From now on, we only need<br>to parse the string once since we store the device type after first<br>during open time.<br><br>Later on, more fields will be moved to device-type specific structure,<br>such as Tx timing offset, clock rate, etc.<br><br>Change-Id: I7658615787c5bc41c365bab9c11733b701ac2ae5<br>---<br>M Transceiver52M/device/lms/LMSDevice.cpp<br>M Transceiver52M/device/lms/LMSDevice.h<br>2 files changed, 89 insertions(+), 22 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/osmo-trx refs/changes/76/16876/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/Transceiver52M/device/lms/LMSDevice.cpp b/Transceiver52M/device/lms/LMSDevice.cpp</span><br><span>index a533e7e..2e164ed 100644</span><br><span>--- a/Transceiver52M/device/lms/LMSDevice.cpp</span><br><span>+++ b/Transceiver52M/device/lms/LMSDevice.cpp</span><br><span>@@ -20,6 +20,9 @@</span><br><span> #include <stdint.h></span><br><span> #include <string.h></span><br><span> #include <stdlib.h></span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span style="color: hsl(120, 100%, 40%);">+#include <map></span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span> #include "Logger.h"</span><br><span> #include "Threads.h"</span><br><span> #include "LMSDevice.h"</span><br><span>@@ -44,11 +47,62 @@</span><br><span> #define LMS_CALIBRATE_BW_HZ OSMO_MAX(GSM_CARRIER_BW, LMS_MIN_BW_SUPPORTED)</span><br><span> #define SAMPLE_BUF_SZ (1 << 20) /* Size of Rx timestamp based Ring buffer, in bytes */</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span style="color: hsl(120, 100%, 40%);">+/* Device Name Prefixes as presented by LimeSuite API LMS_GetDeviceInfo(): */</span><br><span style="color: hsl(120, 100%, 40%);">+#define LMS_DEV_SDR_USB_PREFIX_NAME "LimeSDR-USB"</span><br><span style="color: hsl(120, 100%, 40%);">+#define LMS_DEV_SDR_MINI_PREFIX_NAME "LimeSDR-Mini"</span><br><span style="color: hsl(120, 100%, 40%);">+#define LMS_DEV_NET_MICRO_PREFIX_NAME "LimeNET-Micro"</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span style="color: hsl(120, 100%, 40%);">+/* Device parameter descriptor */</span><br><span style="color: hsl(120, 100%, 40%);">+struct dev_desc {</span><br><span style="color: hsl(120, 100%, 40%);">+ /* Does LimeSuite allow switching the clock source for this device?</span><br><span style="color: hsl(120, 100%, 40%);">+ * LimeSDR-Mini does not have switches but needs soldering to select</span><br><span style="color: hsl(120, 100%, 40%);">+ * external/internal clock.
