Is it OK to cast a *uint_16 to a *uint_32 and pass it to Start_DMA? Does the function understand that the buffer is really only 4 bytes and not 8 bytes?
@steppeschool3629 Ай бұрын
in that case, I guess you need to specify the memory width to 4 bytes, not 2 bytes.

Does the stm32f103c8 "Blue pill" support the arm_math library?
@steppeschool3629 Ай бұрын
I am afraid it does not support
@kamarmeredow7644 Ай бұрын
Thank you for the video. I tried to use this dsp lib with my stm32f103c8t6 cortex m3 with clock speed 64mhz. But i could not install it because bluepill has only 20kb. I wrote recursive fft code myself. but it took almost 70ms to finish and i lost some values from adc. sampling rate was 8khz. and window size is 128 or even with 64 it was still slow. i think arm dsp uses some kind of hardware accelerated things to make the calculations much faster for example in 1-2ms. But i could not use it as bluepill has only 64kb of flash. What can you suggest? Appreciate that thanks.
@steppeschool3629 Ай бұрын
The easiest solution would be to upgrade your microcontroller. Try more powerful microcontrollers, such as STM32F4, STM32L4, etc. They are not expensive and you can easily implement FFT.
@kamarmeredow7644 Ай бұрын
@@steppeschool3629 Hi. Thank you for the answer. Yes i had also F407 with 512kb of flash. But i wanted to try it with 64kb. Because i saw someone got fft working even with atmel processor with good performance. In the end i wrote my fft function with float type which took 70ms to calculate which is very slow. There is no fpu in bluepill. And after working 2 days i rewrote my functions in fixed point numbers and got it working. Fft took 3-4 ms for calculation, flash usage is 34kb with whole code.

Hi mate, really appreciate for your valuable content. It is really helpful to understand the concept and the flow is just superb! One thing to add, in the line: velocity = linspace(0.0,0.1,num_samples); if you would inverse(transpose) that definition the plot at the end would be more sensible which has actual and encoder plots. Prediction step looks incorrect because you create the velocity_encoder matrix as 300x300 instead of 300x1. Thanks again for this valuable post!
