The software for PFSA145 APPR.3KVA 3BSE008843R1 chip can be written using the programming software keil uvision4. Keil uvision4 not only provides good support for the Cortex-M3 kernel, but also makes configuration and use more convenient. It also includes firmware library functions for STM32. The software of tension control is the soul of the entire control process, and in a reasonable hardware circuit, it dominates all control processes. When the chip is powered on and working, we must initialize the system clock and some required peripherals. Then, the input, output, and display modules are controlled in real-time using a time slice rotation method.

PFSA145 APPR.3KVA 3BSE008843R1 initialization is to prepare the chip for normal operation. Firstly, the system clock needs to be initialized, doubling the operating frequency from 8 M (external 8 M quartz crystal) to 72 M, then initializing the read and write permissions of the internal FLASH, and finally enabling the use of external clock on the bus. Enable peripheral timer 3 and enable PWM function.
