multi read and write success \r\n");//USART1_Puts(receive_data);} while(1);} 这里程序流程比较简单:1)配置串口,用作程序的调试输出 2)填充将要给SD卡写入数据的数组send_data。3)初始化SD卡,根据返回SD_Init()返回值确定SD卡初始化是否完成。4)单块读写实验
Hello, I am trying to receive a 9 byte length SPI message with standard Altera SPI slave component in QSys. I need to use interrupts, since I
Package(2) { "SPI0-SupportedDataBitLengths", Package() { 8 }}, SupportedDataBitLengths 属性列出了控制器支持的数据位长度。 可以在逗号分隔的列表中指定多个值。 API 将阻止用户指定不在此列表中的值。 数据位长度在连接描述符的_LEN字段中传递给你的SPB驱动程序(ACPI第6.4.3.8.2.2节)。 可以将这些资...
For reading device id: LPSPI0_transmit_16bits(0xC000); //register at 0x00, first two bits are 1 for 'read' and 'multi-byte read' respectively, can't read multiple bytes though LPSPI0_16bits_read = LPSPI0_receive_16bits(); Solved! Go to Solution.0...

https://community.infineon.com/t5/PSoC-6/SCB-SPI-transmit-and-receive-buffer-size/td-p/277228 Thanks & Regards, Rohan I found myself amidst a conundrum. Meticulously crafting and dispatching the requisite commands, the data I received seemed shrouded in inconsistency and erratic behavio...

* Simultaneously transmit and receive a byte on the SPI. * * Polarity and phase are assumed to be both 0, i.e.: * - input data is captured on rising edge of SCLK. * - output data is propagated on falling edge of SCLK. *
It is up to the master and slave devices to know whether a received byte is meaningful. This may require a device to discard the received byte in a "transmit only" frame or generate a dummy byte for a "receive only" frame. Back to top Basic Connections The four typical SPI ...
