PASTE OUTPUT HERE

If your problem is running the binding please past the code you are using below.*
I need to see ALL of the setup code exactly as it is being ran.

PASTE CODE HERE

**Exact make and model number of the MCU that you are compiling for or the firmware is running on. **

• Make: PICO
• Model: 2w

For ESP32 MCU's The PSRAM and FLASH SPI type, quad SPI or octal SPI.

• PSRAM: quad OR octal
• FLASH: quad OR octal

I need to know the OS and OS version of the machine that compiled the binary. If using a VM then I need to know the OS and OS version the VM is running. (WSL == VM)

• OS: [e.g. iOS] Fedora 43

do a fresh clone of the repo and try it again.

I have fixed above errors. Have a look here:
Could you try and let me know, if it works for you, please.
I have also prepared an i80 driver and do some testing at the moment. Hope to be able to send a pull request in a couple of days. After that I plan to work on a RGB driver. But that most likely will need PSRAM, as the frame buffer eats to much of the 520 kB RAM of a PICO2.

That's awesome that you are working on getting the bus drivers going for the RP2040.

But... I don't want you to have to redo work with the drivers.

Now that the ESP32-P4 is supported in MicroPython the MIPI DSI drivers I have written for the ESP32 are going to be able to be used. The reason why this actually is going to impact you is because of software rotation of the frame buffer data.

I would love to have input and help if you are willing to come up with a way to go about doing this so it is portable and would be available across different MCU's. I also want to add the software rotation so it is able to be used across all of the available bus types.

Right now the software rotation is only available for the ESP32 when using an RGB bus connection. The way I went about it is probably the fastest running code for the ESP32. This is because the workload is done by 2coresinstead of 1. so while rotation of the data is being done LVGL is able to render to a second frame buffer. It also allows using partial frame buffers with LVGL instead of using direct mode which is where LVGL renders full frame buffers.

So work doesn't need to be done multiple times an overhaul of the bus drivers needs to be done to add in that software rotation in which doing things like byte swapping and dithering can also be added to improve the speeds when needing to perform multiple operations at the same time, like adding dithering and byte swapping. Only a single iteration over the frame buffer data would need to be done to perform both operations. any combination of software rotation, dithering and byte swapping would be able to be performed in a single iteration over the buffer data.

[kdschlosser]

I know that some MCU's have requirements for using different bus types. like the pin assignments have to be in a specific order and they have to be specific pins. This should not be an issue but if the pins given to the driver do not meet those requirements then the driver should fall back to using bitbang if available and maybe outputting a message letting the user know that they would have better performance if they connected the pins a different way.

I don't want to have a bunch of different bus drivers available for the same type. IE.. having one class for bitbang and another for hardware. The user should no have to know which one they should use. It should automatically be selected based on the parameters that are being handed to the constructor of the driver.

[hemonu]

Thanks for quick your reaction and feedback.
My level of expertise in Micropython and LVGL for sure is far beyond yours, so I want to go in small steps, please.
Let me start with your second remark. I think lvgl_micropython is your project and I leave it up to you, how the structure, level of automation etc. is designed. I would like to have a bit of written guidance, how the interfaces are. This issue is most likely not the best place for further communictaion. If you are ok, I can start a small questionare inside Discussions , which you can answer. Or you let me know your preferred channel for communication.

First step for me was, to get rp2 port compiling and I did therefore a bit of debugging in your code inside extmode/lcd_bus/common... and in the machine_spi driver. I agree, that we need to align on the fuctionality of constructor in there. I followed the examples in the Readme and create first a SPI device and feed that into the lcd_bus constructor.

So I think first step should be just to get SPI displays running again. Do you want to do that yourself or should I sent a pull request for that?

After that I left the bitbanging code for i80_bus aside and worked on this bus with the help of the PIO hardware. It's running for my 16 bit display, but I still have to adapt to an 8 bit bus. Speed is even better than with my 16 bit ESP display!

So I think next step should be, to go back to your bitbang code and make it compile and run, before we decide how to integrate faster code again.

Both hardware SPI and PIO use have restrictions in the choice of pins! But for commercially available products I have seen that they respected that in their design. And if someone does the wiring himself (like me) it would be stupid not to follow those rules.

For RGB bus and maybe DSI later, I believe a) bitbang is not an option and b) PSRAM is a must. That means it only can be achieved with an RP2350. I have ordered two Waveshare RGB displays and a few PSRAM chips, which I can solder onto the display. They will arrive second half of december. So I should have hardware early next year. So we will have enough time to discuss the interface for RGB.
For software rotation I will need the frame buffer in RAM, so at the moment that's out of reach for me. The PICO DMA controller can do byte swapping on the fly during each transfer, even on the same buffer for input and output. I did a small test program in python and it does 1000 byte swaps on e.g. 480*320/10 color pixels in 170 ms. I thinks that's not too bad ;-)

P.S.: I will be travelling tomorrow ...
