-# PWM fan control
+Контроллер питания и охлаждения. 
+===============================
+
+-- Четыре канала измерения температуры с точностью +-1degrC (три канала управляют активностью кулеров, четвертый - для общего отключения питания в случае достижения критической температуры).
+-- Два канала управления четырехпроводными кулерами с контролем их активности.
+-- Две кнопки управления (включить/экстренно выключить нагрузку).
+-- Внешний сигнал (пищалка 12В): короткий сигнал раз в 10 секунд - один из кулеров не вращается (а должен), непрерывные сигналы - критическая ситуация, питание скоро будет отключено, (сигналы в течение 4с с паузой в 6с - резерв).
+-- Режим ручного управления (без контроля температур с соответствующими действиями) или мониторинга (в этом режиме нельзя вручную задавать параметры кулера или внешнего сигнала).

+'0x' - turn cooler0 on/off (x=1/0) or get status (x - any other)

+```
+
+=== 0x,1x ===
+x=='0' - выключить питание кулера; x=='1' - включить питание; любое другое значение - проверить состояние.
+
+=== Ax ===
+x=={0..7} - получить "сырое значение" x-го канала АЦП (в ADU). 
+Каналы: 0..3 - термометры, 4 - измерение 12В, 5 - измерение 5В, 6 - температура МК, 7 - уровень 3.3В.
+
+=== B ===
+Состояние обеих кнопок, например:
+```
+BUTTON0=0
+BUTTON1=0
+```
+
+Нажатие кнопок проверяется один раз в секунду. Кнопка BUTTON0 переводит систему в автоматический режим и включает реле. Кнопка BUTTON1 отключает реле, отключает все кулеры и сигнал и переводит систему в ручной режим.
+
+=== bx ===
+Изменить состояние внешнего сигнала. 0 - выключить, 1 - включить серию непрерывных сигналов, l - включить серию коротких сигналов в течение 4 секунд с паузой в 6 секунд, s - включить короткий сигнал (0.5с) с паузой 9.5с.
+
+=== Cx ===
+Получить значения скорости вращения четырехпроводного кулера (обороты в секунду). Например:
+```
+C0
+RPM0=78
+C1
+RPM1=0
+```
+
+=== D ===
+Активировать режим DFU для перепрошивки. После прошивки нужно перезапустить МК, закоротив контакты "reset" или кратковременно отключив от питания.
+
+=== E ===
+Отобразить текущее состояние системы, например:
+```
+TIME=1229247
+T0=293
+T1=264
+T2=262
+T3=254
+BUZZER=OFF
+BUTTON0=0
+BUTTON1=0
+RPS0=82
+RPS1=107
+PWM0=30
+PWM1=40
+PWM2=33
+COOLER0=1
+COOLER1=1
+RELAY=1
+```
+Где 
+TIME - время с момента включения (мс, приблизительно);
+Tx - температуры (x10) соответствующих каналов в градусах Цельсия;
+BUZZER - состояние сигнала;
+BUTTONx - состояние кнопок (1 - нажата, 0 - отпущена);
+RPSx - скорость вращения кулера x (оборотов в секунду);
+PWMx - установленное значение ШИМ (в процентах, 0..100) канала x;
+COOLERx - включено ли питание кулера x (0..1), из-за неправильной схемотехники не рекомендуется отключать питание четырехпроводных кулеров (+12В поступает в этом случае на измерительный вход);
+RELAY - состояние реле (1 - включено, 0 - выключено).
+
+=== Gx ===
+Отобразить значения настройки ШИМ кулера x.
+
+=== M ===
+Отобразить температуру МК (приближенная температура, x10 градусов Цельсия).
+
+=== m ===
+Переключить (вкл/выкл) режим мониторинга, когда каждые 5 секунд отображается состояние системы.
+
+=== R ===
+Программный перезапуск системы.
+
+=== rx ===
+x==0 - выключить реле, x==1 - включить реле, любое другое значение - получить состояние реле.
+
+=== Sx y ===
+Установить значение заполнения ШИМ кулера x (0..2) в y (0..100). Согласно опыту, четырехпроводные кулеры не стартуют при значении PWM<15, а двухпроводные не стартуют при PWM<35, поэтому для получения малых оборотов необходимо стартовать на большей скорости, а затем уже установить нужное значение заполнения ШИМ.
+
+=== s ===
+Отобразить "вшитые" в код настройки, например:
+```
+Thysteresis=30
+Tmin={400, 350, 350}
+Tmax={900, 800, 600}
+T3max=850
+```
+
+В данном случае гистерезис температуры установлен в 3 градуса, область допустимых значений температур - 40..90 градусов для канала 0, 35..80 градусов для канала 1 и 35..60 градусов для канала 2. Критическая температура канала 3 установлена в 85 градусов. Если в течение 20 секунд превышено значение одной из критических температур (для T0..2 они равны Tmax+Thysteresis), то реле отключается, система остается в автоматическом режиме.
+
+=== T ===
+Отобразить время (условное) в миллисекундах со старта.
+
+=== tx ===
+Получить значение температуры x-го канала (0..3). Температура умножена на 10. Например:
+```
+t0
+T0=294
+t1
+T1=265
+t2
+T2=264
+t3
+T3=256
+```
+
+Соответственно, температуры равны: t0=29.4, t1=26.5, t2=26.4 и t3=25.6.
+Учитывая то, что величина вычисляется кусочно-линейной аппроксимацией с погрешностью до 0.1 градуса, а сами NTC дают разброс не лучше +-0.5 градуса, не стоит надеяться на то, что температуры будут достаточно точными.
+
+=== V ===
+Получить значения напряжения (x100) в каналах, например:
+```
+V3_3=330
+V5=428
+V12=1055
+```
+Означает, что питание МК =3.3В, на входе 5В присутствует 4.28В, а на входе 12В присутствует 10.55В.
+
+=== Z ===
+Реинициализация АЦП (ХЗ, зачем я это добавил).
+
+=== ! ===
+Переключение между автоматическим и ручным режимами управления.
+
+
+
+
+
