Have connection but data returned is rubbish. Any tips or clues gladly appreciated.
My code below is modified from Appendix D in Picomite User Manual
OPTION BASE 1 ' array will start with the index 1 DIM data%(2) 'array for receiving channel 1 data dim data2%(2) 'array for receiving channel 2 data SETPIN GP8, GP15, GP14, SPI2 ' assign the I/O pins, RX, TX, CLK PIN(27) = 1 : SETPIN 27, DOUT 'pin 27 ADC chip enable active low SPI2 OPEN 5000000, 1, 8 ' speed is 5MHz, 8 bits data PIN(27) = 0 ' assert the enable line (active low) SPI2 WRITE 2, 104, 0 ' initialise ADC channel 0 SPI2 READ 2, data%() ' get two bytes from ADC
SPI2 WRITE 2, 120, 0 ' initialise ADC, channel 1 SPI2 READ 2, data2%() ' get two bytes from the slave
PIN(27) = 1 ' deselect the slave SPI2 CLOSE ' and close the channel
'output to console ? bin$(data%(1)), bin$(data%(2)), bin$(data2%(1)), bin$(data2%(2))
