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, pseudo open state) when MCU boot with flash.
They are active only when MCU boot with boot mode as below :

/BOOT

/BOOT pin outputs low when MCU reset.
Around 1sec after MCU reset is released, /BOOT pin becomes pseudo open state but due to external pull up resistor, it becomes high status.

BOOT

BOOT pin outputs high when MCU reset.
Around 1sec after MCU reset is released, BOOT pin becomes pseudo open state but due to external pull down resistor, it becomes low status.

STM32

BOOT

BOOT pin outputs high when MCU reset and keeps it during boot mode period.
BOOT pin becomes pseudo open when exiting boot mode (= exiting from Ram booting or flash dialog) but due to external pull down resistor, it becomes low status.

/BOOT

/BOOT pin outputs low when MCU reset.
/BOOT pin becomes pseudo open when entering "Command acceptance phase" during boot mode but due to external pull up resistor, it becomes high status.

not used

 pseudo open state

 

The MCU pins connected to the /BOOT and BOOT pins can be used in the user program, as easyDSP maintains these pins in a pseudo-open state while the user program is running. However, no external output circuitry should be connected to these pins, as it would cause signal contention when the /BOOT and BOOT pins output their own signals.
 

LEDs

There are two LEDs to indicate the status as below. Both LEDs should be ON during easyDSP operation (not blinking).
'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.
        no special meaning to the color of LED.
 

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.
