Don't know why this was never implemented. https://github.com/raspberrypi/pico-extras/blob/ccd88d320f6d759d102cf65a1345d06f1d730f32/src/rp2_common/lwip/lwip_arch.c#L12
If: * routine scanvideo_begin_scanline_generation is called with block = false, * there are no available buffers on shared_state.free_list.free_list * and PICO_SCANVIDEO_LINKED_SCANLINE_BUFFERS is true then at line 1092 of scanvideo,c: *...
Especially when doing a longer async transfer, it can be useful to start reading it before it has finished. This change allows the user to read the number of blocks...
PPP can be enabled in `lwipopts.h` and when disabled it does not affect the binary size.
This would set a bunch of build defines as an example of removing a bunch of runtime support you don't necessarily want when you are looking for every last ounce...
Hi, Some links in [README.adoc](https://github.com/raspberrypi/pico-extras/blob/master/src/common/pico_scanvideo/README.adoc) seem to be broken: 1\. Line 9 ```https://github.com/raspberrypi/pico-playground/scanvideo/mandelbrot[mandelbrot]``` 2\. Line 64 ```https://github.com/raspberrypi/pico-playground/scanvideo/svideo_minimal[scanvideo_minimal]```
Now that lwIP has been integrated into [pico-sdk](https://github.com/raspberrypi/pico-sdk/tree/master/src/rp2_common/pico_lwip) itself (as part of the Pico W functionality), _perhaps_ it makes sense to remove it from [pico-extras](https://github.com/raspberrypi/pico-extras/tree/master/src/rp2_common/lwip) ? And for the lwIP-related...
I need to produce VGA from UART input (yeah, just a terminal emulator). However pico_scanvideo_dpi took both UART0 and UART1 pins. Can I relocate the output pins of the vga...
