Why Dev Kits Need BIST
DEV-monkey.com Senior Reviews Editor Jon Titus wonders why more dev kits don’t contain built-in self-test (BIST) capabilities loaded the Freescale software and USB drivers, but the lack of ANY instructions on how to connect and use the hardware brought his investigation to a rather abrupt halt:
“Recently I checked out an accelerometer kit from Freescale (RD3172MMA7456L, $99).
