As my lcd is SPI driven so which parameter should i change to increase the frame rate and drop the resolution

Thank you sir

The increase in frame rate by modifying the resolution needs to consider various factors. Resolution impacts model input and output, camera capture, and more. This isn't a problem solved by a simple setting adjustment.Please carefully read through the source code and understand the relevant knowledge; all the answers lie within the code and materials. If you lack an understanding of the code and related technical knowledge, then we cannot provide any assistance.

In response to this issue, we have already proposed a detailed solution. Once you thoroughly comprehend the screen control methods, the relationship between SPI screens and framebuffer devices, you will naturally be able to solve your problem independently.

Thank you sir for such an extensive support,

Sir if ypu could please repost
"In response to this issue, we have already proposed a detailed solution. " it will be highly helpful...

In the meanwhile i am going through the code and materials

Thank you in anticipation

1.As per previous discussion, I want to enhance my video fps and make it very smooth and real, now it is buffering and slow

2.I wanted to increase my camera focus area so that it can cover most of the faces.

Thank you for you input very much

1. If you need higher fluidity, you may have to consider sacrificing resolution. However, the model's input size is 640 * 640. If it's smaller than that, enlarging the image afterward could actually affect efficiency. Another direction for improvement is the image display process. Consider using DMA to transfer images to the SPI screen, or using mmap to operate the screen as a framebuffer device. Both of these methods have been mentioned in previous answers and can be tested accordingly.

You might have misunderstood my intention. What I referred to as a solution is the answer provided earlier.

Thank you sir,

I have tried the first with lowering resolution. But no improvement.

If you give a link for image processing or nmap images processing in online, i will independently change it.

Thank you sir

Respected Sir,

Your last suggestion, by memory organization I somehow enhance the fluidity of LCD,

Please suggest a link or method for DMA to transfer images to the SPI screen so that i can explore and do the solution for my own

Thank you in anticipation

We haven't conducted any relevant tests and can't provide assistance.

Respected Sir,

Thank you for your input, I will try to fine tune my code for good frame rate,and further operation.

Please in the meanwhile if you could have any solutions please let me know
