Has anyone done multi-point temperature measurement with DS18B20 single bus? I can read the temperature of each DS18B20 by serial number matching, but when two DS18B20s are connected together, some of...
I am currently working on a project to directly operate the SIM card using an STC microcontroller (basically compatible with 51). I am using the KEIL programming environment. If any expert has a progr...
Have you ever used these two chips? I am using it to convert the 5:6:5 format display signal into a differential signal and send it to the LCD display. However, this chip has 18 input data pins, which...
The usage of 89S51 watchdog function is as follows: In the initialization of the program, write 01EH first and then write 0E1H to the watchdog register (WDTRST address is 0A6H). The watchdog can be ac...
Back to the old business, porting 5.0BSP to 6.0, it was relatively smooth, but I can't get past the USBFN driver. Client uses serialusbfn.dll. Can you help me look at my print information to see if yo...
