Can the phase of the PIO clock of the RP2040 be adjusted?

2

Can the PIO of the RP2040 set a fixed additional phase offset for the clock of each state machine? In this way, multiple PIOs can be used to sample the...

Enable partial code encryption for larger binaries

1

The [encrypted bootloader example] demonstrates how to encrypt your binaries and have them securely decrypted in place from SRAM on RP2350. However, as it is, it only works for the...

I have two version of picotool available in my ~/pico directory: picotool-2.1.0 and picotool-2.1.1. Setting environment variable PICOTOOL_FETCH_FROM_GIT_PATH according to documentation should set which picotool to use but this always...

Enable UART on QSPI pins

9

Hi, I'm doing tests with the UART bootloader, which is described in the [datasheet](https://datasheets.raspberrypi.com/rp2350/rp2350-datasheet.pdf) of RP2350 (Chapter 5.8). The pins SD2 and SD3 of QSPI are used as TX and...

Hi, I did a code that need pio_gpio_base set to 16. However, we must use the GPIO pin number -16 in the wait instruction. if we do this, the pio...
