Pastebin is a website where you can store text online for a set period of time. Fault events: Three different fault events are monitored: 1) Self-diagnosis of undervoltage lockout and overcurrent fault implemented by the opto gate drivers. Timing it’s definitely one of the biggets problems when emulating/reading the controller protocol. That could be used for delay loops or to measure execution time. Copy the library header to the appropriate project directories (Inc). Milliseconds based delay is done using systick timer which makes interrupts every 1ms generated by HAL library. Because register manipulation is cycle accurate we can design delay loops in PRU1 to give us a programmable sample rate, independent of PRU0 operation. We could have a timer tick at 80 MHz, but that might be too fast for many of our applications. RCC > HSE > Crystal/Ceramic Resonator. Back EDA & Design Tools. Therefore, in this tutorial, we’ll be interfacing the LCD 16×2 display in the 4-bit mode which requires 6 GPIO pins.
