E (612) uart: uart_write_bytes(1193): uart driver error // a uart_write_bytes() call So the question is, what is the difference between the way printf() uses the UART and the way uart_write_bytes() uses the UART? And how would I configure the UART driver so as to be identica...

首先我们Clone一个UART with DMA的工程,原始工程在MCUXpressoSDK目录boardsevkmimxrt1170driver_exampleslpuartedma_transfer中,我们先看下原始代码: //初始化时钟,PinBOARD_ConfigMPU();BOARD_InitPins();BOARD_BootClockRUN();/* Initialize the LPUART. *//* * lpuartConfig.baudRate_Bps = 115200U; * lpuart...

Solved: Hi, I'm using uart3 interrupt of RT1020 ,i'm using uart3 for rs-485 communication and its speed is 3MBps. Also, I'm using LPSPI4 CMSIS driver
typedefenum{ UartSuccess, UartNoData, UartError, UartNotReady } UART_STATUS, *PUART_STATUS; 常量 UartSuccess 操作成功,例如,如果数据可用。 UartNoData 没有可用的数据,但由于错误条件而不可用。 UartError UART 错误,例如溢出、奇偶校验、帧等。
So I installed, and got an error 10, could not start the device. (This was when using the Micro-USB connector on the CY8CKIT-059.) I uninstalled both the driver for the serial port, and the driver for the CDC device and rebooted. I tried to re-install, and got a Com...
