chartreusemntmn: Alright I'll take a look into it this weekend. I've not been looking at it recently, but I'll see if I can find a better way of doing it03:14
chartreuseI was assuming that LPC meant low-power controller03:14
chartreuseSince it's not the main processor, but on the mainboard03:15
chartreusemntmn: For the keyboard I think the main thing needed is some signal from the LPC saying the system went to sleep or power off. 03:15
chartreuseThen I could easily make it sleep03:15
chartreuseOr we could do a watchdog from the LPC to the keyboard, say every 5s it sends a message and if the keyboard doesn't get it it can assume the system is powered off03:16
chartreuseThough differentiating standby and power-off would be nice so that I could change the menu so that pressing Circle-1 will wake from standby rather than restarting the system03:17
swivel"Amember of the Philips low pin count family, the P87LPC769 offersprogrammable oscillator configurations for high and low speedcrystals or RC operation, wide operating voltage range,programmable port output configurations, selectable Schmitt triggerinputs, LED drive outputs, and a built-in watchdog timer."03:30
swivelfrom: https://www.futurlec.com/Datasheet/Philips/P87LPC769.pdf03:30
swivelsounds like LPC = low pin count03:31
chartreuseLPC = low pin count is the name of the bus used on PCs though. It's basically a cut down (4-bit) ISA bus03:36
chartreuseI don't think the one on the iMX8 is particularity low pin count. I'd count a low pin count microcontroller as having 8 or less pins03:37
swivelthat doesn't preclude Philips using the acronym for their "low pin count family" of chips03:37
chartreuseYeah03:38
swivelim just referring to the historical origin of the name, since nxp acquired the family from philips03:38
chartreuseAh didn't know that03:38
swiveloh i see you joined after mntmn mentioned it03:39
swivel11:54 < mntmn> dates back to Philips... https://en.wikipedia.org/wiki/NXP_LPC03:39
chartreuseYeah I have that in my logs just missed it XD03:40
chartreuseI was there but disconnected for 5 minutes since I was messing with my network cables03:40
chartreuseShould have know because of the LPC800 which is/was the only ARM microcontroller in a DIP package (DIP8)03:41
