Override Hot Shoe by script.

Hi friends I have a Canon SX50 and after I lot of search I can't find information if can I override hot shoe status by script (LUA o uBasic).

There is a way to do this?

I know that CHDK has this option, but for my script needs I need to set hot shoe as "empty", run some lines of code and set hot shoe as "present".

Best Regards, Jair

That capability was added to the CHDK  Enhanced Photo Operations menu starting with CHDK 1.3.0.

The menu item is called  Hotshoe override  and the options are [ Off  Empty  In Use ]

To access this from a script,  use the set_config_value( ) fuction.  Use something like this in your Lua script :

Code: [Select]
--[[
@title Hot Shoe
@chdk_version 1.3
]]--
cfg=require("gen/cnf_core")
print("hot shoe disable")
sleep(1000)
set_config_value(cfg.hotshoe_override,1)  -- set hot shoe as empty
sleep(1000)
print("hot shoe enable")
sleep(1000)
set_config_value(cfg.hotshoe_override,2)   -- set hot shoe as present
sleep(1000)
print("done")
sleep(1000)

Note : this needs to be added to the CHDK 1.3.0 user manual
