TMS374 ECU Decoder

Product Description

This Tool is a frequency sweeper with 5V square wave output (Duty cycle *0%, effective frequency range from over *0kHz (max *0kHz) to *0Hz) .This tool can be also considered as a MCU version of the software TMS***4 Decoder ECU. The only difference between the two tools is that the MCU version works without a PC.

A small MCU is used to generate the pulses instead of the PC RS**2 Tx line. The TMS **4 software is in fact a simple frequency sweeper with an effective range from about ***0Hz to about **0Hz. The Tiny sweeper does exactly the same but much more better (bigger range).

After powering the device on - the LED should blink twice. Pressing the will start the sweep procedure. LED ON - means there are pulses on the output. After reaching the lowest frequency the LED goes off and the mcu stops the generation.
