So Ive chosen to use a spark core as the heart of a project i am currently creating but have stumbled across some problems:
- I have 4 DC brushless motors where the ESC’s wires have been modified so only the signal wire is coming into the spark core and the motors are powered by a 4 cell LIPO. The ESCs are from
however as the spark core runs at 3.3v im wondering if im going to have problems, ive looked at the spark shield shield for the 5v conversion but as i need to run 3 additional sensors all on I2C the D0 and D1 pins i believe must be reserved for them.
Ive tried running a for loop incrementing the value written to the signal line and got nothing back, however if all 4 motors were attached all motors save the one i was trying to interface ran but i think this was some sort of variable overflow as i was writing 0-1800 to the signal line and i believe pwm values are 0-255.
Any advice on whether im going mad or my core is likely to catch fire is appreciated:)
Thanks for the help
