Honestly I do not know what sort of I2C communication problem I ran into at that time. I would not worry about it though, the teensy handles I2C fine. Maybe I was just polling the external Adc too fast. I just did not have the time to debug. So I solved the problem digitally by switching to...

Long time follower of your project. Nice to see you moving up to Teensy 3.6. I studied your code in the past. Very nice job. I completed a Teensy 3.6 project (hydraulic 4 wheel steering) which receives Canbus data from a Megasquirt. I actually used TunerStudio to display real time steering...

I have used this board with sucess. I still need to put a resistor across VR Sensor wires occasionally to get 100 % reads. http://jbperf.com/dual_VR/v2_1.html Mark

Your welcome. I changed my code around a little as I needed to restrict my data to two byte integers. I am now using: uint16_t CLT, RPM, MAP, MAT, BATTV, TPS, GSI1, GSI2; switch (rxmsg.id) case 1512: MAP=((int16_t((rxmsg.buf[1]) | (rxmsg.buf[0] << 8)))/10)...

Glad your headed in the right direction now. I started the engine A OK. It was a problem with throttle linkage that was connected to an automatic governor. Now I will see if I can get some more data from the MicroSquirt.

I was typing fast on my reply last night as my laptop battery was dying. I will be attempting other ID's today. Also I need to check TDC and reset the timing I think the firmware update threw off my initial offset. I am not sure as I haven't tried starting this motor in 6 months. I should...

OK today I upgraded the firmware of my MicroSquirt to 3.4.1 and turned on Dash Broadcasting. I added some code to an existing program that I am using on a Teensy3.1 and read coolant temperature from the 1512 ID. It updated as I applied heat to the sending unit and cooled down when I removed...

Give a me a couple days, I will give it a try. I have a microsquirt on a running engine. I currently have two teensy3.1s talking over can bus to each other. I will connect the microsquirt to the mix and see if I can receive the 1512 packet with live data. Mark

Let me ask you a few questions first. What Microsquirt Firmware Version are you running ? I assume you have broadcasting enabled in TunerStudio. What is the interval set to ?? What data do you have it sending?? Do you have an running engine or a JimStim? Mark

I see FastCRC uses the on-chip hardware for Teensy 3.0 / 3.1

I wanted to post to thank everyone who worked on getting the canbus drivers for the teensy3.1 completed. I am working on a project which uses two teensy3.1's working together to implement 4 wheel steering on an industrial platform and was able to use the canbus drivers for tennsy3.1 to...
