I can't read tempreture
Hi, When I connect the K- Type termocouple, the screen shows preheat 0.00 c, the problem persists when I change the termocouple directions. I use MAX31855.
My Arduino code starts as below ;
// Comment either one the following #define to select your board revision // Newer board version starts from v1.60 using MAX31855KASA+ chip #define USE_MAX31855 // Older board version below version v1.60 using MAX6675ISA+ chip //#define USE_MAX6675
// ***** INCLUDES ***** #include <LiquidCrystal.h> #ifdef USE_MAX31855 #include <MAX31855.h> #else #include <max6675.h> #endif #include <PID_v1.h>
What other line should I change other than the lines above? I am using code v.1.2 board 1R80. Best regards.
May I know when was this board purchased? We have since long stop selling 1R80. That is the only section of code you need to change to use the 1R80 board.
Hi, I use Gerber file and I produced pcb myself. When I checked the A1 pin with an oscilloscope, I could not observe the clock frequency. arduino clock does not generate signal. If I ask you, can you send me the code and library files that you are sure it works?
The posted code in this repository is the one last I have tested with V1 of the controller. The libraries for the MAX31855. I didn't touch it since then. Probably it's just a hardware connection issue.
