Application Descriptions
Punch Gauge Accelerometer Algorithm
The Punch Gauge code runs a peak and hold algorithm in a tight loop continuously updating until
there is a change in the program state. Both the X and Y-axis accelerometer outputs are sampled
separately and continuously. The higher of the two axis measurements is reported as the score.
At Rest Peak and Hold
When the operator initiates a Punch Gauge punch, the punch code begins reading the instanta-
neous X and Y-axis accelerometer outputs for a period of three seconds. This is to measure maxi-
mum at rest acceleration that the board experiences. This is saved as a baseline for the punch
measurement.
Punch Peak and Hold
After the Punch Gauge has stored the baseline at rest acceleration, the punch code begins continu-
ously sampling both the X and Y-axis accelerometer outputs. The code continues to sample and hold
the peak values until the operator terminates the operation by pressing SEL button. During this sam-
pling period the operator "throws" a punch or punches. The algorithm continues to peak and hold
until the operator presses SEL button.
When the SEL button is pressed, the punch code subtracts the at rest X-axis baseline reading from
the punch X-axis peak reading and subtracts the at rest Y-axis baseline from the punch Y-axis peak
reading. The greater of the X and Y-axis results is reported as the punch acceleration.
Temperature Measurements
The temperature sensing demonstration shows how the PSoC is used to sense temperature using a
thermistor. The thermistor resistance varies with temperature following a predictable non-linear
curve. The temperature-resistance relationship is given by the Steinhart-Hart equation:
1 /Tk = A + B.ln(R) + C.(ln(R))3
Where:

The same equation, when converted to Celsius scale is as follows:
Tc = Tk - 273.15; where Tc is temperature in degree Celsius.
The PSoC can measure the voltage across the thermistor but not the resistance value.
