Recently in the toss Raspberry Pi, at that time also did not pay attention to, look at the price, bought Mercury network MW150US Ultra-small 150M wireless USB card. But the tragedy was to use iwconfig and not recognize the wireless card But with lsusb words can see MW150US with is Rtl8188eu chip, search on the network, finally found a solution 1. first download the latest Linux kernel for compiling and installing, refer to Http://www.raspberrypi.org/d

Recently, a lot of time in Arm9 s3c2410a ran a NetBSD3.0. Refer to some information on the Internet, especially a Korean website (do not understand Ah, Shingwen), I recorded the process in detail, to the AIDS enthusiasts. The whole process is very simple! I think the reason is that NetBSD is a complete OS. The following is a detailed description of the process (due to NetBSD itself excellent build framework, so the steps are not much, I can do is to say more details, say wordy, ah ~) Producti

seemingly complex problems in the world to be resolved. For example, the "what is the relationship between mobile chip dealers" mentioned here is a very difficult bone to chew.What is the relationship between the Apple A5 processor and arm made by Samsung ...If we use arm as a solution provider for IP core, Samsung, Nvidia and arm are partners who can produce different SOC chips under arm's authority, and TSMC is the factory of the production of SOC

1-hour multi-thread structure application Generally, various control systems used by single-chip microcomputer have various interaction processes such as field data collection, control output, working status detection, and data transmission; the mismatch between the response speed of various peripherals and MCU is an important factor restricting the overall performance of the system. In the face of this interaction bottleneck, the use of time-based mu

My view of single chip microcomputerRecent health is not good, look back on such a few days to walk, now think, also to summarize the time. I have been in the field is very bad, a person, talking people do not have to work a person, sleep is a person. Very lonely. Of course it's a big part of the reason. I am a person who is eager to be loved, but a long time without. Now some of the professional Learning summary summary, in the future to see the youn

technology, including 70 NM evolution to 50 nm, and then evolve to 40 nm or 30 NM process technology, mobile phone customers will also have to redesign, but semiconductor products every 1 years of technology will be new, memory problems also drag on the speed of the introduction of mobile phones, So, like eMMC, the concept of wrapping all the memory and control chips that manage NAND flash on 1 MCP is becoming increasingly popular.eMMC design concept, is to simplify the use of memory in the pho

said ashamed, has always been, in school is also a lot of things, but instead of 51 single-chip computer This basic thing did not seriously to do, at the beginning of self-study 51 not one weeks, and then to Freescale 16 single-chip machine up, so that 51 has not thoroughly made a clear. is not as good as I know s12 monolithic computer what piece of RAM Ah, flash size Ah, instead is 51 not sure answer OH.

Analysis on the attack technology of Single Chip Microcomputer According to the current integrated circuit development technology, there are four main techniques for attacking single-chip microcomputer: (1) software attacks This technology usually uses processor communication interfaces and uses protocols, encryption algorithms, or security vulnerabilities in these algorithms for attacks. A typical case of

Today, the circuit diagram of SD card module, found that the operating voltage of SD card is 3.3V, so need to use voltage regulator chip to convert 5V power supply to 3.3V voltage, so a little bit about the voltage regulator chip data We choose the voltage regulator chip is asm1117-3.3, encapsulated as SOT-223 But in the drawing of the schematic diagram of the

This paper mainly discusses the STM32 of conventional chip capacity and the difference between large and small capacity of STM32 chip. The STM32 large capacity chip is a chip that includes up to 512K bytes of flash memory and 64K bytes of SRAM for large capacity. STM32 small capacity

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
