Most NXP MCU's has an ISP pin which (when pulled low) can is used to cause the MCU into enter a bootloader on reset.
For example on Lpc17xx the is P2.10 and on lpc11xx and lpc13xx it is P0.1.
Always ensure so you had a 10K to 100K Ohm pulling up resistor on the ISP pin, otherwise is unlikely to being able to ma Ke a successful debug connection.

The recent launch of the anti-beauty app Primo in Japan may make you feel overwhelmed. In fact, this anti-human application, you can also write, but must understand some of the technology, is computer vision. At present, the computer Vision Library includes FASTCV, OpenCV, JAVACV and so on.Relatively speaking, OpenCV is a more mature visual library, it contains the Harris, SURF, SIFT, fast and other algorithms, support the object-oriented C + + API, and can be optimized for different hardware, s
says there is no guarantee to support the K JVM in the future, it will develop new, higher-performance J2ME virtual machines instead, but since Kjava appeared earlier, many of the early mobile gaming software have assumed K JVMs as the standard for J2ME virtual machines, so there is a large number of Kjava mobile gaming software available, and continue to develop with Kjava. Japan's mobile gaming software, in particular, is based on Kjava because of its early development (like what Docomi, Japa
How many cores do you have on your phone? This is one of our most frequently asked questions when comparing the two phone differences. The number of CPU cores is indeed an important indicator of the performance of a mobile phone, but it is not the most accurate indicator.Take the most common Qualcomm Snapdragon in the market, for example, in the entire "processor", the CPU portion only accounted for 15% of the chip area, the other 85% is the image Pro
take on high-end models, and will undoubtedly lower its brand appeal.And in the fourth quarter of 2014, MediaTek has shown a downturn, which may not be an accidental "mistake". With Qualcomm in the low-end market to introduce more cost-effective 64-bit chip-there are many domestic handset manufacturers on the thousand-dollar model, Intel continues to exert force, the mobile phone chip market will also usher in a more brutal competition. It is inevita

as the second baseband supplier outside Qualcomm in 2015, so Apple has no need to invest in baseband technology, rather than putting sensors in areas that bring more features to mobile phones. Another investment chip to bring a huge return on the brand is Huawei, and Apple into the chip field to the application of processor-based, Huawei HiSilicon is prominent in the baseband or SOC development, 2014 Huawei relies on the unique Kylin 920 processor se

Ideas repeatedly stated that their goal is to use industry-standard technologies, this usually means running the Linux operating system on the x86 hardware.
However, Norm Fjeldheim, Qualcomm's chief information officer, decided to abandon the migration from Solaris to Linux. Qualcomm does r

Different logs in Android are written to different devices, with a total of/dev/log/system,/dev/log/main,/dev/log/radion, and/dev/log/events four types. Where default LOG.V is written in/dev/log/main. The slog is written to the/dev/log/system.When we use Logcat to catch daycare, we can specify buffer to request different ring buffers (' main ', ' System ', ' radio ', ' Events ', the default is "-B main-b System"), Because the Android log system maintains multiple loop buffers for log messages, a
