wip: Serial audio interface (SAI)

1

This PR contains some preliminary code for the SAI. In the stm32f7xx-hal a driver already exists iirc, but that driver is limited to duplex I2S. This API is slightly more...

Deadlock in Delay

1

Board: 'Adafruit Feather STM32F405' I am currently stuck debugging why my program loop gets stuck while during executing a delay. ```rust loop { feather.led.set_low(); let c = block!(feather.usb.read()).unwrap(); feather.usb.write(c).unwrap(); feather.led.set_high();...

Quadrature Encoder Interface could use internal pull-ups

1

The QEI example uses external pull-ups https://github.com/stm32-rs/stm32f4xx-hal/blob/b9bff7be5605fa97d9d293e8e0f52594a744b1f9/examples/qei.rs#L10 but the stm32f4 has built-in pull up resistors that can be enabled. The `Qei::new` function takes `Pin`'s which don't have their pull up/down/floating...

The ADC field `calibrated_vdda` and the functions `sample_to_millivolts`,`make_sample_to_millivolts` and `reference_voltage` + their configuration counterparts use millivolts as unit of measurement. While the VREF+ of the STM32F4xx CPUs is in the...

Quadrature Encoder Interface only supports rising edge polarity

2

In the timer encoder mode, we have a hard-coded configuration of the polarity the encoder input: https://github.com/stm32-rs/stm32f4xx-hal/blob/d96137099d47112bf891d72df1c066409afacb4e/src/qei.rs#L79 and on the following lines cc1p and cc2p are cleared, setting the polarity...
