wire library how to wait for slave to finish job arduino

flash led's so we know they're working Serial.println( 'setup(): Wire.begin() successful' ) Serial.println( 'setup(): Serial port open: 9600 baud' ) Int I2C_trace = true // serial out trace flags Void send_to_slave( char *calling_function, flash it's command led after receiving sda/scl each.ītw, except for the uno, i bought all new boards for this test.Ĭonst int I2C_due_1 = 124 // slave I2C addreessĬonst int int_slave = // number of times the slave decided to Master comes in on one side and feeds the 4 slaves off the other. it’s divided in half via a 4-position jumper. the due’s are a required interface to the 10.1' displays i’m using.įyi - the breadboard looking thing on the fritz is actually an 8-position dual-rowīarrier strip - radio/shack #2740670. I wish it were as simple as replaceing the due’s with mega’s to avoid the problem. the uno and mega have no problem replying.īoards are powered off the hp™ usb ports via sabren™ usb hubs. – upon receiving the request, replies with the number of times. – upon receiving the command, flashes the led. – sends a request to the slave asking it how many times it flashed. (number of times the slave flashes it’s led is up to the slave). – sends a command to the slave that instructs it to flash it’s led. The attached sketches, in terms if I2C call sequence, are literally cut’n’paste from Recent update to one or the other is causing the problem. i always update boards and libs when asked. That, during development of producton code, this has worked from time-to-time. “am i wasting my time?” if yes, i have to ask “why?” i’ve spent 3 years andĬonsiderable funds on the production code. i’ve included fully a executable test case. I know this topic has been beat to death.
