From: Gerhard Sittig Date: Sun, 9 Jun 2019 08:48:21 +0000 (+0200) Subject: brymen-bm86x: retire libusb using driver, has moved to serial-dmm X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=97c8fa70dabaab121a1a2fc1256cf3a1297846f1;p=libsigrok.git brymen-bm86x: retire libusb using driver, has moved to serial-dmm Remove the src/hardware/brymen-bm86x/ hierarchy of source files. Its functionality has moved to the bm86x packet parser and the serial-dmm device driver. --- diff --git a/Makefile.am b/Makefile.am index 0f748f3e..42759739 100644 --- a/Makefile.am +++ b/Makefile.am @@ -250,12 +250,6 @@ src_libdrivers_la_SOURCES += \ src/hardware/beaglelogic/beaglelogic_native.c \ src/hardware/beaglelogic/beaglelogic_tcp.c endif -if HW_BRYMEN_BM86X -src_libdrivers_la_SOURCES += \ - src/hardware/brymen-bm86x/protocol.h \ - src/hardware/brymen-bm86x/protocol.c \ - src/hardware/brymen-bm86x/api.c -endif if HW_BRYMEN_DMM src_libdrivers_la_SOURCES += \ src/hardware/brymen-dmm/parser.c \ diff --git a/configure.ac b/configure.ac index df00ab67..b23d52bd 100644 --- a/configure.ac +++ b/configure.ac @@ -254,7 +254,6 @@ SR_DRIVER([ASIX SIGMA/SIGMA2], [asix-sigma], [libftdi]) SR_DRIVER([Atten PPS3xxx], [atten-pps3xxx], [serial_comm]) SR_DRIVER([BayLibre ACME], [baylibre-acme], [sys_timerfd_h]) SR_DRIVER([BeagleLogic], [beaglelogic], [sys_mman_h sys_ioctl_h]) -SR_DRIVER([Brymen BM86x], [brymen-bm86x], [libusb]) SR_DRIVER([Brymen DMM], [brymen-dmm], [serial_comm]) SR_DRIVER([CEM DT-885x], [cem-dt-885x], [serial_comm]) SR_DRIVER([Center 3xx], [center-3xx], [serial_comm]) diff --git a/src/hardware/brymen-bm86x/api.c b/src/hardware/brymen-bm86x/api.c deleted file mode 100644 index a6c45e3a..00000000 --- a/src/hardware/brymen-bm86x/api.c +++ /dev/null @@ -1,220 +0,0 @@ -/* - * This file is part of the libsigrok project. - * - * Copyright (C) 2014 Aurelien Jacobs - * - * This program is free software: you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
