This will land in 1.4.0 not 1.3.x as there may be minor incompatibilities (if major we should consider 2.x) At this point we should undo #819
AFAICT the only way to get at the contents of the PIO FIFO debug register is to access the `fdebug` field on the PIO struct and do the appropriate bit...
I had a problem where unresponsive Devices on the I2C would get the entire Pico stuck. Drilling into a few functions i found the [Timeout Check](https://github.com/raspberrypi/pico-sdk/blob/426e46126b5a1efaea4544cdb71ab81b61983034/src/rp2_common/hardware_i2c/i2c.c#L170) called in `i2c_write_blocking_internal`: ```...
Fixes #810 by adding stdio_uart_deinit. I would have liked to undo the pin init from `stdio_uart_init_full()` as well but we dont keep track of the pins. Could probably go through...
When driving a motor a dual slope pwm is very important. And it is supported by other cortex-m0 controllers. Is it just missing from the SDK, can a pwm slice...
frequency_count_khz() returns a frequency measurement of a given clock, by sdk-default, with an accuracy of 2 kHz. The interval value of 10 means 2 kHz, as per data sheet. Unfortunately,...
See #548. Details are quite messy. Our API supposedly lets you poke the UART settings whilst it's enabled, and doesn't impose restrictions on what state it can be in when...
This PR modifies the behavior of `pico_printf` to automatically trim trailing zeroes when using the `%G` or `%g` format specifiers. This is the behavior that is [specified by GCC](https://www.gnu.org/software/libc/manual/html_node/Floating_002dPoint-Conversions.html): >...
The PR includes 2 changes 1. better const correctness 2. the mentioned feature, every second the ISR is triggered to update the clock output
When the host running the SDK is not little endian, all data that is exchanged with the Pico must be converted to/from little endian byte order. Instead of sprinking explicit...
