|\ | | | | | | embassy_rp: improve calculate_pio_clock_divider
| * clock_divider: use core::assert in const fnEric Seppanen2025-12-131-3/+3
| | | | | | | | defmt::assert gives a compile error in const context.
| * improve pio clock divider mathEric Seppanen2025-12-131-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that the fractional part of the clock divider is accurately calculated. This does additional u32 division/mod operations, which I think is better than using u64 for its extra precision. Also: - Add additional asserts to catch out-of-bounds results. - Make the version that accepts the system clock as a parameter const and public, so if anyone wants to hardcode the system frequency they can avoid any runtime computation. - Remove the `inline` attributes because the function has grown quite a bit.
| * add unit test for calculate_pio_clock_dividerEric Seppanen2025-12-131-1/+29
| | | | | | | | | | The test will fail, because the current implementation doesn't calculate the fractional part.

| * rp/pio: Add onewire strong pullups, parasite powerMatt Johnston2025-09-141-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | DS18B20 sensors require a strong pullup to be applied for the duration of the temperature conversion, within 10us of the command. The rp2xxx pins have sufficient drive strength to use as the pullup (no external mosfet needed). Add a new write_bytes_pullup() that will apply the pullup after bytes are written. Existing read_bytes()/write_bytes() has no change to onewire timing. A pio_onewire_parasite example reads multiple sensors individually, applying the strong pullup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a new PIO program which implements SPI. This allows you to drive more than 2 SPI buses by using PIO state machines as additional duplex SPI interfaces. The driver supports both blocking and async modes of operation and exclusively uses the DMA for async IO.

| | | | | | | | | | | | | | | | | | | | | Updated the MPU region enablement logic in the `install_stack_guard` function to correctly set the region limit by using the stack bottom address plus 256 minus one, ensuring proper memory protection configuration.
