| >From the data sheet: | ||
| Register 24'h20004 PCI Interrupt Status | ||
| bit [18] IR_SMP_INT Set when 32 input samples have been collected over | ||
| gpio[16] pin into GP_SAMPLE register. | ||
|
|
||
| What's missing from the data sheet: | ||
|
|
||
| Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5 | ||
| compat remote) | ||
| set register 0x35C050 to 0xa80a80 | ||
|
|
||
| enable sampling | ||
| set register 0x35C054 to 0x5 | ||
|
|
||
| Of course, enable the IRQ bit 18 in the interrupt mask register .(and | ||
| provide for a handler) | ||
|
|
||
| GP_SAMPLE register is at 0x35C058 | ||
|
|
||
| Bits are then right shifted into the GP_SAMPLE register at the specified | ||
| rate; you get an interrupt when a full DWORD is recieved. | ||
| You need to recover the actual RC5 bits out of the (oversampled) IR sensor | ||
| bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data) An | ||
| actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment. | ||
|
|
||
| I'm pretty sure when no IR signal is present the receiver is always in a | ||
| marking state(1); but stray light, etc can cause intermittent noise values | ||
| as well. Remember, this is a free running sample of the IR receiver state | ||
| over time, so don't assume any sample starts at any particular place. | ||

| This data sheet (google search) seems to have a lovely description of the | ||
| RC5 basics | ||
|
|

| http://users.pandora.be/nenya/electronics/rc5/ and more data | ||
|
