USART和SPI之间的通信 [英] Communication between USART and SPI
本文介绍了USART和SPI之间的通信的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
stm32f10x中USART2和SPI1之间是否可以通信? 我问是因为USART2时钟适用于APB1，而SPI1时钟适用于APB2. 实际上，我可以在USART1和SPI1之间进行通信，但不能与USART2进行通信.
Is it possible the communication between USART2 and SPI1 in stm32f10x??? I asked because USART2 clock works with APB1 and SPI1 clock works with APB2. and in practice i could have communication between USART1 and SPI1 but couldnt with USART2.
推荐答案
无论时钟如何，您都可以与各个外围设备进行通信. APB1和APB2只是时钟源，不应影响通信.
Well irrespective of clock , you can communicate with individual peripherals. APB1 and APB2 are just clock sources and it should not impact the communication.
