RE: MpicoSys TCM solution - nicolaszin - 01-11-2016 Hi, I have bought a 10 inch Pervasive Display, and connected to it via a USB2TCM board (and a TCM board to the display). So far so good. I manage to send picture to the screen (by uploading image to the USB "storage device"): But 1 time out of 3, I got this kind of image: My questions are: - is this supposed to happened? (yeah stupid question) - is there a way to know when it fails? (i don't see a "report" file in the usb drive :-( ) - is there a way to avoid it? also not related but: is there something "easy" to ideally connect a TCM to a Raspberry Pi (to send the image and be able to fetch the error). Regards, Nicolas Zin RE: MpicoSys TCM solution - Charming - 01-11-2016 Dear Nicolas Zin, Great work of the weathercast template! You can remove the USB2TCM board and refer to the USB2TCM Github for controlling 10.2" TCM with the Raspberry-Pi. There is BUSY signal to verify if the Device(TCM) is idle for sending command/data. Best regards, Charming Su - FAE@PDi RE: MpicoSys TCM solution - nicolaszin - 01-11-2016 Ok, so basicaly you suggest to play with the SPI interface. I will have a look and come back maybe with questions :-) Thank you RE: MpicoSys TCM solution - MichalK - 01-11-2016 Dear Nicolas Zin, If you could answer the following questions, you would make it easier for us to help you. - What is the exact product code of the TCM and the USB2TCM you are using? (Example product codes respectively: TCM-P102-220_v1.1 / USB2TCM_v1.1) - How do you generate your epd images? Do you use the MpicoSys Convert Tool? - You wrote that you upload images to the TCM via USB2TCM. Is it executed by a script or manually? Do you remove the old image before uploading a new one? Do you download the image from the USB storage device and then use it again? - What operating system are you using?

I leverage heavily the project found on https://github.com/Ceruleous/EPaperReader It helped me a lot to: - connect to the correct GPIO - and write the code to upload the images. I had to change a bit the code because I am using a 10.2'' not a 7'' so the code looks more like Code: def upload_image(image_data): |
