Label fmt_string

[SDOHFE]

I seem to be having some difficulties with the string formatters. Is there a better description of the formatters that are supported?

The String Format worked in the same way as the using of printf in C or C++

OK, thats how I thought it was based off of and I believe I have that correct.

Under the [VARIABLE] section, is there a better explanation of vartype and datatype?

For testing, I am just trying to display battery voltage.

This is what I have pertaining to that message, variable, and label:

Hello,

label3 is used to dispaly the voltage, and uses variable "VOLTS".
fmt_string="%3.2f Volts" indicates that the variable has to be float type.
Variable "VOLTS" has got vartype=2 which is float (correct)
datatype is also set to 2 (float) which means that the value on the CAN-Bus is a float value. A float-value on the CAN-bus is very unusual, usually unsigned or signed integer is used.
position=40,16 shows that on the CAN-Bus this is a 16bit value, and I would assume it is an integer value.
Please set datatype to 0 (unsigned) or 1 (signed), this depends on how the vaylue is transmitted.
