Data；
Alternatively, the LED dot matrix lamp source layout structure that logic control element self-identifying is connected, generates arrangement data.
As shown in figure 4, a kind of automobile tail light display methods, comprising the following steps:
Step 1, logic control element initialization, control LED dot matrix lamp source, wireless transceiver initialization；
Step 2, within the scope of time threshold, execute automobile tail light conventional func, including it is left dodge, it is right dodge, it is double dodge etc..Exceed
Time threshold goes to step 3 into predefined display pattern or distal end editor's display pattern.
Step 3 can enter predefined display pattern or distal end editor's display pattern at this time；If into predefined display mould
Formula then first judges whether triggering display specific content, if it is, extracting display data from several trigger areas of memory；If
It is no, then data are shown from memory normality extracted region.No matter which kind of above-mentioned situation, which can all update driving LED dot matrix lamp source, shows
Content and effect.Logical controllable unit directly controls LED dot matrix lamp source and shows last time automobile tail light content.
At this point, intervening if any external device, that is, enter distal end editor's display pattern.Wirelessly connecting input module carries out transmission number
According to and storage, from memory dynamic editing area extract display data.
After being wirelessly successfully connected input module, the multi-colored led dot matrix arrangement information of current automobile tail light is passed for step 4
It is defeated by mobile terminal；
It is shown if step 5, wireless transceiver receive instruction to open car light, goes to step 7；It is if receiving instruction
It shows content update, goes to step 6；If receiving instruction is that closing vehicle lamp is shown, 8 are gone to step；
In the displays content data write-in memory that step 6, logic control element receive wireless transceiver；
Step 7, logic control element read memory, drive LED dot matrix lamp source after converting according to the data content read,
Show corresponding content；The display mode that driving content is determined according to the arrangement situation of current LED dot matrix lamp source, goes to step 3；
Step 8, logic control element close driving LED dot matrix lamp source, go to step 5；
To sum up, realize that automobile tail light is shown.
Wherein, the method for point-to-point synchronization map is realized:
Method 1: the LED dot matrix lamp source arrangement data on preset configuration automobile tail light in memory；
Method 2: self-identifying is connected LED dot matrix lamp source,
LED dot matrix lamp source is connected to logic control element in a manner of matrix circuit, according to different taillight shapes, lamp bead row
Cloth is on the partial intersection point of matrix circuit；There is controllable weak pull-down resistance inside logic control element；Detect external lamp bead position
When setting arrangement, open logic control element inside pull down resistor, control one end export high level signal, when LED light exist,
The other end can detect high level；When LED light is not present, low level can be detected in the other end；Or the configuration other end is MCU
The sense channel of internal ADC obtains the voltage magnitude of the current other end, when LED light presence, detects the voltage magnitude of the other end
It is not 0, when LED light is not present, detects that other end voltage magnitude is 0.
Embodiment 1:
When driver is the new hand of rigid learning soon, the printed words of " Getting Started " can be shown in automobile tail light editor.
Mode 1: mobile phone is as input module, when driver is near oneself automobile, open Bluetooth of mobile phone, search near
