Hi all
I test the board Duinomite-mini and the module MOD-TC with the sample program from the manual
10 PIN(1) = 0: PIN(2) = 1
20 SETPIN 1,8 'SCK
30 SETPIN 2,8 'CS
40 SETPIN 3,2 'MISO
50 SETPIN 4,8 'MOSI we do not use this
60 PIN(2) = 0 'enable MOD-TC
70 PAUSE 1 'wait MAX6675 to settle
80 TEMP = SPI(3,4,1) 'read first 8 bit
90 TEMP2 = SPI(3,4,1) 'read next 8 bit
100 TEMP = TEMP *256 + TEMP2
110 TEMP = TEMP \ 8 'remove last 3 bits
120 PRINT "Temperature = ";TEMP*0.25 '12 bit 0-1023.75C
130 PIN(2) = 1 'disable MAX6675
140 PAUSE 300
150 GOTO 60 'read again
It works on the connection with the corresponding ports over the GPIO connector.
If I but try it over the UEXT with the changed Pins
ARDUINO.D10 → PIN(7) → UEXT/SD.CARD.SS
ARDUINO.D11 → PIN(8) → UEXT/SD.CARD.MOSI
ARDUINO.D12 → PIN(9) → UEXT/SD.CARD.MISO
ARDUINO.D13 → PIN(10) → UEXT/SD.CARD.CLK
So for Pin 1 then Pin 10 clk
Pin 3 Pin 9 MISO
Pin 4 Pin 8 MOSI
Pin 2 Pin 7 CS
It is no working
Hello,
I wonder do you have SD card plugged when testing? Try to turn off the SD card from the menu accessed by "config" command.
