The setup for the various ICS control register is also described wthin Chapter 10. A word-clock generator will centralize all of the timing of various pieces. Further information about these issues may be obtained from the device datasheet, Chapter 10: Internal clock source, and also Appendix A.8. Cut the LEDs into lots of 11 - Ensure you cut in the middle of the marker as shown. The LEDs currently function as a strip but we need to make them more square. ![]() On the basis that you have considered these protection issues, you will need to decide the frequency range to be used - low range 32-38.4kHz, or high range 1-5MHz. You will also need to decide the operating mode for the ICS module, FEE, FBE or FBELP. Step 2: Build Word Clock LED Matrix (Back) The core of the clock is an LED matrix. If you do not wish to use the internal reference, or an external crystal reference, a much safer alternative would be to use a packaged oscillator that provides a CMOS compatible output, permanently connected to the EXTAL pin. Yet another issue may be the possibility of front panel frequency adjustment, accidental or otherwise, causing the maximum allowable bus frequency to be exceeded. This becomes even more important if the function generator has a variable outpur level, or is capable of negative output swings using front panel controls. To prevent damage to the MCU, this may require additional buffering and protection circuitry. You will also need to consider the possibility of static discharge into the pin, and its suppression. The Apogee Wordclock Card in connector is hard wire terminated and you cannot make it unterminated without performing a little internal surgery (see. so at least two different master clock generation systems are required. The main issue will be to provide sufficient protection of the EXTAL input pin from excessive voltage swings from the generator. To make 48,000 digital samples for ADC on an analog signal, the sampling clock. You do not mention your reason for wishing to use the function generator? THE CLOCK GENERATORS The clock generator is made up of two sections: 1) A low-range generator capable of clock frequencies from 7Hz to 3MHz 2) An RF clock generator covering a range of 8kHz up to 125MHz The low-range generator is handled using the ESP32’s clock generator dedicated to its I 2 S function block.
