电源电压1.62-3.6V,电源可选用硬币电池或纽扣电池。系统级节能功能包括32-levelFIFO、内置温度传感器和可编程中断引脚。中断引脚用于检测自由落体、唤醒、活动/非活动、6D/4D方向和单击/双击事件。 信号通过传感器电路耦合后,再经差分前置放大电路、多级放大电路、隔直电路、陷波电路、带通滤波电路,最终可得到有价值、可...
完成前面3步就完成了UART的基本配置,接下来就可以进行收发了, 使用uart write bytes()往Tx FIFO buffer里面写数据,就可以发送数据; 使用uart read bytes()从Rx FIFO buffer里读数据,就是接收数据; 其他的工作由FSM(UART controller’s finite state machine)完成 。 具体的使用可以查看手册上面Running UART Communi...
If you are looking at maximum throughput, you must use DMA TX AND RX channels on 2 different buffers (transmit and receive simultaneously). In the SPI V2 (like in STM32L4), there are FIFO to improve in some cases the throughput even when DMA is not available. HI, I am getting same ...

I believe uart_tx_chars() bypasses the (potentially large) ring buffer in memory and writes as many characters as it can directly into the UART's hardware FIFO. From the docs: Another function for writing data to the Tx FIFO buffer is uart_tx_chars(). Unlike uart_write_bytes(), this...
As data is stored in a first bank of the L 2 cache, the old data at that location is passed through the crossbar switch to a second bank of the L 2 cache that is functioning as a first-in-first-out memory (FIFO). Thus, new data is cached at a location in the first bank of ...
