TMS320F241PGA Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 20 MHz. However, it's recommended to use a crystal oscillator or an external clock source for more accurate and stable clocking.
• How do I configure the GPIO pins as inputs or outputs?
  The GPIO pins can be configured as inputs or outputs using the GPIO Direction (DIR) register. Set the corresponding bit in the DIR register to 0 to configure the pin as an input, or set it to 1 to configure it as an output.
• What is the purpose of the JTAG pins, and how do I use them?
  The JTAG (Joint Test Action Group) pins are used for debugging and programming the device. They allow you to connect a JTAG emulator or debugger to the device, which enables you to debug and program the device using software development tools like Code Composer Studio.
• How do I use the ADC (Analog-to-Digital Converter) module?
  The ADC module can be used to convert analog signals to digital values. To use the ADC, you need to configure the ADC module using the ADC Control Register (ADCTRL), select the analog input channel using the ADC Multiplexer Register (ADCMUX), and then start the conversion using the ADC Start Conversion Register (ADCST). The converted digital value can be read from the ADC Result Register (ADCRES).
• What is the purpose of the Watchdog Timer (WDT), and how do I use it?
  The Watchdog Timer (WDT) is a timer that resets the device if it is not periodically reset by the software. This is useful for detecting and recovering from software faults or hangs. To use the WDT, you need to configure the WDT period using the WDT Control Register (WDTCR), and then periodically reset the WDT using the WDT Reset Register (WDTRESET) to prevent a reset.
