Always close your stuff before filling it. E.g. instead of typing ... switch (uint8_t bla){ case 0: stuff; ... ... and filling everything as you go along, first type the skeleton ... switch () {case: break; default: break;} ... and then fill everything in. It's anal/pedantic but it becomes second nature really fast. Do it for everything (loops, structs, functions,...). I once lost 2 entire days of my life I kid you not hunting an if (a = b) that had to be a == b and decided to change my approach.
