Is anyone dealing with motor control based on arm7 micros ? there some few appnotes from nxp kit from st for motor control, analog promoting aduc's.
I am interested in reliability these micros can show under hard conditions EM temperature mechanical .
The majority of ARM are 3.3V or below. Most of the ARM vendor target the market of PDA, LCD etc. Very Few of solution suit the auto or industry environment.
Have you considered the microchip "J" parts? They are 3.3 volts also. I will never consider them because of the voltage issue. Though They are really cheap and fast.
AD is good with samples - but better to have corporate email and company details when registering for free goods.
BTW there are about 75 eval board and less than 300 sdk with jtag . May be better to pay for the last .
aduc pros :
adc 12 bits 1 MS/sec
cons
- 40 MHz clock less than on others arm chips
- only one adc (i need at least synchronous 2)
- less ram only 8 KB compared to lpc2148 , will decrease high speed code size could be placed into ram against flash slowness
i found another chip cortex arm STM32F103x8
with two 12 bits 1 usec conversion time ADC .
digikey prices not much expensive .
Who has experience on st chips ? I need quick decision to be done on the subject . Are ST chips especially ADC, interrupts, timers, fast inout operations emc not much buggy to start with ?
