Hello All,

 

I want to print the character '%' in sprintf. How can I achieve this?

friendly regards

Ellen

 

sprintf(s,"PV %dWh P %dWh b %dA %d%", (int)SumPv, (int)SumLinePowerBat, (int)Charge_DischargePowerTotal, PercentBatCap);

the output should be at the last item: 45%. The compiler ignores the last char and gives me this warning:

Severity

Description

File

Line

Warning

 

spurious trailing '%' in format [-Wformat=]

C:\Users\User2\Documents\Atmel Studio\7.0\Solarmon\SolarmonV02\Utils.c

% A % followed by another % character will write a single % to the stream. %
