Problem when using with Arduino Nano to read temperature from LM35 #2

Closed ChetanAmrao closed 4 years ago

ChetanAmrao commented 4 years ago

I downloaded the repo to try the ADC_test.ino but I cannot see any SPI values on the serial monitor all i see is 0 0 for both channels

Do i need to make any changes to the program? my connections:

i have not used your same circuit i connected the miso, mosi, ss, 5v, gnd to the MCP3202 from the Nano

can you suggest anything? thanks

How have you hooked up the LM35? Have you got the MISO, MOSI, CLK and SS pins right?

thanks for the quick reply i am using a custom board so i made a wrong connection, should have checked that first before making an issue

i connected a pot to it and now i see 0-4096 range on the spi image

i have to find the same library for raspberry pi now, we can close this issue
