Amit érdemes tudni a Raspberry Pi-kről:
A legelső változat 2012-ben jelent meg. Pici, olcsó és nagyon alacsony fogyasztású, hobby-célú kártyagép. Felépítése ARM alapú, nem PC-architektúra, hanem kb. egy régi mobilhoz hasonló. Nagyon sok mindenre használható! A Linux-nak és a magas eladási mennyiségnek köszönhetően jelentős fejlesztőtáborral rendelkezik.

Sziasztok, rpi csomagtelepítésnél ez a hibaüzi fogadott, nem tudom hogy tudom javítani. Mi lehet a baj? megoldás?
üzi:
dpkg: unrecoverable fatal error, aborting:
files list file for package 'libsemanage-common' is missing final newline
E: Sub-process /usr/bin/dpkg returned an error code (2) -

Sziasztok, érdeklődnék mi a megoldás arra, hogy ne fagyon le a rendszer? néha semmit se lehet csinálni, putty is hibákat ír ki, nem reagál semmire sem.
Lehet egy olyan megoldás, ha újraindítom kihúzással akkor visszaáll egy alap állapotra?? Nem vagyok egy Linux guru, csak ötletelek a megoldáson.
Vagy egy USB pendriveról visszaállítás??
A segítséget előre is köszönöm.

A küldött (sendTelegram(code) értékére lennék kiváncsi, hogy tudom ezt kiszámolni?? :S
receivedCode=530713;
period=125;//Copy the received code.
code = receivedCode & 0xFFFFF; //truncate to 20 bits for show; receivedCode is never more than 20 bits..//Add the period duration to the code. Range: [0..511] (9 bit)
code |= (unsigned long)period << 23;//Add the number of repeats to the code. Range: [0..7] (3 bit). The actual number of repeats will be 2^(repeats),
//in this case 8
code |= 3L << 20;//Retransmit the signal on pin 11. Note: no object was created!
RemoteTransmitter::sendTelegram(code,10);Ha ez sikerülne talán RCSwitchel tudnám küldeni a helyes kódot.
