Re: DsPIC stops running if GLCD is included in the program

Hi Ben, I wish i had looked at using the logic analyser sooner. Using the EB076V1 component with the R22.Pmmc file for the display i have observed the following. Using an 8 bit PIC the display functions ok with the baud rate set to high or low. Using a 16 bit PIC at a high baud rate the display fail...

Re: DsPIC stops running if GLCD is included in the program

Hi Ben,

I will have a look today with my logic analyser and monitor the data going to and coming from the display when using an 8 and 16 bit chip using the same instructions and let you know the results.

Thanks

Re: DsPIC stops running if GLCD is included in the program

Hi Ben, The crystal speed is correct, it matches that of the crystal fitted. I have downloaded the latest pmmc file(uLCD-43PT-R44.PmmC) for the display and selected a EB076V2 display in Flowcode using the 16 bit chip. The led flashes now and i can display text on the screen however i am unable to di...

Hi Ben, Thanks for posting the article on using media files with the 4D display. I have used this type of display numerous times before with 8 bit pics, with no issues at all using images from the SD card in conjunction with graphics composer. As mentioned above as soon as i have tried to use a 16 b...

I have included two programs, one that works correctly for the "look for value" function and one that does not, however the one that does work has other issues of its own that are explained. A th...

Re: DsPIC stops running if GLCD is included in the program

Hi Ben, Wondering if you have been able to follow this up any further. If the display is powered up and nothing is sent to it, the 4D Systems splash screen is displayed. With the screen connected and the above program running the screen goes blank, as well as the led not flashing, so something has b...

RS232 send string

Hi,

I am working on a project and wondering with the send string command within the RS232 macro, is there any limitation on the length of the string i can send out? The data is entered in the format "\x97\x82". The length of the string i am using is 40 bytes long.

Thanks

Re: Problems using the "find" function with the circular buf

Hi Ben,

Thanks for this it works a treat :D

I spent a while looking through the help files and was unable to find any info in regards to entering the data in the format "\x67\xfd\x27". Could the help files for the circular buffer be updated to include this as well?

Thanks
