I started in programming, I did some switch and now I try to operate a stepper motor to engine RPM but I have some worries code for FS2020
message error :
ERROR - error in dataref callback: logic.lua:11: attempt to index a number value (local 'rpm')
Can you help me?
Thanks
Code: Select all
stepper_rpm = hw_stepper_motor_add("Engine RPM", "4WIRE_4STEP", 945, 30)
-- Initialization starting, rotate clockwise for 3 seconds
hw_stepper_motor_position(stepper_rpm, nil, "ENDLESS_CLOCKWISE")
timer_start(3000, function(count)
hw_stepper_motor_calibrate(stepper_rpm, 0.0)
hw_stepper_motor_position(stepper_rpm, 0.0)
local function PT_rpm_FSX(rpm)
engine_rpm = var_cap(rpm[1], 0, 3500)
-- The stepper motor position is set as a value from 0 to 1, so we have to convert the RPM to a position.
-- Therefore we divide 1 by 3500, this is then multiplied with the current RPM.
hw_stepper_motor_position(stepper_rpm, 1 / 3500 * engine_rpm)
end
fs2020_variable_subscribe("PROP RPM:1", "RPM", PT_rpm_FSX)
end)
