      Buzby replied to the thread INA228 power measurement.
      There's no PICAXE code needed for calibration. The chip just needs SHUNT_CAL loading with the result from a rather messy calculation. I...

      It's even easier than that, there is no conversion needed if you just use 16 bits. Chip holds a 20 bit value in 3 bytes, with 4 unused...

      I got some success ! First challenge, finding the resistance of the shunt. The MATEKSYS website is not very useful, (...

      Not much done today, just tidied up the results a bit. I now need a way to put a few Amps through the device, without frying myself...

      I've got started reading the INA228 module. First task was to find the chip address. The screenprint says default address is '69'...

      Thanks, that's a kind offer. I'll happily try one out. Problem is, I'm on moderation, so can't send new messages. However, I can reply...

      It won't be that difficult !. Section 8.1.2 of the datasheet explains that the calibration needs to be set before most registers can be...

      When you say 'measure power', do you mean mains power ( 240v AC in UK ), or low volt battery DC ?. The datasheet...

      I'm ready to try named pipes again, but I've lost my files from 2014 ! The link : http://www.picaxe.com/docs/PE6_Named_Pipe_Plugins.pdf...

      Buzby replied to the thread Bins Alarm.
      I wouldn't trust jumping out of any subroutine if there is any possibilty of screwing the 'return' stack. Much better to re-write the...
