    Hi everyone,
    I am new on the forum and on the simulators.
    I have the same problem as Mr Tetesim, when I power up the avr controller with H-bridge, the four leds remain off in the middle position (512)…. LCD displays correctly the pot values...moving the pot to the end positon the corresponding LED light up. When I connect the motors, in this case 4 LEDs light up in the middle but moving the pots doesn’t light up corresponding side, LEDs are off and the motors take no action. I check the cable between AMC1.5 and DSMhb1.2 boards, the pinout orientation on the connectors are ok. I tried 5 different brand of 74HC08, 2 brands act same way, and the other 3 brand doesn’t worked, could it possible that only Philips is the right part?
    I am trying to TEST the Hardware as Mr Egoexpress specified ( how-to-test-the-avr-controller-with-x-sim-t1366.html ) but facing with this problem, I have no idea on what doing…
    Please can anyone help me.
    Thanks 260720114172.jpg
