From 7435ac81de2ebe5b312b2435795c4c027d6add75 Mon Sep 17 00:00:00 2001 From: Paul Selkirk Date: Wed, 8 Apr 2015 16:38:45 -0400 Subject: Add EIM HAL. The eim and i2c support are copied from core/platform/novena. In future, we should maybe build a library there, and link it here. --- src/tc_eim.h | 50 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 src/tc_eim.h (limited to 'src/tc_eim.h') diff --git a/src/tc_eim.h b/src/tc_eim.h new file mode 100644 index 0000000..5da18e4 --- /dev/null +++ b/src/tc_eim.h @@ -0,0 +1,50 @@ +/* + * tc_eim.h + * -------- + * This module contains common code to talk to the FPGA over the EIM bus. + * + * Author: Paul Selkirk + * Copyright (c) 2014-2015, NORDUnet A/S All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: + * - Redistributions of source code must retain the above copyright notice, + * this list of conditions and the following disclaimer. + * + * - Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * + * - Neither the name of the NORDUnet nor the names of its contributors may + * be used to endorse or promote products derived from this software + * without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS + * IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED + * TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A + * PARTICULAR PURPOSE ARE DISCLAIMED.
