@_discord_710531555734454393:t2bot.ioredman_iu2kwo The rest of reverse engineering has been done by me, the opengd77 people and others 17:08:59
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Yesterday I tried again to see if I could fix the 600Hz offset on the MD380, but I had no success 17:09:37
@_discord_710531555734454393:t2bot.ioredman_iu2kwo However I can confirm that the VCXO bias is applied correctly, I checked it against the original firmware patched with md380-tools 17:10:25
@_discord_898135641471217684:t2bot.ioadf7021 Nominate openrtx for the ham radio software prize 17:11:49
@_discord_898135641471217684:t2bot.ioadf7021 Like I did 17:11:52
@_discord_898135641471217684:t2bot.ioadf7021 How do you know? Would be nice to measure actual voltage. 17:12:51
@_discord_710531555734454393:t2bot.ioredman_iu2kwo I looked the values of the DAC registers 17:16:38
@_discord_710531555734454393:t2bot.ioredman_iu2kwo md380tools allows you to inspect whatever memory address you want 17:16:50
@_discord_710531555734454393:t2bot.ioredman_iu2kwo And it also allows to dump the HR_5000 registers 17:17:07
@_discord_898135641471217684:t2bot.ioadf7021 So same DAC value for both firmwares? 17:23:38
@_discord_898135641471217684:t2bot.ioadf7021 Interesting 17:23:43
@_discord_898135641471217684:t2bot.ioadf7021 What if the alignment is different? 17:24:12
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Which alignment do you mean? 17:25:55
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Yes 17:25:59
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Observed at the dac registers 17:26:12
@_discord_898135641471217684:t2bot.ioadf7021 12b mapped on 16b, left or right aligned 17:26:17
@_discord_710531555734454393:t2bot.ioredman_iu2kwo It's already ok 17:27:11
@_discord_625397837785595942:t2bot.ioBastien ON4BCY That would be why Module17 have a hard time decoding my MD390 ? 17:27:33
@_discord_710531555734454393:t2bot.ioredman_iu2kwo It may be 17:28:28
@_discord_898135641471217684:t2bot.ioadf7021 So if that part is fine, hr_c might have wrong config? 17:28:55
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Yes. And I have to check this oart 17:29:38
@_discord_710531555734454393:t2bot.ioredman_iu2kwo * Yes. And I have to check this part 17:29:47
@_discord_710531555734454393:t2bot.ioredman_iu2kwo Even though some registers are already correct 17:30:24
@_discord_625397837785595942:t2bot.ioBastien ON4BCY If needed, I can be a beta tester 17:41:11
@_discord_898135641471217684:t2bot.ioadf7021 You can be an alpha dev instead 😄 17:42:38
@_discord_625397837785595942:t2bot.ioBastien ON4BCY Not enough knowledge for this 17:43:20
@_discord_625397837785595942:t2bot.ioBastien ON4BCY I'm learning but it's like learning a big thing at once 17:43:33
@_discord_771492214743367688:t2bot.iokc1awv I know that feeling 17:44:02

@_discord_598674410429480964:t2bot.ioonemikedelta By saying firmware, do you mean original correction is hardcoded in firmware? Doesn't it have a calibration values ? Maybe it is writing the original one to initialise but then correct it using calibration offsets somewhere else in the code, did you checked that? I hope we are not overwriting that values when we flash openrtx 05:11:30
@_discord_898135641471217684:t2bot.ioadf7021 on6rf i might get your radios today. Woooohoo 05:15:16
