|
||||

// Main Detection Loop
|
||||
// The Univac-Sperry F3W9 has a convenient feature, an internal 8 key buffer
|
||||
// This buffer is only emptied (i.e. sent over the bus) when the REQUEST line is held high
|
||||
// Because of this, we can utilize the scan_loop to do all of the critical processing,
|
||||
// without having to resort to interrupts, giving the data reading 100% of the CPU.
|
||||
// This is because the USB interrupts can wait until the scan_loop is finished to continue.
|
||||
//
|
||||
// Normally, this approach isn't taken, as it's easier/faster/safer to use Teensy hardware shift registers
|
||||
// for serial data transfers.
|
||||
// However, since the Univac-Sperry F3W9 sends 20 bit packets (including the start bit), the Teensy
|
||||
// doesn't have a shift register large enough (9 bit max), to hold the data.
|
||||
// So the line must be polled manually using CPU cycles
|
||||
//
|
||||
// Another interesting feature is that there are 2 data lines.
|
||||
// Output and /Output (NOT'ted version).

// Not really useful here, but could be used for error checking, or eliminating an external NOT gate if

|
||||
// - Thus the average packet length is 2.205 msecs
|
||||
// - Each packet is separated by at least 240 usecs (during a buffer unload)
|
||||
// - While holding the key down, each packet has a space of about 910 usecs
|
||||
// - A max of 8 keys can be sent at once (note, the arrow keys seem use 2 packets each, and thus take up twice as much buffer)
|
||||
// - There is no timing danger for holding the request line, just that data may come in when you don't want it
|
||||
|
||||
// Now that the scan loop has been entered, we don't have to worry about interrupts stealing
|
||||
// precious cycles.

|

|

|
||||
// - 1 bit : 105 usecs is 16 000 000 * 0.000105 = 1680 instructions
|
||||
// - Bit centering : 52.5 usecs is 16 000 000 * 0.0000525 = 840 instructions
|
||||
// - Delay : 5 msecs is 16 000 000 * 0.005 = 80 000 instructions
|
||||
// - Microsecond : 1 usec is 16 000 000 * 0.000001 = 16 instructions
|
||||
//
|
||||
// Now, either I can follow these exactly, or based upon the fact that I have >840 tries to find the
|
||||
// the start bit, and >1680 tries to read the subsequent bits, I have some "flex" time.
|
||||
// Knowing this, I can make some assumptions that because I'm only reading a total of 20 bits, and will
|
||||
// be re-centering for each packet.
|
||||
// This will allow for less worrying about compiler optimizations (and porting!).
|
||||
|
||||
// The basic idea is to find a "reliable" value for the start bit, e.g. read it ~10 times.
|
||||
// Using a for-loop and some addition counters, this should eat up approximately 20-30 instructions per read
|
||||
// (very loose estimation).
|
||||
// So reading 10 * 30 instructions = 300 instructions, which is much less than 840 instructions to where the
|
||||
// bit center is, but is close enough that further delays of ~>1680 instructions will put the next read
|
||||
// within the next bit period.
