Support,
I have TIDA 00293 and need to program it. But first of all I need to check that it is connected properly and operates as intended. I can connect to it using USB cable via LightCrafter program (see LightCrafter.png) and turn LEDs on/off.
However when using PrinterGUI software the USB cable alone is not sufficient and TTL-232R-3V3 cable is needed with the FTDI chip to launch the software (PrinterGUI.png).
Unfortunately I cannot set the image with this program although it does not show any error messages (via USB cable the original firmware image is reset to the the blank screen). When I disconnect the TTL-232R-3V3 from TIDA 00293 I get exactly the same result. Therefore I made a conclusion that both, the USB cable and the TTL-232R-3V3 cable are involved in the data transfer and it is not clear how exactly it works. The connection I used for TTL-232R-3V3 cable to J25 pins in the TIDA 00293 with the following sequence: GND->GND, RXD->TDI, TXD->TMS1.
I've checked also with another tool the HIDAPI Test tool (HIDAPI Test tool.png, don't mind the missing device because it was not connected when I've made the screenshot).
I am able to connect to the TIDA 00293 using USB cable but when I send the output or the feature report I always get the parameter size is incorrect (although I've use the examples which must have replied with the correct answer).
One more thing to mention is that I've tried to launch QT and build the firmware of the TIDA 00293 with the compiler but I get an error announcing that I need an old version of compiler 3.3.3, which I couldn't find where to download.
First question is: is the TTL-232R-3V3 cable connected properly, if not how should it be connected (I could not find explanations in the manuals of the particular meanings of the abbreviations in the electronic scheme)?
The second question is: how do I check that the device is connected and functions properly so that I can try to figure out how to program it according to the DLPC350 programming protocol.
The third question is: how the data transfer is done exactly, do I always need both cables or is it possible to configure it to function with only one cable for data transfer, if it is an USB cable how do I configure it to operate as a Virtual serial port?
Thanks in advance,
Almis
