What's new

  • adds I²C-Scanner which scans the I2C-Bus (SDA: Pin 15, SCL: Pin 16) for available 7-Bit slave addresses.
  • shows the number of detected slaves and their addresses (maximum of 8 addresses fit the screen).
    i2c_scanner

Verification

  • Connect one or multiple I²C components to the I²C-GPIOs of the Flipper (SDA: Pin 15, SCL: Pin 16, shared GND)
  • If your I²C-slave doesn't provide Pull-Up resistors you have to connect one 4k7 ohms resistor from SDA to 3V3 and one from SCL to 3V3
  • Go to "GPIO"->"I2C-Scanner" and press the "ok" button to start the scan.
  • The green LED will light up for half a second and after that the display will be updated with the number of slaves detected and their I²C-Addresses.

Checklist (For Reviewer)

  • PR has description of feature/bug or link to Confluence/Jira task
  • Description contains actions to verify feature/bugfix
  • I've built this code, uploaded it to the device and verified feature/bugfix

Hi@GitChris3004

Sorry for delay, this PR is waiting for ELF support to be merged first.

@GitChris3004 we've merged ELF support. How about moving this feature to external application?

Hey, that's nice. I will have access to my flipper in about 2 weeks again. Then I can resolve the remaining merging conflicts. What do you mean with moving it to external application?
