A new device driver always requires HAL ?

Hello, 

 I am new with NIOS II. I would like to ask a general question, does it require to use HAL with each new device ?  Regards, Ran

Yes, We required to use HAL for devices.HAL used to interface between the OS,Drivers,C-Library to different interfaces (EX: UART,SPI,LCD DRIVER). 

Depending on interfaces available on FPGA HAL functions are used.  For more understanding, kindly check following links Overview on HAL: https://www.altera.com/products/processors/design-tools.html Function in HAL: https://www.altera.com/en_us/pdfs/literature/hb/nios2/n2sw_nii52010.pdf  Best Regards, Tzi Khang, Lim (This message was posted on behalf of Intel Corporation)
