 There are some major diffences how PowerShot and EOS have to be programmed and that is why there are 2 different project teams.\\
-It may confuse some people that there are a few EOS M cameras not handled by ML but CHDK. And there are 4 PowerShot cameras not located in CHDK realm but ML. Those cameras run code contrary to their names!\\

 EOS M3, M5, M6, M10, M100 work with PowerShot firmware and are therefore handled by CHDK.\\
-PowerShot SX70, SX740, G5 X Mark II, G7 X Mark III work with EOS firmware and can be ported to ML.

 ==== Dual-ISO ====
-Dual-ISO uses an alternating [[#line scanning]] technique to increase [[#dynamic range]]. Each alternating dual line is scanned at different [[#ISO|ISO]]s and later combined to produce an image (or video) with an increase in dynamic range similar to taking two images at the different ISO's.

 As a single imaging technique there are no motion artifacts, however a loss of resolution in the highlights and shadows, and [[#aliasing]] are the drawbacks.

+A function in the Canon firmware that can be called by string value. They can be executed with [[#canon_basic_scripting|Canon Basic scripts]], through [[#usb|PTP]], or through the //call// function in C. Internally, these are known as //evprocs//.

 **5D Mark III**: Firmware version **1.3.x up to 1.3.5** can be downgraded by using EOS Utility. It is not possible to use firmware update menu in cam without tweaking. See [[ML>forum/index.php?topic=18941.0|How to do a Canon firmware downgrade]].\\
 Firmware version **1.3.6** can only be downgraded by a tricky procedure found by user Apollo7 and fine-tuned by a1ex: -> [[https://builds.magiclantern.fm/5D3-123.html#install|Install procedure for 5D3 1.2.3]] -> Method B\\

 Physically accessing UART in older cams required opening cam and maybe even soldering wires to camera's cirtuit board. Later cams have a UART connector on board for easier access. \\
 On some of Canon's Digic 7, 8 and X cameras this UART is accessible without opening the camera by just removing a reusable rubber cover.
+==== USB ====
+Generally used for debugging. Information is transmitted over the Picture Transfer Protocol. Canon
+has added several commands alongside the standard ones, such as the one that can be used to write the [[#bootflag]] (See https://github.com/petabyt/mlinstall)
