I am Zhihong Niu, a 2nd year computer science student from China. I am one of the two students selected by Arduino for this year's Google Summer of Code, you can find the other student here.
You can find my proposal here. This is an organization which made up of previous GSoC students who would like to share their experience of applying and passing GSoC. If you find members here interned for the organization(s) you want to apply for this year, feel free to contact them.
This summer I will port FreeRTOS to the new board Portenta H7, and try to allow running arduino sketches on it.
Between June 2, 2020 and September 1, 2020 I will post my weekly report here, if it can help some people, that would be great.
Any questions are welcome.
