The simplest way is to add it to the address list and do

Code:

CEEdit1MR = AddressList.getMemoryRecordByDescription("Name of memory record")
if not CEEdit1MR then print("Failed to find memory record for CEEdit1MR")
else
CEEdit1UpdateTimer = createTimer()
CEEdit1UpdateTimer.Interval = 1000 -- update once a second
CEEdit1UpdateTimer.OnTimer = function(t)
CETrainer.CEEdit1.Text = CEEdit1MR.Value
end

-- called when the user presses enter
CETrainer.CEEdit1.OnEnter = function(sender)
CEEdit1MR.Value = CETrainer.CEEditBox1.Text -- or sender.Text
end
end

Those could be set in the gui editor in which case it'd look more like

Code:

function CETrainer_CEEdit1Enter(sender)
...
end

just because that's how the event handlers are named by default (form_name_event_without_on) and the gui sets the function based on the name in the trainer rather than assigning the function directly with lua.

there's also readBytes(address,numBytes) and writeBytes(address,numBytes) if you want to do it yourself for whatever reason.

Used the following code to read 1 byte signed value:

Code:

local val = readBytes(addr)
if val > 127 then
UDF1.CEEdit1.Text = val - 256
else
UDF1.CEEdit1.Text = val
end

By default, CEEdit1 can also write the value as signed. So, you do not need to write special code for that.
