Pod configuration

Pin Description

The signal pins of easyDSP pod are shown below . Its pin pitch is 2.54mm.
For easyDSP connector in your board, please use either BHS-01-10P or XG4C-1031 connector.
Note the arrow mark on the connector.

/BOOT, BOOT pin

These pins determines how MCU will boot after reset, either boot with flash to execute user program or boot with bootmode to conduct RAM booting or flash programming.
These pins are not used at all (= no signal output) when MCU boot with flash.
They are active only when MCU boot with boot mode as below :

MCU
Used
boot pin
boot pin operation

C2000
XMC4
TX, TXZ3
/BOOT

/BOOT pin becomes low when MCU reset.
Around 1sec after MCU reset is released, /BOOT pin becomes open and no signal output.

STM32
BOOT

BOOT pin becomes high when MCU reset and keeps high during boot mode period.
BOOT pin becomes open and no signal output when exiting boot mode (= exiting from Ram booting or flash dialog).

AM2x
TM4C
MSPM0

BOOT

BOOT pin becomes high when MCU reset.
Around 1sec after MCU reset is released, BOOT pin becomes open and no signal output.

RA
RX

/BOOT

/BOOT pin becomes low when MCU reset.
RA : /BOOT pin becomes open and no signal output when entering "Command acceptance phase" during boot mode.

XMC1
PSOC4
LPC1x00
not used

not used

You can use MCU pin that connects to /BOOT or BOOT pin in your application progam if you follow below guidline.
Please check the voltage level of the MCU pin at the beginning of your application program (input IO mode as reset default). Once the voltage level of the pin becomes high or low depending on used boot pin, you can set the MCU pin accordingly and start to use.

LEDs

There are two LEDs to indicate the status as below. Both LEDs should be ON during easyDSP operation.
'DSP' or 'MCU' LED is on : MCU controller board is now power supplied (= #4 pin is live with 3.3V)
'USB' LED is on : easyDSP pod is well connected with easyDSP PC program. It's ON when easyDSP project is open, OFF when easyDSP project is closed.
Note) for optic cable easyDSP, DSP LED of PC side pod and USB LED for MCU side pod are not working.

Connection to and Disconnection from PC and MCU

Don't make any physical connection or disconnection of easyDSP pod to/from PC and MCU during MCU operation. It makes unintentional reset to MCU.
In case you can not avoid connection/disconnection during MCU operation, connect PC first then MCU, disconnect MCU first and then PC. This will minimize the chance of unintentional reset to MCU.

Connection to PC

If possible, please connect easyDSP pod directly to PC (not via USB extension port). And please use the new USB cable to secure its connection quality.
