Hi Ben, Thanks for the reply. I've managed to get the whole project working, but I'm not sure I quite understand what I've done :? Initially I had a 20MHz crystal and everything (BME280, GPS, KS0108 gLCD display, 4 x K-Type thermocouples and a quad encoder) all worked 100% - just that the gLCD was v...

OK thanks for your reply. I changed the 20MHz crystal to a 64MHz crystal and the screen's response is much better now. But now the GPS module thats feeding data in at 9600 baud doesnt work. I've checked the Mirochip data sheet and it's possible to achieve 9600 (well 9615 baud) with a 64MHz crystal. ...

Was there ever a solution to this slow operation of the gLCD screen? I'm busy with a project using a gLCD (KS0108) and am having the same problem. Everything works fine, except the screen updates very slowly.

Thanks, got it working.

Hi, I haven't done much work on Flow Code for a while. I've just started with a new project and am now suddenly getting a lot of errors when trying to compile to .hex. They all end with "Autoclose turned off". The latest program one was working fine until I added the GPS component. Even wi...

Hi there, I would like to set up Timer0 of a PIC18F46K22 as a counter. In order to do this, I need to set some timer0 configuration bits in order to configure the timer as a counter. I will also need to read the counted value from the timer register. I assume the only way to do this in flowcode is t...

Hi,

What is the process for installing FC8.2. Do I need to delete 8.1 first and then install 8.2 and then the 8.2 patch?

With NO jumper on A0, A1 , A2 the address is x3F (or 63 decimal) - this works 100% for me.

Hi Jorgen, It looks like you've added the I2C master component, but don't use it in the program, so its actually redundant. You can delete it and the program will still work exactly the same. I think the LCD I2C component has the built in I2C functionality without the need to make use of the I2C mas...

I've posted a FC that I quickly tested on actual hardware and works fine. I've always added a small delay before and after initializing a display to allow it to settle down before using it. I only do that once at the beginning of the program. Hope this helps...

It often gets suggested on this forum to included a 1 second LED flasher in your flowcode to make sure that your basic program, config bits and timing are all correct. Then one can have a look at things like hardware connections and components properties. That's about all I can suggest without seein...

Or is there maybe a specific version of the firmware (considering there are so many different versions) that the ESP8266 component works best with?

If you post your program here I can have a look at it as I've used those modules very successfully. Just check that you have the correct I2C address in the properties menu. I used 63 as the LCD address, Baud Select 400kHz.

Hi,

When I used the ESP8266 component in FC6, it was possible to modify the expected ESP responses in ESP8266 properties. In FC8 I don't see this option. How would I modify the ESP8266 responses in FC8?

Thanks

It appears as though

ClrWdt();

compiles without errors

If I disable all the clear_wdt(); then the programs compiles successfully.

Hi, I'm getting a compile error when I try to clear the watch dog timer with C-Code block. It worked great in version 6. I'm using: clear_wdt(); and get the following error when I try an compile the program in FC8: C:\ELECTR~1\PROJECTS\G_Lert\SOFTWA~1\V2>C:\PROGRA~2\Flowcode\Common\COMPIL~1\pic\batc...

Hi,

I am staring a new project and would like to make use of a colour display. I'd like to use a display that is somewhere in the region of 5-7 inches in size. Since flowcode supports quite a few displays, I was wondering if anyone has used a colour display that works well with flowcode?

Thanks

Thanks Benj, I've made some progress. It seems like it is looking for an initial state for %1, %2, %3, so if I manually type the following into the address bar (which clicking on the submit button should do): 192.168.4.1/process.html?s=1 then it responds correctly and thereafter everything works 100%.

Hi, The issue seems to be that the %1, %2, %3 variables (index.html) are not functioning. For example, when I click on the "submit", the "get" request is generated, but without the value for 's'... 192.168.4.1/process.html?s= is being sent, so the '0' or the '1' is not being atta...

Hi Benj,

Thanks for the reply. I've made the changes that you suggested, but the output is still the same. I've attached the FC8 file. Any more suggestions?

Thanks

Hi, I was reading the following blog as I have very little knowledge of web servers etc: https://www.matrixtsl.com/blog/internet-of-things-made-simple-example-of-web-page-controlled-relay/ and decided to have a go at it. I seem to be quite close, but the web page isn't quite behaving as expected. I ...

Hi Benj, Thanks for your reply. I firmly believe that due to the ESP32’s powerful functionality, there will be a large number of people making use of this chip and could possibly be of great financial benefit to Matrix to support it with FC. I for one have no intention of upgrading to FC8, but if th...

Hi guys,

I recall reading on the V7 forum (I think) something about upcoming support for the ESP32 in V8. Is this correct and if so, has there been any progress?

Thanks

Hi Benj,

Have you managed to make any progress on adding a function to the ESP8266 component w.r.t. to returning a string response from the ESP8266?
