Optional parameters for puts() #1
Description
Description
Right now, our puts() wrapper simply sends a null-terminated string over UART. To improve flexibility (for log levels, timestamps, or custom prompts), we’d like to allow callers to pass an optional parameter similar to std printf.
Important
To avoid breaking the current call of puts(“hello”), the parameter should be optional. Additionally, the API documentation should include example use cases.
Current behavior
// Send a null-terminated string over UART
void puts(const char *s);Desired behavior
void puts(const char *s, const char *param); // this is for example purpose, not sure about the datatype, yet
// Examples:
puts("System initialized\r\n");
// → “System initialized”
//
puts("Current time:\r\n", __TIME__); // or something similar than printf()
// → “Current time: 20:24:32”
