We've observed some flakiness with some core elements in the electronics of our robots:

[ ] the control panel is more fragile and needs a real PCB to be designed
[ ] the screen seems flaky, although most issues disappeared after resetting from the master board. We need to investigate its shock tolerance and sensitivity to power supply noise
[ ] the RAM on the master board is getting scarcer, we should investigate STM32F7 boards that would allow more RAM!

wrt point 3 (RAM getting lower), we can work on two other aspects:

1) Not over-provision thread stacks 2) Use "better" algorithms, unfortunately GOAP is quite memory hungry, maybe we can do better somehow.

msplr commented 5 years ago

don't forget, F7 has a more complicated memory architecture, which brings issues with DMA. I would wait updating.

SyrianSpock commented 5 years ago

I only mentioned "investigate STM32F7", don't freak out ;)

SyrianSpock commented 5 years ago

Not over-provision thread stacks

sure needs some cleanup

Use "better" algorithms, unfortunately GOAP is quite memory hungry, maybe we can do better somehow.

To be investigated too, this is an open question

Closing this as we are migrating away from the master board, so part 3 (low ram) is not an issue any more.

part 1 (control panel pcb) is done, and lives at https://github.com/cvra/front-panel-board
