Implementing CIMT Coding with FPGA
I am working on a project recently, which is to use FPGA to realize video transmission over optical fiber. Since ordinary binary code cannot be transmitted in optical fiber, the binary code must be co
Notes on the power consumption test of LM3S5749
A note based on the power consumption test of LM3S5749. It contains some experimental data and a brief introduction to some methods of controlling power consumption.
I plan to fight the PIC32MZ interrupt to the end
I have a bit of obsessive-compulsive disorder and don't want to use harmony. The main reason is that it takes a few days to figure out how to use it, so I write all the interrupts myself. After severa
