1133: rp: Fill and empty FIFOs in buffered uart interrupt r=Dirbaio a=timokroeger
Fixes an issue where only the first byte was transmitted. Should improve throughput aswell.

1128: Add missing SPI pins r=Dirbaio a=pferreir
The SPI definitions lack the pins which are not accessible on the pico (but are so e.g. on the stamp).

1124: Fix two SPI bugs for stm32 r=Dirbaio a=rmja
This PR fixes two bugs:
* It fixes#1095 by ensuring that pin speed is VeryHigh for all spi versions. I am on stm32f429 which seems to be spi_v1, and it also needs the VeryHigh pin speed. Otherwise bit errors on the "last bit in every byte" can happen.
* It also fixes a lifetime bug for the tx buffer when sending "write_repeated". The issue can be seen when doing spi.write where the clock byte changes during a transmission because the buffer handled to the dma must live throughout the entire transfer.

1121: Add examples for stm32f0 r=lulf a=imrank03
Hello `@lulf,`
I added some more examples to stm32f0 and tested on hardware.
With love,
Imran

1119: add convert_to_celsius function in the adc module r=lulf a=overheat
modify RP2040 adc example to get inside biased bipolar diode voltage,
then convert this temperature sensor data into Celsius degree,
according to chapter 4.9.5. Temperature Sensor in RP2040 datasheet.

1114: nrf/uart: do not error on zero length transfers. r=Dirbaio a=Dirbaio
It's a perfectly fine thing to do, should be just a noop. Erroring is really annoying when you're writing a payload to uart that might be zero-length or not.
