6.2.4 Read single values of camera setting
All camera internal registers of settings may also be read as single values.
Command: :Z<c><xx> request for single register value of camera setting
<c> … ‘a’, ‘c’, ‘r’, ‘m’ (ascii characters)
<xx> … extension, which can differ in dependence
of the wanted camera setting
Valid commands: :Za<n> output of value of analog register, in ascii characters
<n> … 1 - 8 (ascii character)
:Zcs output of sensor clock code
:Zcp output of pixel clock code
:Zr<xx> output of fpga registers r,
<xx> … 01 – 0f (hex, in ascii characters)
:Zm<n> output of special fpga registers m,
<n> … 0 – f (hex, in ascii characters)
Response: for :Za<n> , e.g. 6d↓ (hex, 2 ascii characters + CR)
for :Zcs , e.g. 41bb0b↓ (hex, 6 ascii characters + CR)
for :Zr<xx> , e.g. 03ff↓ (hex, 4 ascii characters + CR)
for :Zm<n> , e.g. 00000000↓ (hex, 8 ascii characters + CR)
or for incomplete or invalid command (e.g. :Zx): NAK if enabled by separate
command :A<n>
6.2.5 Reading camera temperature
To control the temperature inside , the camera disposes of an internal temperature sensor. The tempera-
ture inside the camera can be read out in steps of 0.5°. The value is delivered in ASCII characters
signed.
Command: :T
