Outline of thread for spi1
Added IWDG watchdog routines to common directory.
Added second interrupt on PD9 for DIO1 from ADIS. This is the
data ready SPI interrupt. (adis development).
Updates to adis device interface
changes to adis_cb
more experiments with SPI interface.
Basic asynchronous SPI interface running.
Notes on gdb patch for hw debug on command line for stm32f4.
change kernel tick frequency
Working on reducing read times. Down to less than 150uS.
t_stall time corrected.
Clean up event broadcasting
continued refactoring of ADIS device
burst reads
doxygen template
New Chibios Pulled (submodule)
timing experiments
Doxyfile for devices directory
ADIS still functional. On tabletop, z should read -1g.
This is close enough.
