Touchscreen presses not detected on versions D/E of STM32F429-Discovery board #80

Describe the set-up

Describe the bug Touchscreen does not respond to any touches.

How To Reproduce

Prerequisite (I think): a revision D or E board of STM32F429I-DISC1.

Optional: First build and run the older version yourself, to see that it works on this newer board

  1. Obtain STSW-STM32138 (STM32F429 discovery firmware package (UM1662) v1.0.3). Unpack the zip.
  2. Open the project from Projects\Demonstration\TrueSTUDIO\STM32F429I-Discovery_Demo\ in the Atollic TrueSTUDIO IDE. (Similarly to step 3 in the next subsection - File → Open Projects from File System..., etc.)
  3. In Project Properties, C/C++ Build → Settings → Tool Settings tab → C Compiler → Symbols, change USE_STM32F429I_DISCO_REVC to USE_STM32F429I_DISCO_REVD. (Per stm32f429i_discovery.h, USE_STM32F429I_DISCO_REVD : for RevD or RevE boards.)
  4. Build, load, run. (Find it at Projects\Demonstration\TrueSTUDIO\STM32F429I-Discovery_Demo\Debug\STM32F429I-Discovery_Demo.elf.) It appears to be the same firmware that was loaded out-of-the-box. Touchscreen works as expected.

Build demo firmware from this repo to produce the problem

  1. Clone this repo
  2. As hinted by this readme, obtain STemWIN-MW version 5.44.40. (Note, the later 5.44.70 does not include the library files for STM32F4.) Extract the STemWin zip, and copy the contents to the Middlewares/ST/STemWin/ subdir in your working copy of this repo.
  3. Import the project as follows. In Atollic TrueSTUDIO IDE, do File → Open Projects from File System.... Click Directory...; navigate to the Projects\STM32F429I-Discovery\Demonstrations\STemWin\SW4STM32\STM32F429I-Discovery\ subdir of your working copy of this repo. Click Finish, and OK the conversion. image image
  4. Build the STM32F429I-Discovery project.
  5. Use e.g. STM32CubeProgrammer to flash the resulting STM32F429I-Discovery.elf onto the micro. (Find it in the working copy under Projects/STM32F429I-Discovery/Demonstrations/STemWin/SW4STM32/STM32F429I-Discovery/Debug/.)
  6. If prompted, use a pointy object to calibrate the touchscreen.
  7. Observe the application at the homescreen. Try and get the touchscreen to respond to any presses; it doesn't.

Suspected problem

As pictured below, the BSP in the old demo firmware has been updated to account for later board revisions (D/E). The firmware in this repo has not.

Additional context I believe this STM32CubeF4 repo utilizes an old version of the STM32 BSP, namely v4.0.1.

The old demo firmware (STSW-STM32138) appears to be based on something even older.

This repo has many demo and applications; the old demo firmware has less, and is based on older code. An update here would be useful.

Screenshots (None to add)

bmcdonnell-fb commented 3 years ago

When I apply the board-rev-specific changes from the old demo firmware to this repo, it responds as expected for a minute or so, then the app seems to hang.

EDIT: I added USE_STM32F429I_DISCO_REVD to the project symbols, as with the old project.
