11. 11 Outline The Take-Home Kit Programming Debugging wsn.eecs.berkeley.edu

12. 12 Programming What does it really mean to “program GINA”? – Programming the processor (MSP430) through JTAG interface – Write drivers to control the peripherals wsn.eecs.berkeley.edu

13. 13 Programming What is JTAG – Joint Test Action Group (JTAG): common name for standardized IEEE 1149.1 “Standard Test Access Port and Boundary-Scan Architecture” – Initially: captured data is serially shifted out and externally compared to the expected results (debugging sub-blocks on Integrated Circuits) – Later: programming non-volatile memory How the Processor interacts with the peripherals – GPIO pins, I2C, SPI, ADC, UART wsn.eecs.berkeley.edu

14. 14 Programming Using IAR… (demo) wsn.eecs.berkeley.edu
