46. Slide 46: Universal Editors and Universal Hex

    Universal Editors and Universal Hex Maximising continuity • Users will not have to select their board version to use any existing micro:bit features. • Users will see blocks for V2 boards listed in a special category in the block explorer • If you only only use features that are common to V1 and V2,

47. Slide 47: One hex file will work on all boards

    One hex file will work on all boards …except when it uses v2 only blocks V2 V1.5 If a hex file uses the Hex (nrf51) V1.5 common subset of features V2 hex only, it will work on all (nrf52) boards Combined hex using common subset V1.3 © Micro:bit Educational Foundation 2020 47

48. Slide 48: One hex file works on all boards

    One hex file works on all boards …except when it uses v2 only blocks V2 • If a hex file uses features that are v2 only, it will not work on a v1 board V1.5 • The error will occur as soon Hex (nrf51) V1.5 as a feature is used V2 hex • This means ‘at startup’ for ‘On (nrf52) sound’ events Combined hex

49. Slide 49: Microphone indicator

    Microphone indicator • When the microphone is recording there will be an indicator on the front of the board that it is ‘listening’. • When the microphone is not recording, the indicator is not really visible/doesn’t detract from the look of the device • We want to make a feature of the privacy ques

69. Slide 69: The idea comes first!

    The idea comes first! • This approach is one of the key things that sets micro:bit apart ….And one of our key tools in making micro:bit relevant and engaging for children that might not currently think computer science/engineering is for them • We want children to feel confidence and ownership over
