Hi, I'm here to seek help.I would like to represent multiplicative inverse in GF(2^8), using textLCD in mCube cortex m4 with stm32407vg.I'll use functions, unsinged char xtimes(); and unsigned char inv(unsigned char a);And also, I want to represent r...

hmm...That's right, it's training board, I think.I'll use your method, like :"Original : 1" >> sprintf(buffer, "Original : %02x", operand);"inv : 8d" >> sprintf(buffer, "Inv : %02x", inv(operand);Then, the last task left for me is to properly connect...

I can't proper link about mCube micro processor, so I attach photo of it.It's made in Korea, so you may not know.

I changed the way I had it in mind: using 2 buttons on the keypad to increment/decrement each value and display the inverse directly on the textLCD or 7-seg.1) How can the result be displayed if I use sprintf()?2) The input/output device is mCube mic...
