How to achieve get_time() without reading time CSR #6
Description
1、I want to implement video_write function, but I can't find the pointer to framebuffer. I have read wiki and manual carefully, but I fail to find the answer. Maybe I missed something critical. So, where is the framebuffer, or which document should I seek for it.
2、I use the getchar function in your riscv-probe repo. But I found that some key can't be captured, such as F1, CapsLock, etc. I see that only tohost and fromhost are used in the communication between user and device. So far I have not realized how they work. In order to capture other keys, how could I do?
