LM3S1608-IQC50-A2 Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for the LM3S1608?
  The recommended crystal oscillator frequency for the LM3S1608 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
• How do I configure the GPIO pins on the LM3S1608?
  The GPIO pins on the LM3S1608 can be configured using the GPIO peripheral registers. The GPIO pins can be configured as inputs or outputs, and can also be configured to have pull-up or pull-down resistors.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins on the LM3S1608 is 4 mA. However, it is recommended to limit the current to 2 mA to ensure reliable operation.
• How do I use the ADC on the LM3S1608?
  The ADC on the LM3S1608 can be used by configuring the ADC peripheral registers. The ADC can be configured to operate in different modes, such as single-shot or continuous conversion mode, and can also be triggered by different sources, such as a timer or an external signal.
• What is the maximum sampling rate of the ADC on the LM3S1608?
  The maximum sampling rate of the ADC on the LM3S1608 is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system clock frequency and the ADC configuration.
