I will upload my project in the next post but it's giving me a problem in that code that works in main.c doesn't work in isr_1.c, specifically the code starting at line 198 in main.c
response = LIS3DH_GetAccAxesRaw(&data); // TM read and print Raw Accel data
//print data values
sprintf(strMsg1, "Xx=%6d Yy=%6d Zz=%6d \r\n", (data.AXIS_X >> 6), (data.AXIS_Y >> 6), (data.AXIS_Z >> 6) );
sprintf(strMsg1, "X=%6d Y=%6d Z=%6d \r\n", (rawAccel), (rawAccel), (rawAccel));
Works with data read out like Xx= -12 Yy= 7 Zz= 244
but the same code at ine 185 in isr_1.c is supposed to populate the array variable rawAccel..
response = LIS3DH_GetAccAxesRaw(&data); // TM read and store Raw Accel data
rawAccel = data.AXIS_X;
rawAccel = data.AXIS_Y;
rawAccel = data.AXIS_Z;
which is supposed to be printed out by line 204 (the last line in the code above) but it doesn't produce any data, the printed line is always all zeros. The raw accelerometer data is supposed to be 12 bits left justified stored in a int16. I've proved that, in the ISR code, I'm getting a 1 for the response because LED2 lights up. This may be the way I'm trying to share variables across all the files.
I'd appreciate any guidance you guys may have.
