When building using
default_envs = macOSin the platformio.ini file there are a number of build warnings like this:'sprintf' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Wdeprecated-declarations]
As discussed on the discord I've updated these using the
snprintf([variableName], sizeof([variableName]), ..)pattern.
