transferred using Receive interrupt and stored in RxBuffer2 then compared with the sent ones and the result of this comparison is stored in the "TransferStatus2" variable. 按照意思无非是串口传输的数据和DMA传输的数据进行比对,然后返回状态,程序比较简单,很多地方我加了注释。 /*** (C) COPYRIGHT 200...
If you want get a callback HAL_UART_RxCpltCallback() for each character, in this case, you have to call the HAL_UART_Receive_IT() function (w/ Size parameter = 1) before each receiving character.Hope that can help you, to have insight into the UART receive in interrupt mode.Regards...
STM32的can总线实验心得 (一) 工业现场总线 CAN 的基本介绍以及 STM32 的 CAN 模块简介首先通读手册中关于CAN的文档，必须精读。STM32F10xxx 参考手册Rev7V3.pdfhttp://www.mystm32.com/bbs/redirect.php?tid=255&goto=lastpost#lastpost需要精读的部分为 RCC 和 CAN 两个章节。为什么需要精读 RCC 呢？因...
2) TX polling, RX interrupt, SCE interrupt --> If I start the execution of my program without CAN BUS problem, I don't receive SCE Interrupt but I see that ESR register change its value (it signals the correct problem on the CAN line). Can someone help me? If you need some more ...
We will set up a code in which STM32 Blue Pill will echo back the received bytes to the sender using UART RX interrupt. The code will echo back whatever it will receive on the Rx pin to the terminal. In other words, whatever you type on the serial terminal, it will be sent to the...
