Re: KS0108 gLCD working slowly

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...

Re: KS0108 gLCD working slowly

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. ...

Re: KS0108 gLCD working slowly

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.

Compiling errors

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 without usin...

Assembly code

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.

Re: I2C LCD printing strings

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...

Re: I2C LCD printing strings

Re: I2C LCD printing strings

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...

Re: I2C LCD printing strings

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.

ESP8266 RESPONSES

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

Colour graphic display

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

Re: Switching an output with ESP8266

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%.

Re: Switching an output with ESP8266

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 attached to the URL.
