Peripheral Simulation

For STMicroelectronics STM32F103ZG — I2C Interface

Simulation support for this peripheral or feature is comprised of:

• Dialog boxes which display and allow you to change peripheral configuration.
• VTREGs (Virtual Target Registers) which support I/O with the peripheral.

These simulation capabilities are described below.

ADC2 Input VTREG
Data Type: float

The ADC2_INx VTREGs set the analog input voltages for simulated A/D converters. The ADC2_INx VTREGs represent the inputs to the analog input pins of the MCU for analog input 0, 1, 2, and so on. ADC2_IN0 sets the input voltage for analog input #0, ADC2_IN1 sets the input voltage for analog input #1, etc. If you have properly configured the analog inputs, the following commands (typed in the debugger's Command Window) input the voltages specified.

ADC2_IN0 = 0.000  /* Analog Input 0 = 0.000 volts */
ADC2_IN1 = 2.500  /* Analog Input 1 = 2.500 volts */
ADC2_IN2 = 4.999  /* Analog Input 2 = 4.999 volts */

You may create a debugger signal function to periodically change the value of the A/D input. The following signal function increases the A/D Channel 1 input voltage by 0.1 volts each second.

signal void ADC2_IN1_sig (void) {
float f;

for (f = 0.0; f < 5.0; f += 0.1)
  {
  swatch (1.0);                  // Delay 1 second
  ADC2_IN1 = f;                  // Set ADC2_IN1 Voltage
  }
}
