The character repository contains the byte binary codes for each character (note that each character takes up two elements in the array). Characters are printed from right to left on the 14-segment displays (so the first character in byte1 will end up in the rightmost display). You store whatever you want to print in byte1, then run i2c.writeBulk(byte1) to write it to the board’s internal RAM and therefore to the displays. Right now the code is set to cycle through all 36 characters, but you can change that to whatever you want.
We are trying out your code but have not had success displaying characters. A question: where did you locate the i2c port number value? I have looked all over and not found that documented. I’m curious how you found it.
Actually we did get this code to work. Again, my question is how did you determine the i2c port number to use?
Also, whatever function we use to read the pot on the analoginput, we get large values, in the range of 208-224. I was expecting (as documented) to 0 to 5, at least using getvoltage function. Have not used analoginput before so seems I am missing something…
Github is down right now, be patient. I don’t have the code they posted, but in the mean time, you could try out the library I wrote (soon to Github`d)…
Yes, I understand the port number is hex 70. My question is how you determined the value is 70. Did you find this in some documentation, or code or online? I have not been able to find this information and I want to know how one comes by this port number value.
