if found the solution before i saw your answer ^^ My complete code based on "RXC touch sensor Mux" : #define I2Cport S4 #define I2CAddr8574 0x40 // I2C Address pour 8574 unsigned byte WriteBuf[]={I2CAddr8574,0x00}; // adresse - données unsigned byte ReadBuf[]; // Lecture PCF8574 int RdCnt...

Hi there, i m experiencing some diffuculty to optimize my program. After i have read which button is pressed i ligh a led : switch(ReadBuf[0]){ case 8 : WriteBuf[1] = 0xf7; break; case 4 : WriteBuf[1] = 0xfb; break; case 2 : WriteBuf[1] = 0xfd; break; case 1 : WriteBuf[1] = 0xfe; break; default: bre...

You can see that it respect the drawing of matt. I think the pcb is ok, i would had so...
