I developed a small project on sampleapp before, and used serial port input to control the change of LED, but I found that I could not get the correct result. The serial port debugging assistant did n...
I wrote a section of SPI driver code today. The board uses SPI to operate a FLASH. MPC is the master and FLASH is the slave. Below is my code, which is mainly the initialization of some registers. Thi...
Now ce6.0 has connected to the printer via bluetooth, I don't know how to send the print command, as long as it can print text. The printer is tsc m23 portable, the bluetooth port is com9. Thanks for ...
Conduction loss is caused by the parasitic resistance of the device hindering the conduction of DC current in the DC/DC converter. Conduction loss is directly related to the duty cycle. When the MOSFE...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer
