аврстудия стоит у кого тутошних?

Hello All!

сам оригинал скомпилил (там две неправильности были у автора теперь с полушагом тыркаюсь

SS> -- SS> у автора так:

SS> // для полушага SS> //unsigned char stepper_step_codes[8] = { SS> // 0b00100000, SS> // 0b00110000, SS> // 0b00010000, SS> // 0b00011000, SS> // 0b00001000, SS> // 0b00001100, SS> // 0b00000100, SS> // 0b00100100 SS> //};

SS> // для полношага SS> //unsigned char stepper_step_codes[4] = { 0b00100000, 0b00010000, SS> 0b00001000, // 0b00000100 };

SS> uint8_t stepper_step_codes[4][4] = { SS> { 1, 0, 0, 0 }, SS> { 0, 1, 0, 0 }, SS> { 0, 0, 1, 0 }, SS> { 0, 0, 0, 1 } SS> }; SS> unsigned char stepper_current_step;

SS> --

вот так если uint8_t stepper_step_codes[8][8] = { { 1, 0, 0, 0 }, { 1, 1, 0, 0 }, { 0, 1, 0, 0 }, { 0, 1, 1, 0 }, { 0, 0, 1, 0 }, { 0, 0, 1, 1 }, { 0, 0, 0, 1 }, { 1, 0, 0, 1 } }; unsigned char stepper_current_step; то оно не в половину, а в 5 раз меньше поворачивается

Hello All!

SS> { 0, 1, 0, 0 }, SS> { 0, 1, 1, 0 }, все сделал, все гуд вышло
