RamjetX T3PA and Pro Load Cell

thingiverse

Here is the rewritten text: Updated 18/08/2020 This quick update shows my latest T3PA load cell mod, now integrated with the T3PA Pro mount. I've added the Inverted V2 T3PA Pro slide-on cover, a must-have for inverted pedal configurations. To align this correctly, simply move the mounting case to its last screw – you'll figure it out easily enough. Regarding code updates, I've incorporated the latest release of my code, greatly simplifying it while adding support for throttle and clutch pedals. A notable change is the absence of a MODE_BUTTON on Pin 2 for reset zero/binding/sensitivity. Instead: * Press for less than three seconds to enter binding mode – this will automatically press the pedal in game controls setup. * Press and hold for three to ten seconds to reset zero, useful if your pedal isn't reading correctly at zero. Note that it auto-zero's on power-up, so you'll rarely need this. * Hold for more than ten seconds to switch between low and high sensitivity – trust me, leave it on low (default). If you're curious about what the code is doing, simply open the serial monitor; it will send messages to the serial port when you press the button. Electrical-wise, I've done something different here by using IO pins as virtual grounds. This allows direct attachment of the HX711 to the pro-micro, with VCC, A3, A2, and A1 lining up perfectly. I've used A3 and A2 for data and A1 in digital mode as an output low to provide the GND pin for the HX711 – it's pretty cool and efficient. This case also supports the XFW-HX711 board, thanks to its dimensions and easy access to the 0-ohm resistor and 80Hz pads. If your pedal feels laggy, you might not have modded the HX711 board to 80Hz – see the attached picture for how to do this. Enjoy, and catch up with me on Discord at simhubs channel.
