Use GPIO to bitbang the serial protocol for a DHT temperature/humidity sensor. Register an interrupt handler to run when a GPIO is toggled. Use the GPIOs to drive a seven segment LED display. Stream data using the XIP stream hardware, which allows data to be DMA'd in the background whilst executing code from flash.ĭMA directly from the flash interface (continuous SCK clocking) for maximum bulk read performance. A useful utility to drag and drop onto your Pico if the need arises.Įrase a flash sector, program one flash page, and read back the data. An example of a NO_FLASH binary (UF2 loaded directly into SRAM and runs in-place there). Show how they are affected by different types of flash reads. Read and clear the cache performance counters. Use an IRQ handler to reconfigure a DMA channel, in order to continuously drive data through a PIO state machine. Use the general purpose clock outputs (GPOUT) to drive divisions of internal clocks onto GPIO outputs.Įnable the clock resuscitate feature, "accidentally" stop the system clock, and show how we recover.īuilds two version of the same app with different configurationsīuild a control block list, to program a longer sequence of DMA transfers to the UART. Read analog values from a microphone and plot the measured sound amplitude.Ĭhange the system clock frequency to 48 MHz while running. Includes example of free-running capture mode.
