Hi Karstikko,
We realize a change is not always welcomed but we feel it’s the best way to move forward. The new Workshop4 IDE supports 4 development environments, to cater for different user requirements and skill levels and the Serial environment you’ve mentioned is one of them. The Serial environment is basically a 4DGL application that uses a very simple protocol and makes the display act as a slave and it works well when the host and the display are in close proximity, i.e. both on the same application PCB or the distance of the host is within a foot or two from the display. In most cases this works real well as long as the transmission path is free of external noise. There are many high end commercial products designed by many thousands of customers using just the serial platform. If the environment is noisy or the distance between the display and the host is far apart, then why not use the Designer environment and roll out your own top notch serial protocol with many different levels of error checking? Many customers also employ this method. A good outcome for any application always starts by proper understanding of what’s required and a good feasibility study of all the factors involved. You mention you’ve used many of our displays (thank you for your support), but have you tried seeking help from our very helpful team of tech support engineers? If not, please do so, I’m sure you’ll find they’ll be able to resolve most of your problems.
Edit: I have just been informed that a user reported a crashing problem on Friday the 22nd of February, he was supplied with a Fix on Saturday the 23rd and Workshop was shipping with the fix integrated on Monday the 25th. If you are that user we apologize for any inconvenience. This problem was only limited to the Goldelox based displays and not on the Picaso.
