Hi, Thought I would post my project here. I have been working on it for nearly 2 years. It is based on the teensy 2.0++. It is going to be sold to oilfield service tec's. I have invested over 10000$ in development. There are to many functions to list and it is growing as the software develops. I have no formal training in programming so a lot of learning has been done.
Functions:
SIMULATE
* Simulate 4-20mA (sink / source). Additionally monitor loop voltage, supply voltage and return voltage drop simultaneously
* Simulate frequency (AC / DC) 0- 24 volts additional configuration to allow for k-factor entry for simulating flow meters
* Simulate RTD
* Simulate Thermocouple
* Simulate voltage output and mV
MEASURE
* Measure 4-20mA (fuse less)
* Measure voltage
* Measure RTD
* Measure Thermocouple
* Measure frequency
* Measure resistance
* Basic oscilloscope 200Ksps
MISC
* Battery voltage indicator
* Backlight
* Internal temp display
* Auto power off
This is what makes it unique:
* Serial data input (pseudo HyperTerminal) RS485, RS232
* Serial data output (WITS oilfield specific) RS485, RS232
* Oilfield specific serial output functions
* several other oilfield related functions
everything is very protected, the protection circuitry took the majority of the work. it is impossible to wreck any I/O unless you apply more than 30 volts. Case is water proof, uses switcher power supplies so it will efficantly work on battery voltage from 6.5 to 25. LiPo, alkaline, NiMh ect all work. 24 hr battery life, auto power off ect............





I hope The teensy 2.0++ Is not discontinued or i'm gonna be out some dollars and effort!!
