12:55 AM mrdata||: you wont need the bus much if you have a good cache
07:05 AM anonnumberanon: rue_morh okay cool. I'm still a bit fuzzy on HAL vs other libraries. Reading a large intro PDF on the stm32f103
07:07 AM anonnumberanon: It's awesome except for the fact they use a dev board that is quite advanced and don't like not having just the bare minamal, as in chip, oscillator and a few caps.
07:08 AM anonnumberanon: Maybe I'll try and setup gdb for it but I hope I can, I only use the little usb stlink device. I think it could be a usb to uart but not sure.
08:58 AM horohoro: hello everyone
08:59 AM horohoro: glad to be back here
09:35 AM rue_mohr: hi
09:36 AM rue_mohr: mrdata||, but when you have 4 cores executing programs that mostly just move memory around, and threading that keeps causing cache flushes
09:37 AM rue_mohr: anonnumberanon, thought you said blue pill?
09:37 AM rue_mohr: anonnumberanon, want help?
10:02 AM mrdata||: rue_mohr, if programs just move memory around, why dont they use dma for that?
10:19 AM deshipu: mrdata||: isn't that basically what the MMX commands are?
10:21 AM mrdata||: idk
11:14 AM anonnumberanon: rue_morh it's the blue pill that I have
11:15 AM anonnumberanon: I have to work but yes I'd like some help when it comes to it
11:15 AM anonnumberanon: The stm32f103c8t6
05:56 PM anonnumberanon: What flashing board do you use for blue pill rue_mohr?
05:58 PM anonnumberanon: This toolchain seems reasonable
05:58 PM anonnumberanon: https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Programming-an-STM32F103XXX-with-a-generic-%22ST-Link-V2%22-programmer-from-Linux
07:31 PM rue_mohr: mrdata||, most software just moves memory around, games dont
07:31 PM rue_mohr: anonnumberanon, I just got a flashing led working again
07:31 PM rue_mohr: do you have anything working yet?
09:27 PM mrdata_: in case you missed, robots falling over, https://www.youtube.com/watch?v=g0TaYhjpOfo
09:28 PM zhanx: ok rue_mohr second print is 1/3 printed
09:28 PM zhanx: printer
09:29 PM zhanx: i realized on this the j head error
09:30 PM zhanx: after these upgrades i will be done ish
09:30 PM zhanx: fyi your gear box was already done
09:31 PM zhanx: i modded it for a tension pully
