Re: Clock Speed
Yes, the error seems a little anomalous. We will look into it. However, as W4GNS has pointed out it would help to post some additional code that generates the error in your use case. Thanks...

Re: Digitaldiy
What's happened to the site? Have you tried contacting Graham? It's a real shame if it has all gone. Perhaps try "wayback machine" internet archive?

Re: Default Variable Assignment
It's a fair question. In the example you have given x could be anything. It most likely state would be "0" *but* then again it might not. It's easy to miss an initialisation in the code. But the warning should catch them... > ... and just to be REALLY clear, my use of "RHS" was NOT how the Urban Dic...

Re: Default Variable Assignment
Just to be clear dim x as byte will generate a hint "x is never used". As Jerry points out, it's not an issue unless you use "x" on the right hand side of an expression. dim x as byte dim y as byte y = x will generate a warning that "x has not been initialised" and dim x as byte dim y as byte = x wi...

Default Variable Assignment
I've decided to post this on the forum as it's a new feature of the compiler that I know a number of users have requested in the past. From 2.2.3.3 onward you can now declare and initialise variables at the same time. Some examples include: // Strings... Include "string.bas" Dim message As String = ...

There's been a shortage of virtual toilet paper - when it abates you can have a key!

Re: ST7565 GLCD Support
Yes, I have found it useful in the past to do this on smaller devices ("spread" the data bus rather than use a contiguous set of pins on a single port). The speed really isn't an issue. An LCD refresh is slow enough that you won't see any difference. I've tested this in the past. With respect to Ran...

Re: ST7565 GLCD Support
I have just tested the above code on real hardware and it works as expected (see image). For those people who have a Firewing board with LCD, here is the code I used: Device = 18F25K22 Clock = 64 // configure options... #option LCD_DOGM = DOGM_163 // 3 line #option LCD_INTERFACE = 4 // 4 bit data bu...

Re: ST7565 GLCD Support
I don't have any tested code for Swordfish but I do have some Swordfish code which I ported over from Firewing (which 100% works) so it may work for you or at least get you started. I have attached the modules you need and here is a simple program which uses them. Pay particular attention to the opt...

Re: ST7565 GLCD Support
Apologies. I just looked at the controller datasheet. So that appears to leave three options: (1) find a GLCD that utilises the parallel bus for the ST7565R or (2) use a different (supported) Swordfish driver for a GLCD with parallel bus (KS0108 - tons of devices, well tested under swordfish) or (3)...

Re: ST7565 GLCD Support
Having a *very* brief look at the ST7565R datasheet, the device can be run either parallel or serial.
Code: Select all
P/S = “H”: Parallel data input/output.
P/S = “L”: Serial data input.

Re: ST7565 GLCD Support
Just looking through previous posts, I see where you got the driver. However, you state you need a ST7665R driver. Certainly without this, your code will not work.
