Re: Initial Test of Main V12.6 board
¿ªÔÆÌåÓýOk one more test you can run¡ The AUDIO HAT¡ and the RF board uses ¡°WIRE¡± (not ¡°WIRE1¡± or ¡°WIRE2¡±)¡ so you could build the control portion of the RF board and try that to make sure that ¡°WIRE¡± is working correctly.? I guess you could also connect to the ¡°RF CONTROL¡± connector on the MAIN board to a bread-boarded MCP27018 with address 0x27 (which is ¡°111¡± for A0, A1, A2) to see if it returns the part imitating the RF board.?? You just need pins 1 = SCL, 3 = SDA , and 5 = GND. ? ? Dr. William J. Schmidt - K9HZ J62K(J68HZ) 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ ?

Thanks Jack and Bill, Yesterday, I successfully ran the ASCII code. I2C device found at address 0x20: Front panel MCP23017 for switches 1-16? !So, it's between the Audio Adapter and the Teensy Audio Hat. Until they arrive, I will look into the PRCJ docs on breadboarding the Teensy with the Audio Hat to see if something turns up. Am I the only one that this happened to, not only that but two board sets in a row. John K1JO |
