Hi,
I wanted to know if the TTL to USB cable like the one in the link shown below can be replaced by a MAX3232 level converter circuit and a RS232 to USB converter.

USB FTDI TTL-232 cable [TTL-232R 3.3V] ID: 70 - $20.00 : Adafruit Industries, Unique & fun DIY electronics and kits

The MAX3232 converts the TTL to RS232 logic...I connect the 3 pins, the Txd, Rxd,Gnd on the RS232 side of the converter (RS232 to USB)
The other end of the converter, i.e USB end is connected to the PC.

Please let me know if this will produce exactly the same output as the FTDI TTL to 232 cable.

I am not getting the proper output in my project so wanted to check if it was because of this.

Basically i want to transmit data from the MCU to Laptop.

Thanks very much...
