How the online programmable ISP technology is applied to the LED controller
August 03, 2020
What I want to talk about today is how the online programmable ISP technology is applied to the LED controller , and how to make the led controller develop a leap.
First, ISP (In-System Programming) technology refers to online programmable technology, which means that blank devices on the board can be programmed into the end user code without removing the device from the board. The device can also be erased or reprogrammed using ISP.
The traditional programming method, such as the important part of the single-chip system on the led controller, for example, if you want to program the microcontroller, you must first remove the microcontroller from the board, then put it into a dedicated programmer for programming, and finally Put it in the board again for debugging.
It can be seen that such a development step has the following disadvantages:
1) Frequent insertion and removal of the chip, which easily damages the pins of the chip, and does not adversely affect the maintenance of the led controller.
2) If the program is frequently debugged, the program must be repeatedly inserted and removed, which greatly reduces the speed of developing the flashing effect of the led lamp.
The application of online programmable ISP technology to the led controller is the use of the microcontroller. For example, the LED controllers produced by Qijing Lighting Technology are all based on the online right-programming ISP technology, so if the customer needs what kind of effect, we only need to write freely through the computer, and apply the online programmable The ISP technology MCU can realize different flickering effects through online, which can better meet the needs of lighting engineering customers.
