Re: Base GPIO code to work from?

Lance,

since the page you linked is referring to the MS2, is it consistent with the MS3 too? If not, what are the differences?

Where do I find the respective table numbers and offsets?

Re: Base GPIO code to work from?

Hello everyone, it's me again. I have now installed the GPIO with my MS3 and another CAN controller in my car and I managed to get a connection on first try (positively surprised there ;) ). MS3 is CAN ID 0, GPIO is ID 1 and the other controller is ID 2. Problem is: When connecting to the GPIO by CA...

Re: VRx Interrupt calls

Lance,
thank you, that was extremely helpful - especially the first paper with general info as it contains the table mapping (page 16) that I couldn't find in the manual or the code itself.
That table was exactly what I was looking for :)

VRx Interrupt calls

Hello again, I'm struggling to get the VR Sensor inputs to work. I've managed to successfully read VR1 on PT0 by modifying the template's "VSS_timer" Interrupt Service Routine. When trying to read the other sensors though, it seems that another ISR is being called that jams my controller in an infin...

Re: GPIO CPU Pinout

Lance, I'm quite familiar with the design and adaptation of electric circuits, thank you. (I'm studying electrical engineering at the moment) I just have been a little confused because the docs were somewhat unclear about what part is "general" and what part belongs to the MShift project. On the bri...

Re: GPIO CPU Pinout

Aha, so the assembly guide is designed specifically for the MShift system setup?
Maybe then you should make that a little more obvious in the guide itself.

Re: GPIO CPU Pinout

Thank you, that helped a lot.

But that gives me another question regarding that pin header: in the assembly guide (http://www.msgpio.com/manuals/assemble.htm) it is required to jumper PT7 to VB1 and AD1 to GPI2. What is the purpose of these jumpers?

GPIO CPU Pinout

Hi everyone, I'm trying to adapt the template GPIO code to suit my needs (1x EGT, 4X VR vehicle speed and possibly other stuff later). Working through the code I have met a problem I find myself unable to resolve on my own: I can't find a map explaining the connections between the PCB's circuits and...

Re: Base GPIO code to work from?

Lance,

you're the best! Thank you!
With this firmware and INI, everything works as it should and I can connect to the GPIO by serial cable as well as by CAN pass through.

Now I can move on to the "real" challenge in my project: getting the EGT1 and VR 1 through 4 to work and display ;)

Re: Base GPIO code to work from?

Well well, we're making progress. I've managed to access the GPIO by serial connection while having it connected to my MS3 by CAN. I can play a little with my stim's inputs and it gets recognized by the GPIO (for example the RPM inputs). However, I'm still unable to access it by CAN pass through. I'...
