The scope of USB on PIC32MZ silicon USB is quite a complicated protocol. I would like to use this post to explain a few terminologies and concepts that we will…
Why not Harmony First of all, I’m a royal promotor of Microchip’s MCU products for over a decade. From pic24 to dspic33, from PIC32MX to PIC32MZ, Microchip’s MIPS line never…
It used to be pretty straight forward to assign a net to a hidden pin of a component using the right-click property menus. However, this function has been relocated to…
The scope of the OpenRISC project is so extensive that it covers wild range of areas including processor architecture, implementation with register transfer language, simulation tool, synthesis tool, and tool-chain…
