Harald Welte ba0c688103 owhw: Make owhw/board.h the default for now

Harald Welte 4dc3db7beb req_ctx: Use only 10 small buffers, and no large ones 2016-02-28 19:32:01 +01:00
Harald Welte 203ea19227 req_ctx: Use the linked lists between req_ctx to ensure ordering 
It is important we send the buffers in-order, and not re-order
them between the main program and the USB host.

Harald Welte 17db2f1112 card_emu: Fix PTS checksum verification 
If the checksum doesn't match, the card should not apply any Fi/Di
changes, not respond anything and simply expect the next TPDU.

Harald Welte 22cdf2af59 card_sim: fix passing handle to tc_etu_*() functions 2016-02-24 22:18:11 +01:00
Harald Welte 6bf8c12b13 update card_emu_tests to recent card_emu changes 2016-02-24 21:04:08 +01:00
Harald Welte 042f0d366b tc_etu: Add explicit enable/disable functions 
We don't want the tc_etu to call into card_emu at all times,
e.g. while clock is applied, but RST is not yet present.

Rather, we want to explicitly enable it once RST is released
 2016-02-24 21:01:50 +01:00
Harald Welte 855ba9e168 card_emu: Ensure TX happens synchronously before state changes 
we cannot first chage the state and then transmit the byte
asynchronously later, this introduces race conditions.  Do it
in-line by explicit calls to the UART Tx function.
 2016-02-24 21:00:46 +01:00
Harald Welte 849269f4cc add OWHW board.h file 2015-11-30 12:16:53 +01:00

Harald Welte 4d8046743e card_emu: Fix state transitions for both Rx and Tx data phase 
We now use the P3 value to determine how many characters to
receive (in case of Reader->Card payload phase).

how we proceed changes depending on whether we should continue to
receive or transmit...
 2015-11-14 20:59:56 +01:00
Harald Welte 05b41c62f6 card_emu: fix set_tpdu_state() 
* don't enter a state we are already in
* enable the UART receiver not only when waiting for CLA, but also
  generally when we're waiting for more data from the reader
 2015-11-14 20:58:48 +01:00
Harald Welte 2935b3c479 card_emu: detect end of TX data from CEMU_DATA_F_FINAL 
When the USB host software sets this flag, we terminate the
TPDU transmission after the last character in this frame and
transition again to the WAIT_TPDU state.
 2015-11-14 20:00:14 +01:00

Harald Welte 9d3e38242c initial commit of more code towards card emulation 
I couldn't help but to spend my sunday on working towards card
emulation, including
* various state machines in the target about ISO7816 states
* tc_etu timer import from simtrace1
* req_ctx import from simtrace1 (needs renaming and simplifiation)
* USB protocol description as cardemu_prot.h
* some host-based testing code to test the state machines

The code seems to work fine throughout card reset, sending ATR and
receiving the TPDU header of the first APDU, up to the point where it
marks the TPDU header as to-be-transmitted over th bulk-in endpoint.

Sending the ATR must be done inside the firmware for timing
requirements.

From that point onwards, the host needs to respond at the very least
with a procedure byte, and some indication whether or not the card
emulator should continue to transmit data (card->reader), or receive
data (reader->card).

The code is intentionally not hooked up yet with the USB logic nor with
the UART.  I want host-based testing completed before doing that.

Harald Welte 6d44c1fdd3 USB: Add manufacturer name string descriptor 
... and use indexed array initializers for more safety/clarity
 2015-11-07 19:01:30 +01:00
Harald Welte 8a5b580a72 CCID usb descriptor: We support 3V only, not 5V. 2015-11-07 18:53:43 +01:00
Harald Welte ec4fe2358b Mark more local functions as static 2015-11-07 18:48:26 +01:00
Harald Welte 844db577f2 change to own USB vendor/device ID 
we shouldn't re-use the vendor/device ID usd by simtrace1, as the
protocol is incompatible and applications for simtrace 1 don't work with
simtrace2.   Also, there's a different processor architecutre in the
hardware.
 2015-11-07 18:38:04 +01:00
Harald Welte beb729391b USB descriptors: call it SIMtrace 2 and add spaces to strings 2015-11-07 18:35:41 +01:00
Harald Welte 8d6a5d8f89 move USBDDriverCallbacks_ConfigurationChanged() to main.c 
This alows us to mark simtrace_config as static variable and keep all
code related to this variable local to main.c
 2015-11-07 18:27:05 +01:00
Harald Welte d4c1421c91 conf_func: Mark const and static. 
const saves RAM, and static avoids namespace pollution.
 2015-11-07 18:25:46 +01:00
Harald Welte fefd571701 conf_func: Use named struct initializers and named array subscripts 
As part of this, we also do away with the '-1' based array subscripts
 2015-11-07 18:25:19 +01:00
Harald Welte 15d72cc631 add some comments on the conf_func members 2015-11-07 18:19:06 +01:00
