02:32 AM wirts-leg: i haven't yet had the need for a dedicated programmer

03:06 AM polprog: i think
03:06 AM _ami_: wirts-leg, long time ago.. where have u been living? under the rocks?

03:08 AM _ami_: lol :)
03:09 AM wirts-leg: pretty much yea lol
03:10 AM polprog: but i like avrs, they are so simple :)
03:10 AM polprog: and some pics are 8 bit too
03:11 AM Haohmaru: many pics are 8bit
03:11 AM Haohmaru: i have more fingers than some pics have RAM
03:12 AM Haohmaru: that programmer looks like a roll of insulation tape
03:12 AM Haohmaru: great design!
03:13 AM polprog: mike the led guy made a rant video yesterday about it
03:13 AM polprog: he uses a ton of simple pics do to tasks like receive serial and control some led drivers
03:24 AM wirts-leg: mike the led guy? is this a youtube thing?
03:40 AM polprog: wirts-leg: mikelectricstuff
04:18 AM Emil: polprog: the icd4?
04:18 AM Emil: polprog: just watched it
04:18 AM Emil: throroughly enjoyed and agreed with every single point
04:18 AM Emil: marketing people should not design products
04:19 AM Emil: wirts-leg: mike's electric stuff
04:26 AM _ami_: Emil, that aussie guy?
04:26 AM _ami_: mike
04:32 AM wirts-leg: I don't see much about LEDs on his channel.
04:34 AM wirts-leg: Here's one I did a few years ago. https://www.youtube.com/watch?v=WoOkIKVKPSs
04:37 AM wirts-leg: Sadly the source code was accidentally overwritten while I was working on a different program to run the device. One that doesn't react to music but offers different visual effects. I ended up saving the files to the wrong folder.
05:02 AM wirts-leg: anyone ever hear of nerdkits?
05:10 AM wirts-leg: hi remkooo1

05:27 AM wirts-leg: hi remkooo
06:00 AM Lambda_Aurigae: wirts-leg, heard of them..never touched any...too pricy
06:14 AM Lambda_Aurigae: they also claim to be for beginners but I don't see any beginner avr tutorials on their tutorials page..no blinkylights...no simple usart comms..
06:15 AM Lambda_Aurigae: their source codes include some libs of their own but the source links don't include links to those libs...at least not quickly easily found.
08:09 AM noHitW_work: there's a new series from ST http://www.st.com/en/microcontrollers/stm32h7-series.html?querycriteria=productId=SS1951
09:40 AM Snert: it's vaporware.

04:08 PM thardin: hi. I'm looking into bootloaders for atmega128 for loading over rs-485. any tips?
04:08 PM thardin: I found the multidrop one, but it's not quite what I'm looking for since it requires extra pins
04:09 PM thardin: on the connector that is. I only have power + rs-485
04:12 PM thardin: power can be cycled. so just a timeout in the bootloader would be enough
04:16 PM LeoNerd: What sort of timing are you thinking?
04:17 PM LeoNerd: Is this a multimaster half-duplex setup? Can the node to be bootloaded speak?
04:18 PM thardin: I'm thinking a rather long timeout due to latence. on the order of ten seconds
04:18 PM thardin: just two nodes on the network. master and the avr
04:19 PM thardin: might want some basic stuff like reading back what's stored in flash too
04:19 PM thardin: I believe atmel has a protocol ready for it, but I forget its name. could be a good magic word to websearch for
04:22 PM thardin: AVR109
04:32 PM thardin: found some leads, will have to dig further into them tomorrow
04:33 PM thardin: best would be something standard that's well used and tested
04:40 PM thardin: looks like the watchdog can be set to 8 seconds. good enough
05:52 PM Lambda_Aurigae: avr109 is serial bootloader but not specifically for rs-485.
