jaywar Posted February 2, 2007 Report Share Posted February 2, 2007 So I added a little juice from my power supply (10v ac) and I got the LCD working (thanks to help from stryd_one). So I went onto the next step and tried to upload the sid application. When that finished (I had to turn off the "automatic" mode in MIOSStudio in order to get it to finish the upload) the LCD went back to my old problem of the squares across the top row (as if MIOS wasn't installed, but it is). Any ideas on what I did and what I should try? Tried turning the power on/off but that didn't do anything. If I'm using the 18F4620 pic (from smashtv: BSL 1.2, MIOS 1.9c), could it be that I need to hook up the I2C board I made (I was waiting until I got the core and sid working but maybe that's not correct and would fix this?). Thanks for your help! ??? Quote Link to comment Share on other sites More sharing options...
moxi Posted February 2, 2007 Report Share Posted February 2, 2007 hi,you don't need to hook up anithing to make your pic workin right.MIOS seems to be not installed correctlyfirst, use the "wait for upload request" and smart mode to upload the MIOS (turn off your core, click on the "start" buton, then turn on your core, the upload of MIOS will begin. one time it's finished you should see on your screen "MIOS 1.9c ready"then turn off the "wait for upload request", then start the upload of your app...hope that will help... ;) Quote Link to comment Share on other sites More sharing options...
jaywar Posted February 2, 2007 Author Report Share Posted February 2, 2007 ??? Thanks for the suggestions... it seems to be something stranger (or perhaps this is documented somewhere else on the forum?) problem than that. It's working again. This morning, I decided to plug it in and see what happens, and sure enough, it's showing "Ready" again on the LCD. Could it be somethng to do with restarting my computer or something else? Not sure what's going on. I'll post again if it happens and what I did to get it to work again. Thanks again for the help. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted February 2, 2007 Report Share Posted February 2, 2007 I had to turn off the "automatic" mode in MIOSStudio in order to get it to finish the upload) ..... I'm using the 18F4620 pic Ahhhh.... The 4620 has a bug in the serial peripheral which means that MIDI can get scrambled. This EUSART bug means that the IIC_MIDI module is a must!If you check this page IIC MIDI Module and search for the part about "Default Tx Redirection" you will notice that you need to have the correct ID to use it by default. What ID did you select when buying from Smash?I'm a little concerned about the screen not working though... Might want to revisit that one once the MIDI interface is sorted, maybe uploading MIOS with the dodgy midi has busted the chip up, it might need to have MIOS uploaded again.

moxi Posted February 2, 2007 Report Share Posted February 2, 2007 ...and you have to use the last version of MIOS studio, be sure it's the beta 7_4 that you're using.. Quote Link to comment Share on other sites More sharing options...
