Hello everyone I am Chris, the Field Application Engineer from Nuvoton Technology. Today I will introduce the programming and debugging tool, called NuLink-Gang, and NuLink2-Pro. And I will show you in what kind of situation you can utilize the tools. During system development, Nuvoton provides three IDE interfaces: KEIL, IAR, and NuEclipse for user to develop source code. When programming the Chip, Nuvoton provides ICP programming Tool in PC and the debugger Nu-Link2-Pro for users to perform debugging and programming function. User who uses all of the Nuvoton Nu-Maker boards series can develop through the Nu-Link2-Me debugger and programmer; it’s attached to the board. During the mass-production stage, there are 2 modes for programming the target chip. One is online programming and the other is offline programming. At first, in online programming mode, user can use ICP programming Tool and a Nu-Link2-Pro to program a target chip. Besides, if it needs to program several chips at one times, the Nu-Link Command Tool supports program multiple develop board by several Nu-Link2-Pro. Nu-Link2-Pro also supports drag-and-drop Flash programming. User can intuitively complete the programming action. Nu-Link2-Pro In offline programming mode, user can pre-store the programming file in SPI flash, USB flash drive, or SD card. When user wants to program the target chip, pressing the programming button on Nu-Link2-Pro to complete the programming action. If it needs a large number of ICs to be programming, it recommends using the Nu-Link-Gang programmer. Nu-Link-Gang programmer can perform offline programming on four different chips at a time, significantly increasing the programming efficiency. Besides, Nu-Link-Gang programmer can also use the control bus to connect with an automatic programming machine for automatic programming. In the system upgrade, Nu-Link2-Pro also provides five standard communication interfaces such as SPI, I2C, UART, RS485, and CAN for transmission, which is convenient for users to upgrade the system.
