Thanks, I'll take a look at that, might be simpler than fatfs although that has the merit that it can be built on the host from 'normal' files. I have managed to reproduce the error from a fairly minimal program. I took the arrays and then made repeated small routines to memcpy to malloc'd PSRAM. As...

Hi, don't know how 'old..er' your moto is, I've worked on electrics from 70s to 90s. Nothing CANBus at all. A few things I've run into: 1. It's not really 12V. If you've standard lead acid battery and alternator/charger it may reach nearly 14V, and on an old moto with a weak alternator and a big hea...

Thanks, I've not managed to set a minimal fail code as yet. World is set with arrays like this to set vertex coordinates, which is the largest array: const Vec3f cvertices[NVERTS + 1] = { {0.f,0.f,0.f},// Dummy vertex to allow OBJ standard indexing {40.000000f, 0.000000f, 90.000000f}, {50.000000f, 0...

Hi, first time posting after a fair bit of reading as a guest. I've done a fairly thorough search of ideas here and in other resources and not been able to find a solution or test to try. I've written an open 3D world renderer in Arduino C (I appreciate Arduino is really C++ but code is struct-based...
