Originally, the data transmission function test with the computer had been successful many days ago, but the specific interface was not completed. However, two or three days ago, due to a detail probl...
I use lattice's ECP3 95E, which is a FBGA672 package. The design has a ddr2 sdram controller. The lattice datasheet says that for signals such as DQS , dedicated pins must be used, and they are usuall...
The board has been made for a long time, but I can't find the open line test program for 2530 under IAR760. There is no such program in the 07 protocol stack. If anyone can give me a copy, I will be v...
Abstract: The principle of fast charging is explained. In view of various problems that occur during battery charging, a pulse fast charging scheme with graded constant current is adopted, and the des...
The battery of an electric vehicle can be used for about two hours, which is very inconvenient for users. It is normal to run out of power when going out. If we have a fast charger, we can quickly rep...
