hi

okey... my device activates when i connect the STRB bin to the ground. that activates the device. Now i want to control it from the uC pin. what i did was that i i connect the uC pin to the resistor and resistor to ground. and in between resistor and uC pin i connect the device STRB pin. so what i was expecting that when i have +5V on uC pin that should held high the device STRB but when there is 0V on the uC pin device should connect to ground through pull down resistor... that does not seems to be working... so why it is not working and how can i make a interface that i can control the device to connect to ground when there +5 or 0V on uC pin... that does not metter that i use 1 or 0 on uC to activate the device. only i want device to be connected to ground when i want.

Thanks a lot.
