From 3e7a09cb0dee0ee04b5c77f427bf89d990ec8d0b Mon Sep 17 00:00:00 2001 From: Dana Conrad Date: Sat, 26 Jun 2021 12:07:11 -0500 Subject: New Port: Eros Q Native What works: - LCD: 16-bit RGB565 - all buttons, including scrollwheel - SD Card - Battery level and charging/not charging status - USB - audio - sample rate switching - HP / LO detect, with "safe" fixed LO volume - LO volume will only be put to user-defined max volume if headphones are not present. - rtc - Plugins build, tried a couple and they seem OK - Bootloader, installable to nand via usbboot What doesn't work: - Dual Boot - power on/off has intermittent, low volume audio click (sometimes it's completely silent, sometimes there's a click) - Audio uses 16-bit volume scaling, so clicking/popping is pretty bad at lower volumes - need 32 bit volume scaling, 24 bit I2S data - USB HID keys not yet defined - no jztool support Unknowns: - Stereo Switch pins: Direction select, AC_DC (probably not even hooked up) - What is the actual purpose of the Stereo Swtich? - How does the bluetooth module connect? "Someday" stuff: - get LCD working at higher bit depth - Bluetooth Change-Id: I70dda8fc092c6e3f4352f2245e4164193f803c33 --- .../mips/ingenic_x1000/erosqnative/adc-target.h | 0 .../erosqnative/audiohw-erosqnative.c | 90 ++++++++ .../erosqnative/backlight-erosqnative.c | 63 ++++++ .../ingenic_x1000/erosqnative/backlight-target.h | 33 +++ .../mips/ingenic_x1000/erosqnative/boot.make | 30 +++ .../ingenic_x1000/erosqnative/button-erosqnative.c | 247 +++++++++++++++++++++ .../mips/ingenic_x1000/erosqnative/button-target.h | 45 ++++ .../mips/ingenic_x1000/erosqnative/gpio-target.h | 71 ++++++ .../mips/ingenic_x1000/erosqnative/i2c-target.h | 31 +++ .../ingenic_x1000/erosqnative/lcd-erosqnative.c | 188 ++++++++++++++++ .../ingenic_x1000/erosqnative/power-erosqnative.c | 110 +++++++++ .../ingenic_x1000/erosqnative/spl-erosqnative.c | 63 ++++++ 12 files changed, 971 insertions(+) create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/adc-target.h create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/audiohw-erosqnative.c create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/backlight-erosqnative.c create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/backlight-target.h create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/boot.make create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/button-erosqnative.c create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/button-target.h create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/gpio-target.h create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/i2c-target.h create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/lcd-erosqnative.c create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/power-erosqnative.c create mode 100644 firmware/target/mips/ingenic_x1000/erosqnative/spl-erosqnative.c (limited to 'firmware/target/mips/ingenic_x1000/erosqnative') diff --git a/firmware/target/mips/ingenic_x1000/erosqnative/adc-target.h b/firmware/target/mips/ingenic_x1000/erosqnative/adc-target.h new file mode 100644 index 0000000000..e69de29bb2 diff --git a/firmware/target/mips/ingenic_x1000/erosqnative/audiohw-erosqnative.c b/firmware/target/mips/ingenic_x1000/erosqnative/audiohw-erosqnative.c new file mode 100644 index 0000000000..7bb985650c --- /dev/null +++ b/firmware/target/mips/ingenic_x1000/erosqnative/audiohw-erosqnative.c @@ -0,0 +1,90 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2021 Aidan MacDonald, Dana Conrad + * + * This program is free software;
