I am currently debugging a three-phase sensored hub motor based on FOC2.0 control. Now the motor can run smoothly at a faster speed, but under low-speed control, the motor torque is small and unstable...
I received the board yesterday. I ran more than 10 miles to the courier to pick it up. Then I went to the Internet cafe to download the CD and information. I kept downloading until dark. The three lar...

My board is connected to 6713 and FPGA through HPI port. Now I want to transfer a frame of image from FPGA to SDRAM outside 6713. I read the HPI datasheet and wrote the program according to the steps ...
As shown in the picture, this is the display effect of a 7-inch screen. There is a black line between the line color and the green color, but my driver only gives red and green colors. I looked at the...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer
