串口通讯，下位机是血压计。也可以连接血压模拟仪，实现自动测试。-Serial communication, the next crew is sphygmomanometer. Blood pressure simulator can also be connected, automatic testing.

基于STM32的脉搏电子血压计（原理图+程序）电子血压计源码，袖带充放气计算脉搏(Based on STM32 pulse electronic sphygmomanometer (schematic diagram + program) electronic sphygmomanometer source code, cuff inflation and deflation to calculate pulse)
