03:16 JeeLabs Café Support: Confirmed: data read during DRDY transition causes split word. Software solution: poll R...
Unfortunately, the ModernDevices board does not connect to the DRDY pin on the HMC5883 board. Fortunately, I have som...
01:45 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. My readout code unreliable?
Using the wire library, you can set the I2C clock to 400 kHz by changing one 328p register:
void setup() {

00:09 JeeLabs Café Support: HMC5883 readout high and low bytes get split across two readings?
**Ok, I think I’ve figured it out.**
But if so, either I do not understand the data sheet, or the data sheet is wron...
20:20 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. My readout code unreliable?
…nope, even with 21 - 22 msec delay between reads (less than 50 Hz output) I still see the glitch:
seconds, mX, ...
20:14 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. My readout code unreliable?
Ok, this is interesting. I thought it was working OK using hardware SDA, SCL lines. But after about 100 seconds, we g...
19:01 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. My readout code unreliable?
Thanks for the support guys! I’m pretty sure it’s my code somehow, and not the board at fault, I modified my subject ...
17:52 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. My readout timing bad?
Looks pretty clearly like it’s some timing problem in my code. I think the existing library does not touch 0x00: Conf...
01:58 JeeLabs Café Support: RE: Modern Device HMC5883 Compass Board. Unreliable?
And just to show that it isn’t just one sensor board, here is the same problem showing up later on Sensor\_2:
s...
01:46 JeeLabs Café Support: Modern Device HMC5883 Compass Board. My readout code unreliable?
**EDIT 12-Dec-2014 18:30 PST: Problem was solved. See later posts.**
I got a pair of compass boards (HMC5883) from M...
