Problem in LN298 and microcontroller
2011-05-17 01:18 AM
hi,
i am trying to drive a dc motor (20v) using LN298 and ATMEL microcontroller, when i try to drive the dc motor with LN298 alone (without microcontroller) it works good. and when i try the microcontroller alone it gives the right output (testing on leds) but the problem apears when i try to connect the microcontroller directly to the LN298. the LN298 takes its first state from the microcontroller and then the microcontroller stops (i doesnt respond to anything after that) i tried to put ULN2003 between the microcontroller and LN298, i also tried to put an inverter between them, i also tried transistors and diodes but the same problem appears each time the microcontroller stops responding after it gives the first output to LN298 can any one help please...2011-05-17 01:18 AM
check your power supply
it seem that u don't have egnouh power are using Batterys ?? the Vs = 20V MOTOR VOLTAGE the VSS = 5V TTL/CMOS[ This message was edited by: Cortex on 05-04-2005 00:30 ]
