tbh I don't quite understand why 'flip' is 90° rotation, but we should only have one source of truth here.

I think the definitions ST77XX_ROTATION_{HORZ_FLIP,VERT_FLIP} are a bit misleading and it is not really clear what FLIP means without trying it. When configuring the display, a number of trials are required to find the correct orientation.
Per definition the display coordinates are defined as
+------> X (ST77XX_PARAM_RGB_CHANNELS)
|
|
|
Y v (ST77XX_PARAM_NUM_LINES)
The X dimension is the smaller one compared with the Y dimension so that it corresponds to the vertical orientation. Usually (at least all displays I know) have the connector at the bottom, i.e. at Y_max.
To get the horizontal orientation of the display rotated by -90 °, X and Y have to be swapped (LCD_MADCTL_MV) and afterwards the new Y has to be mirrored (LCD_MADCTL_MY) which is the same as defined as ST77XX_ROTATION_HORZ_FLIP.

19914: boards: complete SD Card MTD definition for several bords r=benpicco a=gschorcht ### Contribution description This PR completes the MTD definition for the following boards: - `seeedstudio-gd32` - `sipeed-longan-nano` including `sipeed-longan-nano-tft` - `waveshare-nrf52840-eval-kit` - ESP32x boards that have an SPI SD Card interface and use `mtd_sdcard_default` ### Testing procedure Green CI ### Issues/PRs references#19465 Prerequisite for PR #19465 19915: drivers/lcd: support MCU 8080 8-bit parallel mode r=benpicco a=gschorcht ### Contribution description LCD driver ICs usually support - SPI serial mode, - MCU 8080 8-bit parallel mode and - MCU 8080 16-bit parallel mode. This PR extends the LCD display driver API to support the MCU 8080 8-/16-bit parallel modes and implements a GPIO-driven MCU 8080 8-bit parallel mode. The following features are already working locally and will be provided as follow-on PRs for which this PR is a prerequisite. - GPIO-driven bit-banging implementation of the 16-bit mode of the MCU 8080 parallel interface - Enabling the display on `stm32f723e-disco` and `stm32l496g-disco` using the feature above - Definition of a low-level API for the parallel modes using the LCD controller of the MCU - Using FMC for the display on `stm32f723e-disco` and `stm32l496g-disco` - Using LCD controller for the display of `esp32-wt32-sc01-plus` (PR #19917) ### Testing procedure The PR can be tested with PR #19917 on top of this PR. ``` BOARD=esp32s3-wt32-sc01-plus make -j8 -C tests/drivers/st77xx flash ``` The following video shows the test. **Please note** The test is pretty slow because the display has 480 x 320 pixels and the MCU 8080 8-bit parallel interface is realized by a GPIO-driven bit-banging implementation where each GPIO of the data bus is set separately. A follow-up PR will use the ESP32-S3 LCD controller and DMA for this board. This PR just defines the extension of the driver by the parallel interface and provides the bit-banging implementation for MCUs that don't have a LCD controller on chip. https://github.com/RIOT-OS/RIOT/assets/31932013/c1e3e3d7-05d9-4ca5-8fff-9a5eaca50fba ### Issues/PRs references 19919: drivers/st77xx: introduce rotation defines r=benpicco a=gschorcht ### Contribution description The PR introduces counterclockwise rotations for the definition of parameter `ST77XX_PARAM_ROTATION`. It is more intuitive and universal to use `ST77XX_ROTATION_{0,90,180,270}` instead of `ST77XX_ROTATION_{ST77XX_ROTATION_{VERT,VERT_FLIP,HORZ,HORZ_FLIP}`, especially because the orientation of the display may vary with respect to the orientation of the board. ### Testing procedure `tests/drivers/st77xx` should still work, for example: ``` BOARD=adafruit-pybadge make -C tests/drivers/st77xx flash ``` ``` BOARD=esp32s3-usb-otg make -j8 -C tests/drivers/st77xx flash ``` ### Issues/PRs references 19931: boards: fix documentation for GD32V boards and doxygen 1.9.4 r=benpicco a=gschorcht ### Contribution description This PR fixes some small problems in documentation of `sipeed-longan-nano`, `sipeed-longan-nano-tft` and `seeedstudio-gd32` for doxygen 1.9.4 that is used on `doc.riot-os.org`. Doxygen version 1.9.4 doesn't like anymore - single double quotes as symbol for the inches unit in the text - line breaks in `[]()` to avoid exhausting the 100 characters per line. See https://doc.riot-os.org/group__boards__sipeed__longan__nano.html for example. Doxygen 1.9.1 which is part of `riot-docker` container didn't have theses problems 😟 ### Testing procedure Documentation should be fixed. ### Issues/PRs references 19935: boards/nucleo64: fix SPI Arduino mapping for most boards r=benpicco a=maribu ### Contribution description Before, the Arduino SPI mapping for all Nucleo-64 boards was incorrect. With this, the situation improves to the following: - [x] nucleo-f030r8 - [ ] nucleo-f070rb - No SPI buses provided. - [x] nucleo-f072rb - [x] nucleo-f091rc - [x] nucleo-f103rb - [ ] nucleo-f302r8 - No SPI bus at D11, D12, D13 provided - [x] nucleo-f303re - [x] nucleo-f334r8 - [x] nucleo-f401re - [x] nucleo-f410rb - [x] nucleo-f411re - [x] nucleo-f446re - [x] nucleo-g070rb - [x] nucleo-g071rb - [x] nucleo-g431rb - [x] nucleo-g474re - [x] nucleo-l053r8 - [x] nucleo-l073rz - [x] nucleo-l152re - No SPI bus at D11, D12, D13 provided - [x] nucleo-l452re - [x] nucleo-l476rg - [x] nucleo-wl55jc The remaining offenders still need to be fixed, but that is better done one PR at a time. ### Testing procedure - Check if the SPI device provided in the given `boards/<BOARD_NAME>/incude/periph_conf.h` is indeed `SPI_DEV(0)`, or in `periph_conf.h` the correct SPI dev is found - this should be fine for all boards above, except for the unchecked ones or: - run #19932: The SPI test should pass now ### Issues/PRs references Bug found in #19932 (comment) Co-authored-by: Gunar Schorcht <gunar@schorcht.net> Co-authored-by: Marian Buschsieweke <marian.buschsieweke@posteo.net>
