I would like to ask, 1. How is the address of the wince and linux kernels in the memory determined? 2. I am using a 64M NAND FLASH. I want to burn the wince kernel into the FLASH. From which address i...
The servos are MG995 and SG90. Yesterday, I used 3.3V power supply directly, and the MSP430 IO port directly output 20MS cycle PWM to drive the servos. There was no problem except a little shaking. Bu...
My W732 flagship, it says the driver has been found, but when I try to install it, an error occurs. The method in the previous help post is not useful. Someone said it was a USB cable problem, but it ...
I have a Freescale MC13224 development board and a ZigBee positioning project. I know that the distance from the target to the communication node can be obtained through RSSI, but I don't know how to ...
