PSoC™ 4 Forum Discussions

Hi everyone:

I'm using PSoC 42 BLE kit to develop a controllable current source output. some questions on IDAC component remains unclear:

1. is there any method to control the polarity of IDAC(current sink or source), for  example: software method using some functions, (p.s. I know PSoC 5LP can do that, but seems that in PSoC 42 hasn't got such functions)

2. as I know, the current source will usually have two output pins, as the graph shown below, however the output of the IDAC just has one pin, so is the another pin should be connected to the GND?

Appreciation for the help...

As a part of a validation process of a PSOC4 device i am working on, i will be needing to check corrupted code on flash.

I am using a bootloader app to update code via CySmart.

I would like to check the bootlader app checksum test, by writing to some arbitrary flash location (by that corrupting the checksum). and restarting app.

How can i do that kind of writing to code location?

Hi friends

I am trying to develop a simple 5Mbps simple RF linke using FSk modulation. I have made PSoC4 : 4200 BLE family a candidate for it and now I am trying to figure out if I can disable the "BLE baseband peripheral" section in "Bluetooth Low Energy Subsystem" and just use the GFSK modulator and demodulator of the BLE subsystem?

All helps are appreciated in advance.

Hi,

We understand that PSoC4 Em_EEPROM component uses internal flash.
How long does it take to read the written variable?

// EEPROM Rad Function ：

eepromReturnValue = Em_EEPROM_Read(i*4+12288, wrkbuf, 4);

//The above 'i' is up to 1024 in the for-loop

//Amount of data : 4Byte x 1024

It takes 30 seconds to complete the above process.

I understand that it takes time to write variables,
Does it take time to read variables too?

You have a video of this board http://www.cypress.com/video-library/PSoC/cypress-psoc-4200l-audio-solution-introduction/480396

and have sent me firmware, etc in the past, but how do we obtain the board?

I want to create simultaneous iBeacon & Eddystone Beacon using PSoC4.

The plan is the dynamically update Advertisement data after every advertisement period in my case it is 150ms.

Took reference from Dynamic broadcaster project and I am able to achieve it. Attaching the source for it.

But I need it to be as power efficient as possible. What should be the best approach to do it?

One option is to after advertisement is finished I update the Advertisement packet and put system in deep sleep. Then again wake up and repeat after each advertisement.

Is there any reference code available to do so?

How do I periodically wake up the controller from standby and go back to sleep? Using some timer or are there any events generated by BLE stack that I can use?

I am expecting no substantial increase in current compared to regular advertisement and CPU in deep sleep.
