 TMS374 ECU DECODER description
This Tool is a frequency sweeper with 5V square wave output (Duty cycle 50%,
effective frequency range from over 10kHz (max 50kHz) to 50Hz) .This tool can be
also considered as a MCU version of the software TMS-374 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 RS232 Tx line.
Manual
reaching the lowest frequency the LED goes off and the mcu stops the generation.
