![]() ![]() This makes the linker happy and allows your program to build. the program file that contains your start and loop functions). The magic thing to know is that if any of your libraries use Wire.h or SPI.h you must Include them in the main source file (i.e. It’s one of those horrible situations where you have to know the “magic” trick to make it work. I’ve had this before, it is very frustrating. The compiler kept complaining about the Wire.h and SPI.h libraries not being available. I’d added the AdaFruit libraries and at that point my program broke. I’ve been creating a “Connected Little Boxes” driver for the BME280 environmental sensor (a personal favourite of mine). I hardly ever use them personally, I rely on people much cleverer than me to create libraries that I can use to talk to the hardware I want to use. They’re used by programs to communicate with devices over the I2C and SPI busses. ![]() Can you help? Thanks.The Wire.h and SPI.h Arduino libraries are kind of important. I’m probably doing something dumb, but I’m not seeing it. I can tell that something is happening, because the code completes in 3-4 seconds with no pin connections, it takes a bit over 60 seconds (as expected to scan 127 addresses with a 1/2 second timeout). I’ve tried it at 100KHz, 400KHz, 1MHz with the same result. Seed.PrintLine("I2C device found at address %x !", prAddress) Īnd the output when the Seed is connected (pins 12/13 on the pinout): Daisy is online I am starting to study the Wire library (no previous Arduino Wire library experience), I read some info taken from here. Int prAddress = (address < 16) ? 0 : address = _i2c.TransmitBlocking(address, &testData, 1, 500) Static constexpr I2CHandle::Config _i2c_configįor(unsigned char address = 1 address < 127 address++) Here’s my libdaisy version: #include "daisy_seed.h" Serial.println("No I2C devices found\n") ĭelay(5000) // wait 5 seconds for next scanĪnd the output (connected via A4/A5 to 3 daisy-chained (!) GPIO boards: Scanning. Serial.print("I2C device found at address 0x") Here’s the i2cScanner code from Arduino that I’m porting: #include įor(byte address = 1 address < 127 address++ ) I wonder if you’d have a look at my code? ![]() I thought I understood everything based on your comments, Stephen, but I’m having no success. ![]()
