movax posted:I hate MSP430s. Used them in space applications (at the time, it was the 'lol FRAM is invincible logic') and ran into the same issues as above, but due to I2C. No built in CAN controller also sucked. FRAM is destructive reads, so IIRC, at least the FR5969 had a stupidly large amount of die area spent on capacitance to help not corrupt itself upon power loss. What kinda cool space stuff did you work on? Is CAN-bus used for space applications too? Selklubber fucked around with this message at 18:44 on Aug 8, 2021 |

movax posted:Mostly CubeSats / small spacecraft, and then one deep-space mission before everything ran out of money. People are making rad-tolerant CAN transceivers now, so it’s gaining a bit of traction with the newer players. Other common space architectures are SPARC, and a few folks are getting ARM and RISC-V up-to-snuff to get flying. POWER of course is represented — RAD750 runs both Curiosity and Perseverance. Oh that's cool. I like reading about space computers and stuff. I mostly worked with PLCs, and worst case if you gently caress up the programming remotely you have to take a plane to the other side of the country to fix it. Must be exiting/assclenchingly to make stuff that can't be easily reprogrammed.
