With the improvement of computer performance and the increasing traffic, traditional local area networks are getting more and more out of their load. The exchange Ethernet technology has emerged, greatly improving the performance of local area networks. A network switch can significantly increase the bandwidth and establish a geographically dispersed network. Each port of a LAN switch can transmit information in parallel, securely, and in real time. It features stable performance, flexible struc

This scheme enables MAC and PHY to be well matched, while reducing the number of kohiki feet, Reduce the

The code is as follows: #include The last time a long current_time;//was measured /*mypro*/ #define LED_1 BIT0 #define SW_2 BIT3 #define Ta1_1 BIT2//ta0.1 hc-sr04 E

3. Interrupt Controller Driver In the Linux kernel, individual device drivers can simply invoke Request_irq (), ENABLE_IRQ (), DISABLE_IRQ (), local_irq_disable (), local_irq_enable () such as General API complete interrupt application, enable, prohibit and so on function. When porting Linux to a new SOC, the chip vendor needs to provide low-level support for that part of the API. The implementation of Local_irq_disable (), Local_irq_enable () is in

Contact SCM has a few years of time, has been focused on how to write some applications on a single chip microcomputer, how to start the knowledge of little, ashamed ashamed ... Today, I have to tidy up a bit, deepen the understanding of the SCM, such as why the definition of the data area of the variable restart the initial value of 0. When the MCU is powered on, it will execute startup. The instructions for the A51 file, I analyzed the instructions

51 single chip microcomputer precise delay procedure (crystal oscillator 12MHz, a machine cycle 1us.)Several precise delay procedures: in the calculation of accurate delay, the most easily overlooked is the calculation of the loop outside the part of the delay,This part does not affect the program in situations where the time requirement is not high.

are parity bits (1/0). The sum of the number of 1 in the data and the number of the test bit 1 should be odd at parity, and the number of 1 in the data and the number of checksum digits 1 should be even when parity. When a character is received, the number of 1 is validated, and if the character is inconsistent, an error occurs during the transfer of the data. Code and checksum The sender sums the data blocks (or each byte xor), resulting in a byte of the checksum character (checksum) appended

51 single-chip microcomputer is capable of output PWM, the trouble of comparison. In this case, an internal timer is needed to implement it, which can be implemented with two timers or with a timer. The method of using two timers is to control the frequency with the timer T0, and the timer T1 to control the duty ratio. The general programming idea is this: T0 timer interrupt let a I0 port output high level, in this timer T0 interrupt in the start Time

1. Logical bank and Chip WidthAfter explaining the external form of the SDRAM, we should have a deep understanding of the internal structure of the SDRAM. The main concept here is the logical bank. Simply put, the internal structure of SDRAM is a storage array. Because it is a pipe-type storage (such as queuing to buy tickets), it is difficult to achieve random access.The array is like a table. You can fill in the data as a table. Like table search, y
