Tuscan Custom LCD Screen and New Circuit board
Discussion
I imported a tuscan to the USA last year. One of my annoyances was the LCD display barely worked. Even if working, not great in the sun.
I decided to develop a complete replacement. When through a few iterations and logged the car. Developed a simulator to run the dash on the bench to collect all the information I need. I'm not finished with it, but I have all of the mechanical, screen, and PCBs worked out so far.
I'm going to start working on the the firmware, so I'm open to some suggestions for improvements. The microcontroller has full access to any of the input data. So pretty much anything can be displayed in bright graphics.
It includes a new screen, display PCB board, Main PCB. I eliminates 3 of the PCBs within the gauge cluster, but retains the use of the outer one. It mates directly and just plugs in to the front LED boards and the outer interface PCB.
New Features:
1. Speedo Calibration. They'll be a calibration section which you can just hit drive to 40mph via your GPS on your phone, hit a button on the car and it'll calibrate your speedometer perfectly. Will work with any wheel size.
2. Much louder use of the speaker range. I'm not sure if it was just mine or everyones, but the speaker was woefully underutilized.
3. Option for up to 7 tach LEDs, will work with the OEM setup or you can add 7 leds and have a full racing style tach.
4. Smooth stepping option. The TVR quark is the gauges click, the gauge will be able to retain the OEM or go to a smooth control like most vehicles. My personal preference is the leave the Speedo click, but coolant and fuel to be smooth stepping. The OEM hysteresis is annoying with it flipping back and forth between two steps.
5. It will be a full color high brightness screen, 320x240 pixels. Dual brightness setting so high brightness during the day and lower when the lights are on so you're not blinded.
6. I'll have some base firmware that matches OEM then my design with the modern display, but will make the firmware open source if I end up selling them in which people could customize their own display and screens. This isn't a money making venture, but I've designed and built it as if I will sell it eventually.
Anyways, feel free to add any ideas or such that I'm missing.
Here's the simulator which i can control all the values. This is the main circuit board, I just finished it after a ton of development time. Ill have more updates over the next few weeks/months.
