mutantcamel1979 Posted June 8 Share Posted June 8 Hi I have just received an Hex-TI-r and I can't get the thing to work. I am getting a red power light on the top board and a green and red light on the board underneath. I have tried multiple hexbus cables without success. I turn on the Hex-TI-r, then connect the hexbus cable, then turn on the CC40 and all I get is the I/O prompt on the CC40. I have to unplug the hexbus cable to gain control of the CC40 where I get the error 255. I tried wiggling the contacts and also separating the 2 boards and slotting them back together. None of the lights flicker when I turn on the CC40, so appears not to be communicating with it. I have tried pressing the reset buttons on both of the arduino boards and also tried it with my other CC40, but it makes no difference. I can attach photos of the Hex-Ti-r as it may have got damaged in the mail. If anyone has any ideas I would appreciate any help. I don't want to throw the thing in the trash...

mutantcamel1979 Posted June 10 Author Share Posted June 10 **Update I managed to get the the HEX-TI-r t work** It was a combination of a loose connection between the 2 arduino boards and using a hexbus cable the wrong way round! It is a nifty little thing and hope to use it with my CC40 and TI74 in the near future... 2 Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted June 15 Share Posted June 15 It is a game changer for the CC40 for sure. Sadly though, there is very little programming activity happening for that little machine although I have to admit that it's tough to come up with interesting programs on a 32 character one line display... 2 Quote Link to comment Share on other sites More sharing options...

Turtles has been considering using his CC40 as his calculator of choice in his HS math classes. . .especially with something he can save his data/equations/programs to now. 1 Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted June 16 Share Posted June 16 Cool! Will they allow it though? The teachers might think it's got some advanced AI or something 🤣 1 Quote Link to comment Share on other sites More sharing options...
