Tutorial - SparkFun Blocks for Intel® Edison - Pi Block
about 4 years ago
There's a Fritzing diagram in the C++ Examples section of this tutorial, but I don't see the Pi Block in the Sparkfun Fritzing library. Am I just overlooking it?
I've got the MAX31855 hooked up, and am requiring jsupm_max31855. I see that the library is setting the chip select to low before the read, but I get a 0 for the temperature value. If I ground the CS pin manually right before I attempt a read, the Edison (through the Pi Block) reads the temperature fine. In the LCD tutorial it didn't look like you had to do anything special with the CS pin with the ILI9341 Module, is that correct?
The MAX31855 source: https://github.com/intel-iot-devkit/upm/blob/master/src/max31855/max31855.cxx
Update: I'm using the Adafruit MAX31855 breakout because Sparkfun's was on backorder at the time of my order. I saw this morning that it was back in stock so I ordered one and I'll see if it works any differently.
Thanks for the help.
Awesome, thanks @ShawnHymel . How slow is "super slow"? I'm trying to read from a MAX31855 breakout board. Do you think it will take several seconds to read the value?
Is there an example anywhere of using a SPI device with this block?
No public wish lists :(
