Thank You Kersing, Thats exactly what im looking for.

Time to do some reading

Hi Ben,

Yes, Its the ESP28266 WLAN i wanted to take a look at.

Thanks

Chris

How would i look at the source for a specific component?? When i goto build, view c. Notepad pops up and in place of c code i get instead sinething like you do not have permission. I cant remember the full text as im not home right now.

Hi Ben, Thank you for your reply. In notepad++ this is an example of what i get when opening the above file. $‰L ‘Éi¼ 2áÇ—n%Y{Íҍ8~A?¾`èdùãøwõãKÏLðü]zWÞߣJN¹åúÃjýa1µËýmóiµù4w?*f²)³Šà|–UK0Î’gîwSSdÞù¤0KÁpÞÔ5SѸ±óùÿùAþm¦fœ`:_ÁQVÄí•{-ÒÕ°®J qYwªâ‹ùñ%É5Ûõ°]jg#…LScÒRü‡•è,EÃOÂüS˜“ð9›W™d>.qÙဿÌb2™Š¥“ÝX“o...

Hi, I was hoping to look at what commands you are sending to the ESP8266 wifi module in the attached component file. I tried to open it in notepad but its just jargon. When i look in the customise c option in flowcode itself i can see only this // Read Server IP // Call Component Macro: data=WLAN_ES...

This little module looks quite interesting. I was wondering if i might be able to get a pointer. I would like to use the modules as slave devices connected to a router which is connected to the internet. The router will be setup for port forwarding allowing me to communicate with the slave devices c...

Thanks guys,
I will get an 8mhz crystal and try again.
Maybe that will simply solve the problem

This doesnt really help me much, i dont understand it. Thats why im using flowcode.
Flowcode usually sets up all of this sort of thing itself.

I am trying out a new chip, PIC24FJ256GB106. I have set in the config to primary oscillator HS, and enabled PLL. I am using a 16mhz external crystal. I have an LED blinking on and off at 1 second intervals, but to get the correct timing i have to set the frequency in general options to 21Mhz This is...

Hi steve, thanks for your reply. It appears to be the OFF calculation in the pressure formula causing problems. The result being given is just too big for the ulong variable to hold and results in a negative number. I assume a float variable wouldnt be able to hold this value either?? Im using a pic...

Hi, i am playing with a ms5611 pressure sensor. In the calculations it requires int64 variables. However flowcode only gives options for int32, i.e ulong.

Does this mean that its not possible to use this sensor with flowcode??

Hi

This thread seems to have all the info you need to do this.
http://www.matrixmultimedia.com/mmforum ... 618#p22616

Here is my program. Not sure if it will help to find the problem. The program just shows the init function for the SSD1351 OLED Display.

I have sent the program via PM. Thanks for taking a look at it for me

I have found this thread which describes the issues im having.

Will my fix be the same??

Hi i am having the exact same issues with the 24FJ256GB206. Would the solution be the same here also.

Im am keen to find out if this also fixed the display fault aswell as i cannot get my display to work at all over SPI but using pic18 it works flawlessly.

I am using the trial version of v6.0.7.

Hi I am trying out the new v6 demo. I am trying to use the spi to drive an oled display. The display has a SSD1351 Chipset. I seem to be having problems though. Pin outputs are not responding as they should. i.e i have 3 pins that control dc, reset and cs. Reset needs to be high in operation but whe...

Thanks for your replies.

How would i go about retrieving the HTML files from the SD card?

I would also like to use pictures in the webpage. Is this possible. If so any pointers on how to do it?

Hi I am looking into creating a wifi webserver. The webserver would display sensor data on a webpage in an internet browser. I would like to use the hi link RM04 for the wifi. I have never used wifi before so can i ask for some pointers on how such a system would work. I can then go and research bas...

You could have a look into the XRF by ciseco. I have used these many times and they are excellent.

All you do is send transparent data via usart and another Module can pick up the data and pass it to a computer terminal.

That makes sense, thanks for the explanation Ben

Thanks for the quick reply Ben. I just did some quick number and i think i am correct that a 1gb sd card has 2,097,152 sectors. I dont suppose its feasable to keep a count of how many sectors have been written too?? I dont fully understand how an sd card receives its data. Is it sequential?? For exa...

Hi,

I was wondering if it were possible to detect when an SD card is full using the FAT component.

I was looking to stream continuous data to a card but i would need an alert when the card is full.

Hi Jorgen

I did look at the DS32KHZ chip. At £7 each i thought i could find something better.

Thanks Ben,

I will have a try with timer 2, If I have no luck I will change the crystal to 19.6608Mhz.
