darrylring opened a new pull request, #20937: URL: https://github.com/apache/nuttx/pull/20937
## Summary Clone the capture support from the STM32H7. Once again, this should be as close to the H7 port with only the necessary changes to the H5. I know @raiden00pl is working on unifying and commonizing the STM32 code, so don't want to make things harder. There are some bug fixes and improvements that can be made, but I think it's best to handle those separately. **Note: there's an off-by-one error which causes the returned values to be slightly wrong. This is one of the bugs that will be fixed separately.** ## Impact No impact to existing users, since this is a new feature. ## Testing Testing on the NUCLEO-H563ZI using the `capture` config, with https://github.com/apache/nuttx/pull/20936 and the related `nuttx-apps` applied, and the `cap` example app: <img width="1024" height="600" alt="image" src="https://github.com/user-attachments/assets/8a156f25-f0e8-409e-b309-4a633d513018"; /> ``` nsh> cap -n1 cap_main: Hardware initialized.
