ANNOUNCEMENT: Chinese holiday Oct 2-7

For your information, the week of 2 to 7 October is a holiday in China. Some Espressif employees will still be browsing the forums every now and then, but responses may be delayed until after the holiday.

Re: I2C example wanted

Yes, there are. The app team is adding drivers to esp-idf which are more highlevel and multi-thread compatible where it makes sense. SPI and I2C drivers will also arrive in esp-idf in due time.

Re: Support for IPv6, including mixed IPv6/IPv4 operation?

As far as I am aware, LWIP is capable of simultaneous IPv4 and IPv6 operation. LWIP is included as source code in esp-idf, so it should be possible to replace it with something else. I can't comment on the ease with which you'd be able to do that, though.

Re: Support for IPv6, including mixed IPv6/IPv4 operation?

LWIP actually already supports IPv6; at the moment, it's just the DHCP bit (server as well as client) that aren't IPv6-compatible yet. Support for complete IPv6 is planned, but unfortunately I can't tell you the timeframe on that.

Re: [Q] user/custom space addr room on the SPI Flash for data

Hmm, interesting point. I'll see if I can take it along in the development process of the partition API.

Re: [Q] user/custom space addr room on the SPI Flash for data

Sure. I see you also have code to add partitions. Be advised we at Espressif meant the partitioning scheme to be static, as in: it will describe the flash layout during the lifetime of a device and messing with the table is only something that happens in very specific circumstances. Not sure what wi...

Re: Problems linking with math library - undefined "__fpclassifyd"

Can you file an issue on Github for this? Sounds like the script that generates the rom ld file may have skipped over this because of the double underscore.

Re: I2C example wanted

Have you enabled the clock to the I2C peripheral? Something like

Code: Select all

SET_PERI_REG_MASK(DPORT_PERIP_CLK_EN_REG,DPORT_I2C0_CLK_EN);
CLEAR_PERI_REG_MASK(DPORT_PERIP_RST_EN_REG,DPORT_I2C0_RST);
(off the top of my head) should do the trick.

Re: [Q] user/custom space addr room on the SPI Flash for data

Our plan for that is that eventually, you can do something like: int partitionType=0x12, partitionSubtype=0x34; size_t size=partition_size(partitionType, partitionSubtype); char *partData=partition_mmap(partitionType, partitionSubtype, 0, size); for (int x=0; x<size; x++) printf("Byte %d of the part...

Re: IDF refresh process

I'm sure Kolbans way works perfectly fine, but it's the equivalent of demolishing the entire flat and then rebuilding it when you want to change the curtains of your appartment :X As far as I know, a 'git pull && git submodule update' should do the trick.
