Eclipse Environment: AVR Microcontroller Hobbyist Seeking ESP8266 Embedded Programming Guidance

Question

Hello. I am a hobbyist programming avr microcontrollers in eclipse environment. I fancy esp8266 programming but directly embedded microcontroller in the module. The problem is that I am unable to get eclipse to program esp8266 and I have not found a detailed description of how to do it. I know...

It is worth taking an interest in the ESP competitor, the new Realtek system - RTL8710.

Thank you, my friend, for the information that there is competition for esp but I have two such modules and I would like to use them. Maybe a colleague can tell you more about RTL8710. greetings

As for ESP, here: there is a good starter course for LUA and Arduino.

SDK configuration instructions included with toolchain + Eclipse for Windows: http://www.esp8266.com/viewtopic.php?t=820. There are quite a few examples in the package.
Personally, I prefer Code :: Blocks: http://tomeko.net/other/ESP8266/native.php.
They say that the grass is greener on the other side - arduino may not suit you, but the SDK has its problems like incompatibility between versions, which made the version change something so that the project working with SDK 1.4.1 does not compile on the go with SDK 1.5.0 etc. - these are minor but annoying problems.

I found some interesting information here: Link . From the first comments: you need a JTAG interface for programming, ESP8266 can be programmed via UART. The interesting thing is that this chip has Flash built in, unlike ESP where I have concerns about the quality of the external Flash memory.

However, I am convinced of the arduino. Mainly due to the simplicity of installation, in addition, I can see that arduino for esp has an additional advantage that my colleague Ostrythomasz writes about.
greetings

edit.

How in Arduino Ide to use uart2 for communication, e.g. with a sim modem?

ostrytomasz · Answer

ESP also has a version with built-in memory - ESP8285. I would have concerns about the built-in memory, as neither for RTL8710 nor for ESP8285 I can not find information about the number of write or retention cycles. In the case of external memory, even if the memory is a fake, it can be replaced for pennies (winbond memory: 100k P / E cycles, 20 years of retention), in extreme cases use FRAM memory.

@ostrytomasz - and fram has no read operations limit? In fact, the read operation destroys the written information, so each read means at the same time a re-writing of the same value, which means that the write limit may decrease due to the readings. However, while the built-in memory is convenient, as much as the factory gives, we have. In the case of the external one, we give as much as we want.

henryxxl · Answer

For me personally, I miss some information about esp8266.
I just put the first page in html and esp

I have a question if my colleagues have an idea how to solve my problem? I want to save contacts to eeprom via the website but I have no idea how to do it.
I read in the esp specification that the second uart is only for preview.
Greetings.

I read about the extremely low number of write cycles in ESP-01 modules - it will definitely be better in the built-in one. Thanks for the info about ESP8285 - I didn't know about this system. My question - is it possible to block flash reading in it as in AVR?

ostrytomasz · Answer

10 ^ 14 ... 10 ^ 15 cycles. At 1 million cycles per second (probably a rather wasteful estimate, considering that the chip has some cache memory), this is 30 years of life. @henryxxl: Lots of contacts? Maybe the emulated EEPROM is enough: If the external EEPROM is I2C or SPI, not UART. If you want to do something closed, the arduino is probably not suitable:

henryxxl · Answer

I've seen examples of how to write and read eeprom, but I don't know how to do it with a page in html yet. The first page in html is esp, that's why I'm still gray in these topics so far it's only avr c.
The number of contacts is a maximum of 60 and it can be without names, but only numbers to then read them and send text messages.
I did something like this on atmega32 + fifibom g510 modem but I liked esp and I see potential in configuring the device like routers.
I did not know that esp has emulated eeprom (what is its maximum drinkability?), Maybe a better idea would be to use an outer cube but it's still too difficult for me.

Configuring ESP to work in eclipse :P I recommend it works As for reading, it is not possible in the traditional way in these systems greetings
