The systematic structure uses load cells as sensors, and a low complexity microprocessor, DPF-MCU, to transfer and display the related counterforce data. Previous works show that the counterforce is obtained either by measuring the power consumed by motors or by using the force plate placed under the running belt. These two ways of measurement is quiet mature and being used for years. But is limited to medical and commercial usages only. The costs of these previous works are much higher than home-use treadmill on average which makes them difficult to be widely accepted by consumers. In this thesis, we adopt the load cell principal to measure the counterforce, and then display the counterforce measurement on the treadmill console. All the related data transfer operations and peripheral controlling are realized by using a low complexity microprocessor. Therefore, the cost is effectively reduced. In addition, the majority of home use treadmills on the market are mono LED or LED interface operating. For our example, we use the DPF-MCU and a 7” TFT LCD Module to make the dashboard more colorful, more high quality looking, and to attract consumers.
