In our lives, if you don’t have any “tables†or “loops†on your hands, you will feel Out. Since 2014, wearable devices have emerged like floods, and major manufacturers such as Samsung, Sony, LG, Xiaomi, and Huawei have settled in. The smart bracelet is a wearable smart device. Through this bracelet, users can record the exercise data of daily exercise, sleep, part and diet, and synchronize the data with the mobile phone and tablet. Data guides the role of healthy living.
Recently, our programmers department frequently received questions from customers about the programming of the nRF51822 chip. Knowing the customer's industry background, most of them are developing wearable smart devices. The smart bracelet solution is based on Nordic's nRF51822 chip, which is a microcontroller based on ARM high-performance Cortex-M0 32-bit RISC core. With 256KB/128KB Flash + 16KB RAM, it also has a rich analog and digital peripheral that can interact through the Programmable Peripheral Component Interconnect (PPI) system without CPU involvement. And integrated BLE Bluetooth 4.0 protocol, providing a perfect solution for smart bracelets. They are in urgent need of finding an efficient programming tool to ensure huge shipments.
Faced with such a large shipment, they encountered the following problems in production to seek our help.
1) nRF51822 is used in a large amount, and the cost of using the seat is high, because the adapter is a loss product;
2) There is a risk of leakage of firmware data, to protect intellectual property rights and avoid firmware data leakage.
The P800-ISP programmer provides the perfect solution to the customer's questions. The nRF51822 supports SWD in-circuit programming. It only needs to draw the VCC, GND, SWDIO and SWDCLK signal lines to achieve online programming, saving a large number of adapters and reducing production costs. The P800-ISP in-circuit programmer provides a 4-channel simultaneous operation mode with up to 4x capacity.
The firmware encryption mechanism of the P800-ISP allows the development of packaged projects and firmware and the setting of passwords. After the foundry got the encryption project, it only saw the project and could not see the firmware, thus preventing the firmware from leaking.
Even if the encryption project leaks to the outside, it is difficult to extract firmware from it, greatly reducing the risk of firmware leakage. The characteristics of this model are:
The encrypted firmware is invisible and difficult to copy and extract, reducing the risk of leakage;
The burner does not need to know the specific burning content to reduce the difficulty of operation;
Since the firmware is encrypted, you can safely submit the encryption project to a third party to commission it.
An optional server can assist in the unified management of all company firmware.
It can be seen that the encryption project avoids the risk of firmware leakage in a large program and effectively protects the company's intellectual property rights. With the P800-ISP in-circuit programmer, shipments of smart bracelets are not an issue.
