Question

Main.cpp:31:2: error: stray '\302' in program
cout

Answer 1

Answer:

For some weird reason, the following code doesn't compile. I get a "stray '\302' in program" error around volatile unsigned int encoderPos = 0;, and I have no idea what the issue is. I've been trying to figure this out for over 40min, and nothing works. It doesn't make any sense

#include <U8g2lib.h> #include <SPI.h> //Pin definitions: const int control_PWM = A3; //PWM output for the delay const int btn_1 = 1; //Button for mode 1 const int btn_2 = 4; //Button for mode 2 const int btn_3 = 5; //Button for mode 3 const int r_A = 2; //Rotary encoder A's data const int r_B = 3; //Rotary encoder A's data const int r_SW = 0; //Rotary encoder's button data const int oled_CLK = 9; //SPI cloack const int oled_MOSI = 8; //MOSI pin const int oled_CS = 7; //Chip Select pin const int oled_DC = 6; //OLED's D/C pin U8G2_SH1106_128X64_NONAME_F_4W_HW_SPI u8g2(U8G2_R0, /* cs=*/ 10, /* dc=*/ 9, /* reset=*/ 8); int mode = 1; //1: RGB, 2: HSL, 3: Distance control int value_selection = 1; //Actual value selectrion int value1 = 0; //red in mode 1; tint in mode 2 int value2 = 0; ////green in mode 1; saturation in mode 2 int value3 = 0; //blue in mode 1; luminosity in mode 2 volatile unsigned int encoderPos = 0; // rotary encoder's current position unsigned int lastReportedPos = 1; // rotary encoder's previous position static boolean rotating=false; // is the encoder activity status // interrupter variables boolean A_set = false; boolean B_set = false; boolean A_change = false; boolean B_change= false; void setup() { } void loop() { }
