Open the HyperSPI developer repository, we need a page of release versions
(link).
Download the latest driver depending on the board used (Rp2040 / ESP32 / Esp8266) and the type of LED strip.
In my case, I am using an Rp2040 board and a WS2812B tape, so I need to use the driver:
HyperSPI_Pico_ws2812.uf2
We connect the Rp2040 board to the computer using a Type-C cable.
Next, you need to put the Pico board into DFU mode, to do this, press and hold the "boot" and "reset" buttons,
then release the "reset" button then release the "boot" button. In the system file manager you should find a new disk
with name "RPI-RP2"
Drag (or copy) the previously downloaded firmware to this disk.
Pico will automatically reset after booting and within seconds it will be ready for use with HyperHDR.
From this post by the author of HyperHDR, download the current version of the modified firmware
(ссылка).
This message contains links to download the utility for flashing our device, download it
(ссылка).
Open the downloaded program, connect the capture card to the computer.
In the window after connecting the device you should see a green square (previously it was red before connecting).
Click on the "Read" button, then "Save to BIN".
We save the read file with the extension *bin; at this stage we saved a backup copy of the original firmware.
Now let’s download the modified firmware and unpack the file with the *bin extension from the *zip archive.
In the program window, click the "Open File" button, indicate the path to our file, and click "Download".
We are waiting for the process to complete; in the lower corner, after the download is complete, we will see a message about
successful firmware.
At this point, this stage of preparing the devices for further assembly is completed.
