| 2021-02-17 | raspberrypi: implement os.urandom | Jeff Epler | |
| Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit", I use the SHA256 hash function to create a high quality random seed from random values of uncertain entropy, as well as to generate a sequence of random values from that seed using SHA256 as a cryptographically-secure random number generator. In practice, it produces over 100kB/s of random data which does not have any gross problems according to _PractRand_. | |||
| 2021-01-20 | Add initial RP2040 support | Scott Shawcroft | |
| The RP2040 is new microcontroller from Raspberry Pi that features two Cortex M0s and eight PIO state machines that are good for crunching lots of data. It has 264k RAM and a built in UF2 bootloader too. Datasheet: https://pico.raspberrypi.org/files/rp2040_datasheet.pdf | |||
