Config program. Early days. Click on the desired port and then select desired function. Upload to car via dongle. [attachment=38483] Here’s a newer pic I’ll use for now in the program.  [attachment=...

Hi Guys,     You will be able customise the MPD into thousands of possible configurations.      The two 12C data ports are particularly interesting considering the possible combinations. And there are...

Moved motor wires to centre rear. Scorpius photo sensor for Scalextric DPR removed. PCB flyleads reduced to a minimum.  Trade off is chip is bigger however it’s neater than previous versions. Also I’m...

And if I want to make it 24mm long I can do this. Just 2 flyleads now. But it has to be that way because JSTs do not come in SMD female. And 100% compatibility for both firmware and connecting wires i...

So now we have not one but two data ports how to present this in useable functional format, yet keep production costs down.  On one LED on a fly lead with heat shrink is 21 actions, half of them by r...

So on investigation the nRF52832 can handle two 12C streams simultaneously. Hmmmmm

So we added 4 pins that can handle RX/TX communications.  So we now have 12C and UART onboard. Proposed uses so far: 1. Hall sensor  2. OLED screen controller  3. Sound controller 4. Brushless motor c...

Ok this project is also a go ahead.  One issue. Memory. The MPD won’t be able to store complex graphics however it can pull off gantry lights, numbers and letters etc. Good enough for what we need.  :...

Race position on OLED screen. The only way this could work is for the chip to stop receiving  controller data, transmit a request to race software on a specific channel, wait for x mSec to receive a ...

Yeah we have the foundations down,  (big job) we slowly introduce some of the more fancier features. This is where the real fun starts.  The TX/RX port opened up a whole new list of possibilities. The...

In short I want to be able to allocate all the LED drivers, the two pairs of photo transistor pins and the TX/RX port for various functions. Example any LED driver output be configured to 1 of 8 funct...

Hi Guys,     First digital decoder in the world that can operate an OLED screen in car.  Currently displaying car ID.       [attachment=38192]

Firmware. You can tell a lot about a project by the quality of the firmware, or total lack of. It truly what separates the men from the boys. :wavegreen:

Still a few hours to go but here’s version 5 of the MPD. John has smashed this out in a few hours so far. After increasing length 1.5mm to get enough room for all the required pins plus removing the t...

Size comparison. MPD Nitrous 292.6sqmm Carrera 469sq.mm A 38% reduction in size. Plug n play. Wireless. App connect. [attachment=37872] [attachment=37873]

So we found out that we need an old school electrolytic capacitor instead on the slim surface mounted ones we tried. This means I need an additional 2 pins to connect to. This means a board re-design ...

Programming a controller. [attachment=37847]

I once seen a pcb made to be able to connect a pcb to a pcb.

Hi all,   Postman dropped this last week and I’ve sent one up to John who received it today to include in our light protocol firmware.  Screen size is just 12.5mm. It connects via 4 pin JST plug using...
