# Canon lens management.
Management of some Canon Lens.
Management of some Canon Lens. Checked: EF85, EF200 and EF400.
[Documentation about first "crack" methods](https://github.com/eddyem/canon-lens).
## Pinout
* PA4 - lens detect (zero active);
* PA5,6,7 - SPI SCK, MISO, MOSI;
* PA10 - USB DP pullup (zero active);
* PA4 - lens detect (low active);
* PA5,6,7 - SPI SCK, MISO (should have external pullup), MOSI;
* PA8 - enable lens power (high active);
* PA9 - !OC - overcurrent detected (low active);
* PA10 - USB DP pullup (low active);
* PA11,12 - USB DM, DP;
* PA13,14 - SWD IO, CLK;
* PB8,9 - CAN Rx,Tx;
* PC13 - USB/CAN (solder jumper to turn on CAN instead of USB, zero - CAN).
Protocol have a string form, each string ends with '\n'. You should wait an answer for previous command before sending next,
or have risk to miss all the rest commands in one packet.
## USB commands
Protocol have a string form, each string ends with '\n'. You should wait an answer for previous command before sending next, or have risk to miss all the rest commands in one packet.
## USB commands:
### Base commands
0 - move to smallest foc value (e.g. 2.5m)
1 - move to largest foc value (e.g. infinity)
d - open/close diaphragm by 1 step (+/-), open/close fully (o/c) (no way to know it current status)
f - get focus state or move it to given relative position
h - turn on hand focus management
i - get lens information
l - get lens model
r - get regulators' state
debugging commands:
F - change SPI flags (F f val), f== l-LSBFIRST, b-BR [18MHz/2^(b+1)], p-CPOL, h-CPHA
G - get SPI status
I - reinit SPI
R - software reset
S - send data over SPI
T - show Tms value
> **0** move to smallest foc value (e.g. 2.5m)
> **1** move to largest foc value (e.g. infinity)
> **a** move focus to given ABSOLUTE position or get current value (without number)
> **d** open/close diaphragm by 1 step (+/-), open/close fully (o/c) (no way to know it current status)
> **f** move focus to given RELATIVE position
> **h** turn on hand focus management
> **i** get lens information
> **l** get lens model
> **r** get regulators' state
### Debugging or configuration commands
> **A** set (!0) or reset (0) autoinit
> **C** set CAN speed (25-3000 kbaud)
> **D** set CAN ID (11 bit)
> **E** erase full flash storage
> **F** change SPI flags (F f val), f== l-LSBFIRST, b-BR [18MHz/2^(b+1)], p-CPOL, h-CPHA
> **G** get SPI status
> **I** reinit SPI
> **L** 'flood' message (same as `S` but every 250ms until next command)
> **P** dump current config
> **R** software reset
> **S** send data over SPI
> **T** show Tms value
> **X** save current config to flash
