Hi ,

I don't know if this is a bug, but i noticed that if the file name in the sd-card is longer then 8 characters
will return file not found .

Is there a chance we could fix this please ?

Hi, I am working on a project that uses ESP-Link it is possible to do outbound HTTP REST requests from the attached microcontroller but in order to communicate with esp-link data must be sent in SLIP protocol format. There is already an Arduino library for this protocol the name is el-client Availab...

hi For all those who need a network to serial bridge for your microcontroller here is the Answer "esp-link" this free software for esp8266 makes it possible to establish Telnet to serial connection, send commands to the microcontroller via it's HTTP web interface, flash connected AVR, ATmega & ARM p...

hi Benj, thanks for your quick reply. As I said I am just getting started what I want to accomplish is sending commands to my MCU via HTTP and telnet but before I start to build my flowchart I want to make sure that I can make the connection using the HTTP and telnet protocol so for now, I am experi...

Hi I am just getting started with this Module I would like to make a telnet connection it is possible using Arduino IDE but would like to make it with flowcode, I have experimented with the HTTP server example it almost works but the only problem is that the module closes the connection right after ...

Hi LeighM

Just found it, it was the buffer size increased it from 255 to 500 and everything now works as it should
You may also want to update the wiki example file with the one attached below.

Thanks very much.

Hi LeighM

Yes, it worked just incremented +5 the data pointer that was it so there is no bug.

Just another weird thing I noticed the MCU stop responding if the 2 disabled macros are enabled
don't know why.
Thanks for your help

Hi LeighM

Thanks for the info , will try it and keep you posted.

hi LeighM Thanks for your reply, in the Wiki example the data pointer is being set in the GetTcpDataPointer component macro, datapontr.png I understand this can be set manually but it would require Wireshark to see the data. I don't know where the data pointer has to be set to get the page1 string o...

Hi
Am I doing something wrong or is a component bug?

Although I use flowcode V7 , the new Flowcode V8.1 might have the same bug!

Hi I am playing around with the ENC28j60 I have flashed the example to an Atmega 328p from the wiki page I can Ping the module, view a web page but in the wiki example there are 3 pages I can only access one of them the problem is that Read TCP document request is not returning the “/page1” string, ...

Hi
Have a lot of these GLCD's with the controller SANYO LC7981 240x128 Dots

is there a chance this will be supported in flowcode 7 ?

Thanks

hi Steve, thanks for your reply I will try running it in safe mode as you advise, but I don't think that is the problem because if I use an older flowcode.exe file everything work well again and as I mentioned with the new exe file everything works well until it is time to download the hex to the MC...

hi Benj

I have discontinued this part of the project because all HTML code is stored
on the microcontroller and have a lot of limitations + it's a bit slow to execute so
I am trying something else

my problem was 99.99% because of the different build version that I was using.

thanks .

A bit old but i don't think that is the problem.

hi Benj

Just check the EXE file but the same thing it stops and has to close .

Hi Just found these 2 bugs in the esp8266 module 1. GetFrimwareVertion returns the string "ALT+GMR", not the actual version. 2. CheckTCPServerIP will freeze the mcu and will not return any string . ( only when connected to an SSID in AP mode works OK ) I think these bugs are due to esp8266 firmware ...

Hi Benj

Thanks for your reply, No the chip does not program Flowcode compiles to hex ok then a window pops up
"Connect Your Arduino" after pressing ok Flowcode stops responding and has to close.

I will try the new EXE and let you know.

Thanks

Hi I have just updated to the latest flowcode 7.3 Now have a problem when I try to use AVRDUDE (USBASP) to burn the Atmega 2560 as usual flowcode stops responding and has to close after doing some investigation i found that the problem is in the new FlowcodeV7.exe I can confirm this because when I r...

Hello, For all those that want to use the $5 AVRDUDE or ( USBASP ) here is what i have done some time ago to get it work with Flowcode 7 . There are 3 files and some configuration involved in this which are avra.bat , avrc_asp.bat and the .fcdx file of the chip you need to flash with AVRDUDE , the m...

Hi My STM32 Dev Boards are finally here :) Image 1.png And I now can start experimenting with the intent of porting my project from Arduino to the STM32F407ZG I know that the STM32 is still work in progress , and that I have already asked this question before but before starting I would really like ...

Hi John , Good morning I think that 0xEC is referring to address 0x76 , and 0xEE to Address 0x77 , let me explain in order to communicate with a device via i2c we need 3 addresses , the main address of the device for example 0x76 , when this address (1110110) is sent on the i2c bus the device with t...

Hi Ben So I have had a very quick go with the BME280 Sensor what i have done is Initialize -> Read HumidityFloat -> Float to string -> Send via RS323 , Same thing for the temperature and Pressure but without initializing . I can see the sensor on Address 0x76 But the results i am getting are a bit c...

Hi Benj

That is very good news , I will try it as soon as i find some time

will this work on the stm32 ?

Thanks very much

Hi

Just noticed that flowcode 7.2.1 is out , what is new in 7.2.1 ?
