Would it be possible to implement serial eeprom read/write over i2c? This would be very useful for reverse engineering. I have constructed a 3.3v to 5v bridge using an ISO1541 ic and can access data on a xicor x24c04 serial eeprom but reading/writing the individual bytes one at a time is somewhat useless. If you could add the option to dump and write i2c eeproms to and from a file it would expand the usefulness of the tool a great deal. If you need hardware to test it on i can offer mine. Thanks for everything you have done so far.
Hello,
Do you think you can add a feature that lets one read the addresses of 1 to 2 i2c modules and then change their addresses where possible?
Many other flipper apps show their wiring configuration within the app, either on a menu or some other graphic. It would assist new users of this application for your wiring layout (as shown in your readme) to be a part of the apps main menu, or for there to be a "wiring" option on that menu that shows the required wiring setup. Thanks!
Hi,
I'm trying to compile this app as a user application on the official firmware.
It builds fine, but when the fap is uploaded to the flipper, I get an API Version Mismatch error.
Do you know why this is?
Here's my build log:

Is it possible to either add an additional menu option to write an 8 bit value to a register at a specified device address?
I’ve been playing with the MCP23008 & MCP23017 GPIO Expander chips lately. Today I had the idea to hook my flipper up to the PCB I’m using. I was able to scan and find the address of the chip (0x20, right where I expected it to be) and send (maybe read is a better way to put it) to some of the chips registers. This brought up a reason for this post.
In order to really use the GPIO Expander, you need to be able to write to the registers a value. The Flipper’s current implementation of the I2C tools only provides a way to read a register from an address. What would it take to make it able to allow for the user to select the device address and write a byte to a register.
For example, I might want to send:
Device Address: 0x20
Device Register: 0x00
Option: (0 = Read, 1 = Write)
Register Config: 0xFE
(Provided the previous option is set)
and when the transaction is completed, receive an ACK or NACK.
Having this ability would really be sweet and educational for those exploring the I2C protocol.
I'm trying to build this code, but multiple files reference this header, and and I don't see the header anywhere in the repo. Is this a mistake, or am I supposed to generate this file somehow?
Hello! thanks for all your work on this repo, its helped me alot with my own flipper zero apps. I was wondering how you were able to record the screen on the flipper and convert it to a GIF to be used in the readme?
