Hello World! I am Victor Tagayun.

I'm hosted with GitHub Pages and this is my Web page.

Yeah, yeah, yeah, I know... it's not a good looking web page and possibly not searchable by Google. Just wait for the on going upgrade to Jekyll or Hugo (I haven't decided on which theme to use yet).

If you have some ideas, ping me and let me know.

A - Interesting Projects / Project Highlights - Arranged according to my Interest / Preference

A01. DSP (FMAC - Filter Math ACcelerator) FIR (IIR is a work in progress) Low and High Pass Filter, "Real-Time" processing

A02. DSP (ARM CMSIS Library) "Real-Time" FIR Low /High pass filter processing (lacking documentations)

A03. DSP (FMAC - Filter Math ACcelerator) Low and High Pass Filter, bulk/batch processing

B. B is for "BUGS". I caught some bugs, lol... and solutions / suggestions to other problems

B01. CubeMX Bug - HRTimE produce wrong code and does not interrupt

B03. CubeMX Bug - CubeMX does not produce the code for the reset source for HRTIMF1

B04. My mistake - P-Nucleo-IHM001 Motor Not rotating

B05. My mistake - ADC DMA using HRTIM as trigger don't have any values

B06. Better Solution - Changing ADC Channels in Injected Ranks

B07. Suggestion from others - HAL_HRTIM_IRQHandler duration is very long
