PSoC™ 4 Forum Discussions
HI
Encountered this rare behavior in some of my devices running PSoC BLE 4200.
After sending the ACD module to sleep using XXX_Sleep()
On wakeup, using XXX_Wakeup, a conversion started, and conversion timeout occurred. (This later was followed by a watchdog reset...)
My question is why did this conversion take place? I did not ask for it.
My ADC is configured to HW trigger mode.
Thanks.
Show LessHello,
We know that the vref voltage of PSoC4000S CapSense Component depends on the VDDA voltage in Electrical Specifications of
the CapSense component datasheet and KBA220609.
If the VDDA changes the voltage from +3.3V to +2.6V, does the vref voltage follow the VDDA from 2.021V to 1.477V ?
Or It does not follow the VDDA because it is set the voltage when the CapSense_Start() function is done.
Which is correct?
Best regards,
Yocchi
Show LessDear all,
I 'd like to read characteristic value (say a sensor) from any of the peripheral devices according to their store address.
In a similar method of writing to a specific peripheral, could it be feasible with the same directed methodology used in the project, relaying the data back from a addressed peripheral to the Cysmart app?
Thanks

Show LessI can read hex file by programmer from flash, and compare it with the original, and find that the difference is in hex file all capital letters change to low case, for example , A changes to a, and B changes to b, and so on . At the same time, I also notice that the two files are different at the end of the files.
Show Less1)Why don't Flat spots occur when PRS is used?
Please tell this mechanism.
2)Why will the system use a direct clock as sense clock source that drives FSW by default?
(Why don't PRS used by default?)

Show LessI am having a heck of a time trying to clear an interrupt using the timer function on a TCPPWM component. The API states to use void ISR_ClearPending(void) but this does not appear in the API when i try to use it. The data sheet also talks about block/status register needing to be read/cleared, but doe snot tell how this is done. Could i get some help on how to do this properly. I will also attach my project for reference.

Our customer want to do underfill process in their PCB, could you help confirm the material is OK or not.
1. Zymet X2821 ?
2. Fuji UF317H ?
If not, could you provide the recommend underfill material.

Show LessWe've noticed that the CCCD values don't get reset with each new connection as required by the core spec (Vol 3, part G, 3.3.3.3). We are not using bonding in this case. Is this expected and we need to manage this manually? Or is something else wrong? The PDL version we are using is 3.0.4.
Show LessWe are testing DATA over BLE. it was running properly.
now we increased the payload size from 180 to 240 bytes at the android application end.
it stopped working after increasing the payload size.
It is not going into the state of "CYBLE_EVT_GATTS_WRITE_CMD_REQ".
it is always running into default case instead.
What might be the issue?
MTU size for attribute was 250 & changed to 450 bytes. But still no success.
