Yes, it works now.
 2011-01-22 12:24:12 -02:00
Bert Vermeulen 6ea7e23526 Revert "re-enable filter and datastore for DF_LOGIC" 
This reverts commit 23da86dfc0a89c7ab951fea31a318a493830eb69.
 2011-01-22 14:18:31 +01:00

Uwe Hermann 5819184b22 Remove duplicate FIRMWARE_DIR includes. 
We use AC_DEFINE_UNQUOTED in configure.ac now to put the FIRMWARE_DIR #define
in the config.h file, which is included where we need the #define.
 2011-01-21 21:14:37 +01:00
Daniel Ribeiro 62eeeb171b re-enable filter and datastore for DF_LOGIC 
This definitely isn't the proper fix, but it should allow DF_LOGIC
and DF_ANALOG to coexist.
 2011-01-21 18:04:09 -02:00
Daniel Ribeiro 81bbdf6a6a add incomplete DF_ANALOG support to output_gnuplot.c 
RAW->Voltage conversion is not implemented yet, its hardcoded for
signed 16bit conversion.
 2011-01-21 16:11:44 -02:00
Daniel Ribeiro 8038e90aef add a sine wave to demo.c 2011-01-21 12:52:12 -02:00
Daniel Ribeiro c3579621d5 reduce analog_sample sizes. 
To save resources, reduce the max ADC resolution and max probes
per device. Just increase when needed.

Soft limit: 256 probes, 16bit adc
Hard limit: 2^64 probes, 64 bit adc
 2011-01-21 11:25:50 -02:00
Daniel Ribeiro 764f887f7b change demo.c to output analog packets 
You need to #define DEMO_ANALOG to generate DF_ANALOG packets.
 2011-01-21 02:12:48 -02:00
Daniel Ribeiro 6eb0e3ea95 change output_text.c to support analog 
Only the "bits" output format was converted.
Analog values, are scaled down to A-Z letters.
 2011-01-21 02:12:48 -02:00
Daniel Ribeiro 48d783e4b5 introduce analog_sample datafeed packet 
These structs define the packet format used to exchange data using
the DF_ANALOG packet type.
 2011-01-21 02:12:48 -02:00
Daniel Ribeiro f3163a6c2e make output_analog.c = output_text.c 2011-01-21 02:12:48 -02:00
Uwe Hermann f95fd1aaf3 Install an empty firmware/ directory. 
This reduces the hassle for the users (and distro packages) a bit, you
only need to copy files into there now.
 2011-01-20 23:23:06 +01:00
Uwe Hermann a00b530c64 lib headers: Add 'extern "C"' for C++ usage. 2011-01-20 23:00:59 +01:00

Bert Vermeulen 576790ff7b disable MSO-19 specific stuff for 0.1 release 2011-01-19 22:58:09 +01:00
Uwe Hermann c70fce6ba6 Don't install libs and headers in the 0.1 release. 
The library APIs are not yet usable or finalized, so don't expose the
libs for now. Instead, only install sigrok-cli, the manpages, and
the decoders.
 2011-01-19 19:20:44 +01:00
Uwe Hermann 058b70353d Move more non-public headers to sigrok-internal.h. 2011-01-19 01:16:19 +01:00
Uwe Hermann 01bd1ed396 Fix compiler warning. 2011-01-19 00:46:54 +01:00
Håvard Espeland 32c0551ba6 output_vcd: Make timestamp work on 32-bit machine. 2011-01-18 23:17:55 +01:00
Håvard Espeland 94ba4bd689 Sigma: Update set_configuration to reflect API. 2011-01-18 23:12:57 +01:00
Håvard Espeland 7c70c53843 Sigma: Set default samplerate to 200 KHz. 2011-01-18 22:39:46 +01:00
Håvard Espeland 5b5ea7c6d2 Sigma: Only send trigger packet if enabled. 
The Sigma hardware emits a default trigger event.
 2011-01-18 22:24:23 +01:00
Håvard Espeland abda62ced8 Sigma: Never send empty packets. 2011-01-18 22:17:43 +01:00
Håvard Espeland afa8f8449a output_text: Mark trigger at correct position. 
ASCII output does not separate groups of samples with
and must be handled separately.
 2011-01-18 22:14:36 +01:00
Håvard Espeland 6ef7a8cb5d output_text: Fix ASCII edge case. 2011-01-18 22:13:50 +01:00
Håvard Espeland d4f228d094 output_text: Add ASCII output. 2011-01-17 22:56:14 +01:00
Bert Vermeulen b9cc36296b demo driver: support time limit 2011-01-17 02:20:52 +01:00
Bert Vermeulen 574ce4988a refuse to set sample limit under 4 (protocol can't handle it) 
also a bit of whitespace mangling.
 2011-01-17 02:18:02 +01:00
Håvard Espeland b33e7d7058 output_vcd: Emit timestamps as time, not sample num. 2011-01-16 17:55:51 +01:00
Håvard Espeland 08b488b848 output_vcd: Remember samples between packets. 
Fixes two bugs in vcd output:
1) Waveform did not match original input when viewed in gtkwave.
2) No vcd output when using 1 MHz sampling on Sigma.
 2011-01-16 17:34:49 +01:00
Håvard Espeland 88c51afe87 Sigma: Support for decoding partial chunks. 
Samples are stored in chunks and the last samples do not fill up
a complete chunk. This patch adds support for decoding partial
chunks.
 2011-01-16 17:05:14 +01:00
Uwe Hermann 10c471ab13 Fix warnings. 2011-01-16 14:18:26 +01:00
Uwe Hermann d35aaf0256 demo: Use GIOChannels, makes it work on MinGW. 2011-01-16 14:12:52 +01:00
Bert Vermeulen fbf1ff5d22 clean up output_vcd module 
use self-expanding strings, better standards conformance
 2011-01-16 04:34:45 +01:00
Håvard Espeland 98b8cbc17e Sigma: Limit number of edge triggers to 1. 
Actually, Sigma supports 2 rising/falling triggers,
but they are ORed and the current trigger syntax
does not permit ORed triggers.
 2011-01-15 20:01:00 +01:00
Håvard Espeland 31facdd3c5 Sigma: Download samples from partial chunks. 2011-01-15 19:20:31 +01:00
Uwe Hermann ab224f7b61 Initial support for the OLS output format. 
This is the file format for the OpenBench Logic Sniffer "Alternative" client.
Details: https://github.com/jawi/ols/wiki/OLS-data-file-format

This is work-in-progress.
Currently the number of samples is hardcoded to 10000. Also, this will
require a real logic analyzer as input at the moment, and will not yet
work with the "demo" driver.
 2011-01-15 19:05:14 +01:00
Håvard Espeland 9d7ab9ba3b output_text: Allocate more memory for output 
The trigger line was forgotten. Allocate 512 bytes extra.
 2011-01-15 18:24:01 +01:00
Håvard Espeland 9996570987 Sigma: Move sigma state to device specific struct 
Thanks to Daniel Ribeiro for contributing this patch. Some
modifications were done.

Not tested on multiple Sigmas, because of lack of hardware.
 2011-01-15 17:04:21 +01:00
Håvard Espeland 3aa403e858 output_text: Allocate enough memory for output 2011-01-15 16:12:12 +01:00
Uwe Hermann 858fb11c5e Drop unused debug.c. 
Even if we'd use it, it probably belongs into the frontend, not libsigrok.
 2011-01-15 15:57:54 +01:00
Uwe Hermann 484760d1a8 Cosmetics. 2011-01-15 15:57:54 +01:00
Uwe Hermann aa0b6b208e sigrok-proto.h: Sort the prototypes, fix comments. 2011-01-15 15:57:54 +01:00
