[1.5 RC3] TELEMETRY_ACTIVE Source do not get updated?

[JimB40]

Doing some mor LUA tests.

X18S with ELRS module

1. Telemetery stream not present (EXT 0%)
2. Telemetry stream present (EXT 100%)

Can I check in LUA if RC link is active (telemetry stream available)? Source value reading from LUA for CATEGORY_SYSTEM_EVENT,TELEMETRY_ACTIVE is not updated to my test?

Although in ETHOS UI same event (System event, Telemetry active) gets highligted when telemetry stream shows.

BTW shouldn it be boolen (false/true)? Strange readings anyway. member (suppose to be int8) is 3.0 decimal is 0 but value is 0.0 with one decimal.

X16S? Should I understand X18S?

I have a doubt, is your screen refreshed?

(Perhaps you are used to OpenTX / EdgeTX where the screen is ALWAYS refreshed, which is already a problem on X12S, but which becomes even worst with the bigger resolution LCDs!)

Perhaps you could share your script (or parts of it) so that I can try to help if I find spare time?

As a first test, and because your script doesn't look too much complex, I would call lcd.invalidate() in the wakeup() method, to mimic OpenTX behaviour.

member (suppose to be int8) is 3.0

Fixed (ready for 1.5.0 RC5), it should be an integer. Doc updated.

decimal is 0 but value is 0.0 with one decimal.

Value is a number. 0.0 = 0 = False

Invalidated. Printed also on console via serial port and value=0.0 all the time

local appicon = lcd.loadMask("appicon.png")

local m, t, tlm

local gS = function (c,m, o)
  return system.getSource( { category=c, member=m, options=o } )
end

local event = function (w, et, e, x, y)
  if e then
    lcd.invalidate()
  end
end

local run = function()
  lcd.invalidate()
  m = system.getMemoryUsage()
  t = os.clock()*100
end

local draw = function()
  lcd.color(WHITE)
  lcd.font(FONT_S)
  if m then
    lcd.drawText(0,0,'Total: '..m.ramAvailable)
    lcd.drawText(0,20,'Stack: '..m.mainStackAvailable)
    lcd.drawText(0,40,'LUA: '..m.luaRamAvailable)
    lcd.drawText(0,60,'Bitmaps: '..m.luaBitmapsRamAvailable)
  end
  if t then
    lcd.drawText(0,80,'Clock: '..t)
  end
  if appicon then
    lcd.drawText(0,120,'icon w: '..appicon:width())
    lcd.drawText(0,140,'icon h: '..appicon:height())
  end
  if tlm then
    lcd.drawText(240,0,"tlm variable (Source)")
    lcd.drawText(240,20,"Source::category "..tostring(tlm:category()))
    lcd.drawText(240,40,"Source::member "..tostring(tlm:member()))
    lcd.drawText(240,60,"Source::decimals "..tostring(tlm:decimals()))
    lcd.drawText(240,80,"Source::minimum "..tostring(tlm:minimum()))
    lcd.drawText(240,100,"Source::maximum "..tostring(tlm:maximum()))
    lcd.drawText(240,120,"Source::name "..tostring(tlm:name()))
    lcd.drawText(240,140,"Source::options "..tostring(tlm:options()))
    lcd.drawText(240,160,"Source::rawValue "..tostring(tlm:rawValue()))
    lcd.drawText(240,180,"Source::stringUnit "..tostring(tlm:stringUnit()))
    lcd.drawText(240,200,"Source::stringValue "..tostring(tlm:stringValue()))
    lcd.drawText(240,220,"Source::unit "..tostring(tlm:unit()))
    lcd.drawText(240,240,"Source::value "..tostring(tlm:value()))
  end
end

local init = function()
  tlm = gS(CATEGORY_SYSTEM_EVENT,TELEMETRY_ACTIVE)

  local p = {
    name = "Test",
    icon = appicon,
    event = event,
    paint = draw,
    wakeup = run,
  }
  system.registerSystemTool(p)
end

return {init=init}

Bug. It should return +100 or -100

Fix ready for 1.5.0 RC5
