First steps on mbed (great environment!)
I acquired a mbed LPC1114FN28 board including the DIP LPC1114. But my main focus is the nRF51822 chip that I have in a breakout board.
I removed the LPC1114 chip from mbed LPC1114FN28, and then I connected the SWCLK to SWCLK of the mcu and SWDIO to SWDIO of the mcu. Also I connected gnd and vcc to the mcu.
When connected to the laptop I can see mbed drive (ubuntu linux).
Using mbed site, I configured it for board redbear BLE NANO (it uses the same MCU) and wrote the following test program:
myled = 1;
myled = 0;
Build + drag & drop (no error)
I used a led in order to detect I/O changing but no pin (including the p0_19) is driven by the source code.
I also tried another program when selecting mbed LPC1114FN28:
myled1 = 1;
myled2 = 1;
myled1 = 0;
myled2 = 0;
None pin is “blinking”
(I have quite sure that the MCU remains with the original program (from manufacturer) that uses SDA and SCL pins to communicate with external device using i2c.)
So it seems that program is not burned on MCU
Main question: Can I use mbed LPC1114FN28 to program “external” M0 chips such as nRF51822?
