您好，请问我们在使用DMA传输时，用Spi_setupEB把数据长度设置为大于32（64、96、128）的数值，用示波器和逻辑分析仪发现SPI的波形没有了。只有数据长度设置为32是正常的，这是为什么？追加

I have a MR-CANHUBK344. I am using the generic 7-wire JST-GH cable to connect SPI port P1A to P1B so that I can demo the exchange of SPI data locally
我想知道 QSPI 寄存器的相关信息。 TRM 中 QSPI_SPI_Setup1_REG 的[13:12] READTYPE 如下所示。 0x0:正常读取(qspi1_d[1]上的所有数据输入) 0x1:双读取(qspi1_d[1]上的赔率字节输入; qspi1_d[0]上的偶数字节) 0x2:正常读取(qspi1_d[1]上的所有数据输入) 0x3:四路...

Hi all, I am currently trying to replicate the SPI (aka spi0 tegraX1, spi1 Jetson Nano) device tree configuration done in the Devkit to the production SoM with a custom board. Following several threads on this forum …
When setting up for SPI into the PGA112, is the data width (packet size) 8bits, or 16bits? It appears by the data sheet it is 16 bits...but want to be sure Should be SPI be set up for full duplex? (Probably not, as DIO is handled integrated?) ...
