hifi1: Приветствую всех. Кто-нибудь сталкивался, способен контроллер 3-й серии генерировать ИК команды управления техникой B&O? И считает ли их CNXLIR IR/Serial Learner с родного пульта Beo 4? Слышал что частота у команд этого производителя не стандартная Спасибо
Ответов - 3
eoulianov: Добрый! По ИК B&O рулится, всё ок. Старый learner его учил. На Beo4 есть нюанс с навигацией - на телевизоре выбирается с пипкой или без неё пульт, и если не правильно, то не работают курсорные кнопки. На разных реживах коды кнопок могут быть разными. В List можно выбрать функции, там все дискреты, управление кронштейном и выбор режима звуковой обработки. На ИК флешер нужно слать команды с несущей, а на джек IR IN - без неё, и если используется джек, то перестаёт слушаться пульта.
Pluvazeva: Учил старым лернером и новым, пульт beo4 без "пипки", громкость вверх работает вниз нет, кронштейн тоже в одну сторону, коды длинные , дело было давно, если есть коды на кронштейн и на громкость - поделитесь
olche: The B&O protocol has 5 periods that are all a multiple of 3125 uS. IR uses a fixed 200 uS on duration. Wired MCL (Master Control Link) uses an on duration of half the period. A code begins with two T1 one bits to set AGC and a start bit, it ends with a stop bit. Repeated codes repeat the entire code including the start and stop bits. Consecutive 0 or 1 bits are not allowed! The 'same as last' code must be used for repeated 0 or 1 data bits. For example the code 1010111000011 would be sent as: T1 T1 T5 T3 T1 T3 T1 T3 T2 T2 T1 T2 T2 T2 T3 T2 T4 AGC St 1 0 1 0 1 1 1 0 0 0 0 1 1 Sp T1 0 3125 uS T2 Same as last 6250 uS T3 1 9375 uS T4 Stop 12500 uS T5 Start 15625 uS The carrier frequency for IR is exactly 455 kHZ. The B&O IR receivers are sensitive and *very* selective. They use 455 kHz ceramic filters (same as an AM radio) to achive high selectivity. It is important to have a precise carrier frequency for maximum range. B&O remotes all use a crystal that is a multiple of 455 kHz (3.64 MHz for example) or a 455 kHz resonator. All unidirectional codes have 17 (mostly) or 20 (very few) data bits. Bidirectional codes are longer and have many different lengths. This document describes unidirectional codes only. Most B&O equipment from circa 1985 to present will respond to 455 kHz unidirectional codes. Each code has a single link bit, 8 or 11 device code bits, and 8 key code bits. 17 (11h) bits: l dddd dddd kkkk kkkk 20 (14h) bits: lddd dddd dddd kkkk kkkk When one of the device selection keys is pressed (Radio, TV, etc...) the device code is changed for the general purpose keys. For example selecting the RADIO will send 11:00181. Then VOL Up will send 11:00160. (length:code in hex) If the TV is then selected, code 11:00080 will be sent and VOL Up will now send 11:00060. The Volume keys will always use device code 000 or 001, the other general purpose keys will used the exact set device code. For example selcting V.TAPE will cause the volume keys to use device code 000, but the other keys will use device code 005.

A few other keys will send a code once when pressed (D), and then repeat with an other code while held down (H).
