mikromedia 7 CAPACITIVE U S E R M A N U A L
The installed MCU (referred to as “host MCU” in the following text) can be
programmed and debugged over the JTAG/SWD compatible 2x5 pin header (1),
labeled as PROG/DEBUG. This header allows an external programmer (e.g.
CODEGRIP or mikroProg) to be used. To enable the JTAG interface, two SMD
jumpers labeled as JP42 and JP44, located in the PROG/DEBUG section, have
to be populated. These jumpers are unpopulated by default, optimizing the pin
count so that more pins could be used for a large number of onboard modules
and peripherals. Hence, SWD interface is enabled/supported out of the box.
If your MCU card has preprogrammed bootloader, MCU can be programmed by
using the mikrobootloader application. All the information about the bootloader
software can be found on the following page: www.mikroe.com/mikrobootloader
A switch labeled as SW1 (2) is used to specify whether CODEGRIP/mikroProg or
a third-party programmer is connected to the JTAG/SWD header.
The mikromedia 7 development board is equipped with the reset button labeled as
RST (3), located on the front of the board. It is used to generate a LOW logic level
on the MCU reset pin. The RST pin of the host MCU is also routed to the pin 1 of the
1x26 pin header (4), allowing an external signal to reset the device.

N O T EBefore usage, please check if the programmer pinout and the 2x5 pin header
pinout are compatible. Based on the used programmer/debugger tool
pinout, a coresponding addapter might be needed (e.g. mikroProg for PIC).
