The buffer size for USB endpoints was previously limited by the endpoints buffer stride, which is 128 bytes * 2 for isochronous endpoints and 64 bytes for bulk transfers. According...
The lwip submodule was removed in https://github.com/raspberrypi/pico-extras/commit/5e594d417d10adc341eb9a884810022f2f6ca5cc so there's now no need for the `.gitmodules` file to exist.
It seems that the `pico_audio_i2s` library intermittently breaks the standard USB stdio implementation, resulting in no communication either way between the pico and the USB host after a short time...
Most of the headers are wrapped in line such as: ```cpp #ifdef __cplusplus extern "C" { #endif ``` and the associated closure - see this as an example: https://github.com/raspberrypi/pico-extras/blob/master/src/rp2_common/pico_audio_i2s/include/pico/audio_i2s.h#L23-L25 this...
This Pico library provides a way to store WiFi hotspot details in Flash and connect automatically, avoiding the need to specify build-time flags such as WIFI_SSID and WIFI_PASSWORD, as is...
If you include sleep.h first you get a compile error as hardware_alarm_callback_t is not defined. Fix this by including the appropriate header. Fixes #89
I am pretty new to C so this might be stupid. I am using a RP2040 and I am trying to go dormant. When using `sleep_run_from_xosc` it complains that `hardware_alarm_callback_t`...
I needed a few extra gpio pins, so reduced the color depth by adding some definitions to `CMakeLists`: ``` add_definitions( # -DPICO_SCANVIDEO_48MHZ=1 -DPICO_SCANVIDEO_COLOR_PIN_BASE=0 -DPICO_SCANVIDEO_COLOR_PIN_COUNT=12 -DPICO_SCANVIDEO_DPI_PIXEL_RSHIFT=0u -DPICO_SCANVIDEO_DPI_PIXEL_GSHIFT=4u -DPICO_SCANVIDEO_DPI_PIXEL_BSHIFT=8u -DPICO_SCANVIDEO_DPI_PIXEL_RCOUNT=4 -DPICO_SCANVIDEO_DPI_PIXEL_GCOUNT=4 -DPICO_SCANVIDEO_DPI_PIXEL_BCOUNT=4...
It'd be great if someone could document how the timing parameters are set up. I added the 640x400 mode per http://www.tinyvga.com/vga-timing/640x400@70Hz since that aspect ratio is useful for me. It...
