SPI - slave

I am new to programming FPGA's in VHDL. One of my starter projects is to write VHDL that will receive a SPI message from my Raspberry Pi, that will then produce a PWM with the duty cycle set from th...

I am working to develop a larger project, making BMS and other useful electronic controls with low cost parts. My goal is to control a buck-boost board like may be used in regenerative braking or other green energy projects. Of course, this is just 1 piece of a larger puzzle, you can see here

I have a lot of work to do, hoping to get through this learning curve ASAP, which is kind of hard without the funding, technical ability, etc... but, each step 1 at a time

Just a quick update. I have figured out to use the Signal Tap II Digital Analyzer provided on Quartus II. I now receive SPI messages, and produce a PWM output based on received message. I would like to learn more about boundary scans, creating DMA like labview does with their single board RTOS

and to start will look into a ADC to gather data now. I am very interested in the NIOS II, and the long road ahead as I continue learning better techniques including multimedia and RF comm..

I thank you for providing a great learning material (Cyclone II - <$30) at a price I can afford
