1 Advantages and disadvantages of the front-end and back-end systems. The architecture of the front-end and back-end systems can be described in one sentence as a large loop, plus interrupts, which fo...
The framework class receives serial port data and passes it to the corresponding VIEW class for processing through messages. However, the VIEW class implements the function of popping up a menu by pre...
I put a GPRS module on the board, SIM508. When I debugged it today, I found that the dial-up under WINCE5.0 always showed "dialing "*99***1#", and then there was no response. After a long time, it sho...
Using DSP to realize the precision expansion of IIR filter Abstract: This paper mainly introduces how to implement extended precision multiplication on TMS320C54X DSP, the basic principle and algorith...
The realization of limited bipolar control in high-power inverter power supply is first recommended. . . I will recommend it when you come for the second time. . . Haha...
When writing a program, IO port PB3 cannot output a high level. I found in the data sheet that PB3 is a debug port, so I remapped GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE); to disable th...
