Before all the exciting stuffs like getting selected to do Roadtest, receiving packages and unboxing them, there was an idea which ignited all of these exciting things, and that's the topic/idea I am going talk here...
My proposed idea was SMART HEADLIGHT for vehicles, especially cars... The Smart Headlight is aware of surrounding light sources and make the headlight illuminate accordingly. The bright LED lights for highway and dark environment, the yellow LED lights for gradual light source and the blue LED light for city drive with enough ambient light sources.
I am going to use through hole LEDs as light/ambient sensors and send the data to MSP-EXP430FR4133(MSP430FR4133) using 10 bit resolution ADC channel, for now single channel is enough to do this job, I think. According to the light source the LEDs reacts as sensor and sends data in mV to ADC channel, I am going to use LEDs in parallel to get enough voltage for ADC sampling. The brighter the light source higher the voltage is, so the lowest voltage trigger the White LEDs and the highest will trigger the blue LEDs. The neutral sensor data will trigger yellow LEDs.
For the development environment my option is Code Composer Studio from Texas Instrument, IAR workbench and the third party Energia (Arduino look alike), I am going with CCS with 16KB limit licence as the MSP430FR4133 has 16KB and I am learning the environment now, succeed with blinking the onboard LEDs...well I am really getting my hand wet with embedded programming.
I am also going to use TPS92512EVM-001TPS92512EVM-001 Led Driver for the headlight as it needs high current driver...I have no use of CC2540TDK-LIGHTCC2540TDK-LIGHT for this project but I told in my idea that I am going to use it to control headlight via BLE...Maybe my idea is to snap off the 4 onboard LEDs and use the trace contacts with use of BJT NPN transistors to control 4 set of LED range...hmmm...I will do this after the main project idea.
I am going to create the headlight LEDs from scratch, I have requested high power bright LED in white, yellow and blue from Würth Elektronik they have already sent me first set of passive components(Thank you guys)...I am going to create PCB for the LEDs and etch with ferric chloride. I will post all the PCB greber files and video of etching process.
For now it's learning time for me I will post more in detail review of MSP-EXP430FR4133MSP-EXP430FR4133 TPS92512EVM-001TPS92512EVM-001 and CC2540TDK-LIGHTCC2540TDK-LIGHT along with my project updates
