My target board is ARM920T. The OS customized by PB4.2 can be successfully downloaded to the target board through the network cable and can be started. After exporting the SDK, I used this SDK to writ...
In the picture, the LED is 0.5W/2V, 12 LEDs are connected to 24V, the resistance = 2V*6/250mA*2=24R, right? Then the power of the resistor is 2V*6*250mA*2=6W?
Because the chip resistors used are not s...
I have used KEIL for a long time. When I open a project, there are many historical list records. I specially organized them for your convenience. KEIL history files can be automatically cleared or cle...
