LPC1114FN28 first program running OK!
So I modified the blinky program to blink a LED driven by pin PIO1_8 (LPC1114FN28 pin17). Then I downloaded the program, set ISP pin from ground to Vcc, then pressed reset to run the program.
blinky(LedPio18, 100, 200, 1000000); // Led driven by Port 1, Pin 8
Everything went smoothly. The LED blinks and the scope show what is expected.
So far so good. Time to take a break.
