ISP In Socket Programmable SPI Serial Peripheral Interface. Not quite! ISP = In-System Programmable. ie, the device can be programmed in the target System, without having to be removed from the board and put into a special programming socket. ISP and SPI are two entirely distinct and separate things: ISP is a property of a device - either it can be programmed in-system, or it can't. SPI is an interface - some In-System Programmable devices can be programmed via their SPI port. Not all devices that have SPI ports can use the SPI port for In-System Programming. Other interfaces that may be used for In-System Programming include the standard serial port (UART), JTAG, and USB. Important note from Donald Catto about Atmel's ISP via SPI: http://www.8052.com/forum/read.phtml?id=77014 A further step from In-System Programming is In-Application Programming, IAP: http://www.8052.com/forum/read.phtml?id=84586 |
