• There are quite a few drivers that need serious help, IMO:
  • ADC
    • https://github.com/esp-rs/esp-hal/issues/326
    • https://github.com/esp-rs/esp-hal/issues/449
    • https://github.com/esp-rs/esp-hal/issues/902
    • https://github.com/esp-rs/esp-hal/issues/1203
  • DMA
    • https://github.com/esp-rs/esp-hal/issues/489
    • https://github.com/esp-rs/esp-hal/issues/954
    • https://github.com/esp-rs/esp-hal/issues/1235
    • https://github.com/esp-rs/esp-hal/issues/1245
  • GPIO
    • https://github.com/esp-rs/esp-hal/issues/561
    • https://github.com/esp-rs/esp-hal/issues/740
    • https://github.com/esp-rs/esp-hal/issues/745
  • Interrupts
    • https://github.com/esp-rs/esp-hal/issues/1063
    • https://github.com/esp-rs/esp-hal/issues/1162
• Some others probably need less help, but should still be improved as much as possible:
  • UART
    • https://github.com/esp-rs/esp-hal/issues/944
    • https://github.com/esp-rs/esp-hal/issues/989
    • https://github.com/esp-rs/esp-hal/issues/1181
    • https://github.com/esp-rs/esp-hal/issues/1216
  • I2C
    • https://github.com/esp-rs/esp-hal/issues/910
    • https://github.com/esp-rs/esp-hal/issues/1271
    • https://github.com/esp-rs/esp-hal/issues/1306
  • SPI
    • https://github.com/esp-rs/esp-hal/issues/469
    • https://github.com/esp-rs/esp-hal/issues/489
    • https://github.com/esp-rs/esp-hal/issues/954
• All of the above peripherals need to have their public APIs reviewed and improved:
  • APIs should NOT be reliant on third-party trait packages
  • APIs should be consistent (moslty with regards to conventions)
  • APIs should be simple, easy to use, hard to screw up, and well documented
• We need to start addressing other technical debt as well (boo, no fun, I know)

  • https://github.com/esp-rs/esp-hal/issues/1203 (isn't this an ADC issue? … ah yeah it is and it's listed there … probably we can remove it from this section)
