The MFR Series Metal Film Resistors are

manufactured using a vacuum sputtering system

to deposit multiple layers of mixed metal

alloys and passivative materials onto a carefully

treated high grade ceramic substrate. After a

helical groove has been cut in the resistive layer,

tinned connecting leads of electrolytic copper

are welded to the end-caps. The resistors are

coated with layers of blue color lacquer.

For resistors operated in ambient temperatures above 70°C, power rating must be derated

in accordance with the curve below.

Under ce6, I want to make a more general driver to control the gpio port. I would like to hear your better suggestions.: ce6 does not support direct control of gpio in the application, so I want to make a simple stream interface driver and provide an interface through deviceiocontrol.

Is the boss interested in TI's IQMATH library? How about translating it into C code together?: After some comparisons, I found that the floating point unit of 28335 is 32bit, and its performance is not as far away from that of 2808 using IQMATH as I imagined. In this way, the CORTEX-M3 core of ...; 天凉好个秋 stm32/stm8
