M5Stack StickS3 - New Tab5 - driver modules (#516)
Font size set to 18 for 800x480 displays Fix web server dashboard not rendering when sdcard isn't present Added new driver modules - BM8563 RTC - RX8130CE RTC - MPU6886 IMU - QMI8658 IMU - M5PM1 Power Management Chip Applied the above modules to applicable devicetrees. Added new device: M5Stack StickS3 Added new M5Stack Tab5 St7123 variant. ButtonControl changed to use interupts and xQueue, added AppClose action. And some bonus symbols of course, the apps are hungry for symbols.

|
||||
|

“Work” shall mean the work of authorship, whether in Source or Object form, made
|
||||
available under the License, as indicated by a copyright notice that is included

||||
in or attached to the work (an example is provided in the Appendix below).
|
||||
|
||||
“Derivative Works” shall mean any work, whether in Source or Object form, that
|
||||
is based on (or derived from) the Work and for which the editorial revisions,
|
||||
annotations, elaborations, or other modifications represent, as a whole, an
|
||||
original work of authorship. For the purposes of this License, Derivative Works
|
||||
shall not include works that remain separable from, or merely link (or bind by
|
||||
name) to the interfaces of, the Work and Derivative Works thereof.
|
||||
|
||||
“Contribution” shall mean any work of authorship, including the original version

#### 2. Grant of Copyright License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|
||||
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the Work and such
|
||||
Derivative Works in Source or Object form.
|
||||
|
||||
#### 3. Grant of Patent License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|

grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable (except as stated in this section) patent license to make, have
|
||||
made, use, offer to sell, sell, import, and otherwise transfer the Work, where
|
||||
such license applies only to those patent claims licensable by such Contributor
|
||||
that are necessarily infringed by their Contribution(s) alone or by combination
|
||||
of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
||||
Contribution incorporated within the Work constitutes direct or contributory
|
||||
patent infringement, then any patent licenses granted to You under this License
|
||||
for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
#### 4. Redistribution
|
||||
|
||||
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form,
|
||||
provided that You meet the following conditions:
|
||||
|
||||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
||||
this License; and
|
||||
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
||||
changed the files; and
|
||||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
||||
all copyright, patent, trademark, and attribution notices from the Source form
|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices
|
||||
that do not pertain to any part of the Derivative Works, in at least one of the
|
||||
following places: within a NOTICE text file distributed as part of the
|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of
|
||||
the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide
|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
#### 5. Submission of Contributions
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for
|
||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||
#### 7. Disclaimer of Warranty
|
||||
|
||||
Unless required by applicable law or agreed to in writing, Licensor provides the
|
||||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,
|
||||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
||||
solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of
|
||||
permissions under this License.
|
||||
|
||||
#### 8. Limitation of Liability
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||
accepting any such warranty or additional liability.
