A high precision can be achieved for the 48 MHz clock by using the embedded clock recovery system (CRS). It uses the USB SOF signal, the LSE or an external signal (SYNC) to fine tune the oscillator frequency on-the- fly. System reset sources Power-on reset initializes all registers ...
The SPDIFRX also offers a signal named spdif_frame_sync, which toggles at the S/PDIF sub-frame rate that will be used to compute the exact sample rate for clock drift algorithms. 3.37 Single wire protocol master interface (SWPMI) The Single wire protocol master interface (SWPMI) is the ...
SYNC External sync signal Synchronization source for the HSI48MHz embedded oscillator clock recovery system (CRS). One of the three possible sync signal, see the STM32H7A3/7B3/7B0 reference manual [2]. 1. Typical example: (LSE), ...

正是由于在实模式下直接对物理内存进行读写，非常不安全，所以诞生了新的内存分段的映射方式，其目的就...
我们知道DM368有两个串口,UART0和UART1。但是UART0默认为调试串口,也就是说一般不用这个作为通信串口,此刻UART1就成为了DM368和上位机通信的唯一选择。 官方文档表明,UART0和UART1都已经配置好了,并且不需要修改任何代码就可以直接使用,但是实际操作过程中,保证通信程序完全没有问题的情况下,并不能完成通信。这就...
Seems like you found out that if the cache data is not in sync with RAM when calling DMA (which is accessed using registers this time, so no caching is done right ?), this can lead to mismatch in configuration data and in the end, Ethernet IP is not set to fire the TX complete in...
