/*
|
||||
* This driver has currently only been tested on the IRWave IR320ST-2
|
||||
*
|
||||
* PROTOCOL:
|
||||
*
|
||||
* The protocol for talking to the TOIM3232 is quite easy, and is
|
||||
* designed to interface with RS232 with only level convertors. The
|
||||
* BR/~D line on the chip is brought high to signal 'command mode',
|
||||
* where a command byte is sent to select the baudrate of the RS232
|
||||
* interface and the pulse length of the IRDA output. When BR/~D
|
||||
* is brought low, the dongle then changes to the selected baudrate,
|
||||
* and the RS232 interface is used for data until BR/~D is brought
|
||||
* high again. The initial speed for the TOIMx323 after RESET is
|
||||
* 9600 baud. The baudrate for command-mode is the last selected
|
||||
* baud-rate, or 9600 after a RESET.
|
||||
*
|
||||
* The dongle I have (below) adds some extra hardware on the front end,
|
||||
* but this is mostly directed towards pariasitic power from the RS232
|
||||
* line rather than changing very much about how to communicate with
|
||||
* the TOIM3232.
|
||||
*
|
||||
* The protocol to talk to the TOIM4232 chipset seems to be almost
|
||||
* identical to the TOIM3232 (and the 4232 datasheet is more detailed)
|
||||
* so this code will probably work on that as well, although I haven't
|
||||
* tested it on that hardware.
|
||||
*
|
||||
* Target dongle variations that might be common:
|
||||
*
|
||||
* DTR and RTS function:
|
||||
* The data sheet for the 4232 has a sample implementation that hooks the
|
||||
* DTR and RTS lines to the RESET and BaudRate/~Data lines of the
|
||||
* chip (through line-converters). Given both DTR and RTS would have to
|
||||
* be held low in normal operation, and the TOIMx232 requires +5V to
|
||||
* signal ground, most dongle designers would almost certainly choose
|
||||
* an implementation that kept at least one of DTR or RTS high in
|
||||
* normal operation to provide power to the dongle, but will likely
|
||||
* vary between designs.
|
||||
*
|
||||
* User specified command bits:
|
||||
* There are two user-controllable output lines from the TOIMx232 that
|
||||
* can be set low or high by setting the appropriate bits in the
|
||||
* high-nibble of the command byte (when setting speed and pulse length).
|
||||
* These might be used to switch on and off added hardware or extra
|
||||
* dongle features.
|
||||
*
|
||||
*
|
||||
* Target hardware: IRWave IR320ST-2
|
||||
*
|
||||
* The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
|
||||
* TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever.
|
||||
* It uses a hex inverter and some discrete components to buffer and
|
||||
* line convert the RS232 down to 5V.
|
||||
*
|
||||
* The dongle is powered through a voltage regulator, fed by a large
|
||||
* capacitor. To switch the dongle on, DTR is brought high to charge
|
||||
* the capacitor and drive the voltage regulator. DTR isn't associated
|
||||
* with any control lines on the TOIM3232. Parisitic power is also taken
|
||||
* from the RTS, TD and RD lines when brought high, but through resistors.
|
||||
* When DTR is low, the circuit might lose power even with RTS high.
|
||||
*
|
||||
* RTS is inverted and attached to the BR/~D input pin. When RTS
|
||||
* is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
|
||||
* RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
|
||||
* mode'.
|
||||
*
|
||||
* For some unknown reason, the RESET line isn't actually connected
|
||||
* to anything. This means to reset the dongle to get it to a known
|
||||
* state (9600 baud) you must drop DTR and RTS low, wait for the power
|
||||
* capacitor to discharge, and then bring DTR (and RTS for data mode)
|
||||
* high again, and wait for the capacitor to charge, the power supply
|
||||
* to stabilise, and the oscillator clock to stabilise.
|
||||
*
|
||||
* Fortunately, if the current baudrate is known, the chipset can
|
||||
* easily change speed by entering command mode without having to
|
||||
* reset the dongle first.
|
||||
*
|
||||
* Major Components:
|
||||
*
|
||||
* - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
|
||||
* to IRDA pulse timings
|
||||
* - 3.6864MHz crystal to drive TOIM3232 clock oscillator
|
||||
* - DM74lS04M Inverting Hex line buffer for RS232 input buffering
|
||||
* and level conversion
|
||||
* - PJ2951AC 150mA voltage regulator
|

* 9. Should then be in data mode
|

*
|

* Because the IR320ST-2 doesn't have the RESET line connected for some reason,
