To reduce the ripple of the switching power supply, efforts should be made in the following three aspects:1. Energy storage inductor. The larger the Q value of the energy storage inductor at the opera...
I wrote a Bootloader program based on LPC2104 in the ADS environment. LPC2104 has an example program for IAP to erase FLASH, but there is a problem. It cannot erase FLASH. Whenever it is erased, it wi...
A program runs very smoothly when running in simulation, but it is not smooth after downloading to FLASH. I tested the IO port and found that the same code runs twice as slow when running in simulatio...
