Rusty, I’m having trouble communicating with the ATtiny via Arduino.
I have a Lumen, powered independently. I have an Arduino Uno, connected as follows:
Arduino Pin 13 (SCK) to the Lumen TEMP pad
Arduino Pin 12 (MISO) to the Lumen LED-PWM pad
Arduino Pin 11 (MOSI) to the Lumen SIGNAL pad
Arduino Pin 10 (RESET) to the Lumen RESET pad
Arduino GND to Lumen GND pad
I haven’t connected the Arduino 5v to the Lumen VCC 5v pad, I assume this shouldn’t be needed ?
I haven’t shorted the SJ1 jumper (assume this is if you want to send pwm direct to the A6211).
Arduino IDE is configured Board: ATtiny 25/45/85, Processor: ATtiny45, internal clock 1MHz, Port: Com6 Arduino/Genuino Uno, Programmer Arduino as ISP.
The Lumen is powered via an external supply, Arduino is powered via my laptop.
I load the standard Blue Robotics Lumen Arduino sketch into the Arduino IDE, press upload, it compiles ok but when it tries to upload I eventually get an error message “avrdude: stk500_recv(): programmer is not responding” (it tries 10 times).
Anything obviously wrong in what I’m doing ? Should I be able to upload this way? Should I be using “Burn Bootloader” instead of Uploading ? Do I need to use the Shell file ?
Any help appreciated !
