Problem finding how to set GMT #3

Closed nikkisstuff closed 5 months ago

nikkisstuff commented 5 months ago

I have built the clock and it works flawlessly But i am not very good with coding please could you tell me what i need to change to configure GMT

Thanks

ansemjo commented 5 months ago

That is wonderful to hear! ☺️

The timezone is configured in main.c with a setenv( ) call: https://github.com/ansemjo/chronovfd/blob/c2c7b33cb1a6d2b7752a84c55f2d39de58642ff3/firmware/src/main.c#L162-L165

According to the linked CSV file you should simply change that to:

setenv("TZ", "GMT0", 1);

Thank you i will try it now

I made the changes and set it for GMT/London from the list in the link but its not worked. I took the picture at 3:51pm

That looks like your clock isn't fetching any time at all, not just a timezone issue ...

nikkisstuff commented 5 months ago

that did not work i am going to reflash with unmodified firmware to see if that makes a difference

nikkisstuff commented 5 months ago

After uploading the unmodified firmware it had moved +1 hour

ansemjo commented 5 months ago

Which, again, indicates that the timezone is applied correctly but the clock doesn't fetch the current time from NTP.

Have you tried opening the serial console to the ESP32? There are a lot of logging messages, including success or failure of NTP updates.

Maybe you also need to update the NTP server addresses. If you're in a firewalled network, connections to external NTP servers are sometimes not allowed and you need to use a specific host on-campus or something like that. https://github.com/ansemjo/chronovfd/blob/c2c7b33cb1a6d2b7752a84c55f2d39de58642ff3/firmware/src/realtimeclock.c#L170-L173

As an aside: I am working on-and-off on the next iteration of this clock, which will fetch the current time from FM radio stations via RDS. No internet and no timezones required. Or at least I hope so ...

wat. I'm afraid there is some kind of over- or underflow happening here.

If you can live with your clock always updating from NTP when plugging in power, you could replace the check entirely and just always force an update:

Ive Just remembered I had a problem with the platformio.ini the espressif/toolchain-riscv32-esp @ 8.4.0+2021r1 is not available I had to update it to 8.4.0+2021r2-patch5

nikkisstuff commented 5 months ago

I left the clock powered up over night and this morning it looks to have synced up with the ntp server. i left the sync delay as 5 in the firmware
