I can get tele_powerbox and lipomon_14 data from an Arduino to my Airware 1.11 DX9.
Note that the endianness of the data for tele_powerbox is opposite to that of an Atmega Arduino (and 6S tele_lipomon). Steve |

Hello Andy,
I know that. My Issue is that the tm1000 does not recognize my request for powerbox. I did what Steve suggested, let the dx9 run the autoconfig but the powerbox is not recognized. For eg. Vario or fuel gauge it works. What is the H file in GitHub? Thanks for your support. Paul |

You need to reply properly during enumeration. If you give an invalid response, the tm1000 will not poll you.
I'm on my phone so a link is tough. You can find it in the AR4649T thread in Radios. Miguel posted it. There's other helpful stuff on the GitHub page too. Andy |

Hi there, I'm back at working on my telemetry sensors.
What I have found is that there is a huge difference on the internal I2C termination resistors on TM1000 and the AR12300T receiver. I connected the lines to GND and measured the current: TM1000 pull-ups: 3.3V, 329ľA = 10k AR12300T pull-ups: 3.3V, 3mA = 1,1k I also found that when using PIC12F1840 or similar (I'm using PIC16F1825 now, it has more RAM), the I2C just don't work right when running the MCU from the 32MHz internal osc, it needs to run at 16MHz in my case. I haven't tried using other types of oscillator. |

Arduino sketch
This is an awesome thread - I've read all 552 entries and found lots of great code for multiple slaves/multi registers on a single arduino, but i'm still at the entry level trying to program my first pro-mini to give me amperage on my DX8 gen 1 (and maybe some nav lights just for fun).
my (simple) plan was to use an ACS758LCB-050B hall sensor analog output to a pro-mini and I2C relay that on address 0x03 to my TM1000. I'm looking for something to measure around 12 amps on a Trex 450. I'm a veteran basic coder, but new to C and am having a devil of a time with the syntax for getting an Arduino to talk to a TM1000 (I am thinking of ending all my sentences with semicolons. That's progress, right?). does anyone have a simple arduino sketch for single pro-mini slave using analog input and I2C output to a TM1000 that I could use as a starting point? |
