According to the DATASHEET of PXA270, I turned on the clock of the power management unit, set C7 of the coprocessor cp14, that is, PWRMODE[VC]=1, and sent a voltage change command to the power chip th...
After DHCP fails, the system will use AUTOIP to configure the IP. I want it to use STATIC static IP after DHCP fails. I have tried to configure lwipopts.h to turn off AUTOIP, but it seems that it will...
When I opened the watchdog in the LM3S811 example for the first time, an LED light flashed after running. I wanted to create a project myself, but after porting watchdog.c to the new project, I couldn...
I made a capacitor-step-down power supply to drive the board. Although it works normally, voltage changes often occur, which burns the chip. Which senior can give me some advice? I'd be grateful. . ....
