After reading datasheet for four days, I finally started to write code yesterday. So far, the capacitive screens I have done include ITE, Solomon, focaltech, EETI, and cypress. To be honest, the driver for writing these things is already familiar, but today I still feel it! ATMEL's capacitive screen is the best. The interface for drivers is perfect, and even the object-oriented idea is used! The Atmel driver is really a pleasure. Now you can experienc

Microcontroller(MCU) series of entry-level tools. The custom MCU of cap7 allows designers to transfer from the "ARM7 and FPGA" design to a low one-time R D cost (NRE)
Single ChipSolution: the cost per device is reduced by about 30%, and the performance is improved by 8 times. The static power consumption and working po
Bluetooth 1.2 vs 1.1:
1. Adaptive Frequency Hopping (AFH ):Adaptive Frequency Hopping TechnologyThe main function is to reduce interference problems between Bluetooth products and other wireless communication devices.
2. Extended synchronous connection-oriented links (ESCO ):Extended synchronous link-oriented channel technologyIt is used to provide audio transmission with high QoS, and can further meet the

1. As shown in the following illustration, we go to the computer Control Panel and then find "Add Device".
2. As shown in the following illustration, we adjust to the search status (here, for example, the mobile phone).
3. Then click "Next" as shown in the following figure.
4. The Verification code
A very important feature of Bluetooth is that all Bluetooth products do not need to implement all Bluetooth specifications. To make it easier to maintain compatibility between bluetooth devices, the profile is defined in the Bluetooth specification. Profile defines how a dev
