY=i2c_read();i2c_read(0);i2c_stop();
...
i2c_start();i2c_write(gyro_ADD_R);gyroZ=i2c_read();i2c_read(0);i2c_stop(); | The code shown in bold breaks a pattern seen in the other lines. I doubt that line is giving the result as intended. |

I do not know English.. I am writing the message using Google Translate.
Using 16F877.
codes are added for illustration.
There are many error codes, reading the wrong value
To read the value from minimu9v2 but.
working.
To Rajm example.
(gyro, acce, temp, magn) will add the complete code for correcting errors.
normally I use pic basic. |
