puts, printf

[Lukac Michal]

Zdravim,
pozeram si SDK k Pi Pico C/C++ a v niektorych prikladoch je pouzite puts a printf ako v priklade nizsie.
Preco sa pouziva aj puts aj printf? Nemoze byt v tom prvom pripade tiez printf?

dik,
m.


int main() {

  stdio_init_all();

  #if !defined(i2c_default) || !defined(PICO_DEFAULT_I2C_SDA_PIN) || !defined(PICO_DEFAULT_I2C_SCL_PIN)
  #warning i2c/mpu6050_i2c example requires a board with I2C pins
  puts("Default I2C pins were not defined");

  #else
  printf("Hello, MPU6050! Reading raw data from registers...\n");

  // This example will use I2C0 on the default SDA and SCL pins (4, 5 on a Pico)
  i2c_init(i2c_default, 400 * 1000);
  ...
