Jumpers on the board LPC-H2148

Development Boards MicroMod

Hello,

The board LPC-H2148 from Olimex have 2 jumpers with the name:

  • L_E

  • DBG_E

What is the function of every jumper?

I think that the Jumper DBG_E is for debuger, but is necessary to programm the uC using the JTAG?

Thanks!

You need to check them in the schematic against the data sheet, and see what functions the pins they connect to perform. DBG_E probably enables the JTAG, you need to disable JTAG to use ISP with the UART.

Leon is correct about the DBG_E jumper. If you have L_E jumpered, then you can turn on/off the LED that is connected to P1.24.
