Point: 1. Serial port and COM port refer to the physical interface form (hardware). TTL, RS-232, and RS-485 refer to the level standard (electrical signal). 2. When connecting to a device, generally o...
I want to use the SPI of STM8S to receive a set of 16-bit data, but everyone knows that the SPI of STM8S is 8-bit. I would like to ask you how to correctly receive this 16-bit data. Please help me. Th...
The last few lines of the map file generated by IAR for my program are as follows: [color=#008000] 9 906 bytes of CODE memory[/color] [color=#008000] 280 bytes of DATA memory ([/color][color=#ff0000]+...
Where can I adjust the order of loading drivers when the device starts? The reason is this: if my WINCE device is connected to the computer with a USB cable, the device will enter the Mass Storage mod...
I use nandflash as a USB disk in winxp on 2440+wince 5, and change default usbdevice to mass_storage. The USB disk can appear in winxp, but wince cannot access the flash disk at this time. This is nor...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
