Is it possible to advertise while in Deep Sleep mode?
I read somewhere that Advertising runs off the ECO clock, which is a HFCLK. Any time a HFCLK is running, we cannot obtain Deep Sleep. With that being said, my answer should be no. However, i'm wondering if there is a way to either use a LFCLK for advertising instead (and also for scanning). I'm running a battery operated system and really need to save some power!
As a fallback, I do know that there is the ability to go into Deep Sleep mode between advertising intervals. I'm not sure how to do this yet, but i'd rather sleep the entire time i'm advertising, rather than every interval.
Thank you for any thoughts or advice!
Show LessI'm developing a GAP peripheral. I want to put the MCU to deep sleep while BLE is advertising. Can use BLE to wake the MCU up when there is a connection? Thanks in advance. I really appreciate your help.

Hi,
I'm using a PSoC 4L running of 1.8V.
- power-scheme: 5V (with soft-start / will "ramp up") -> Buck to 4.2V "SYS" -> LDO -> 1.8V
- the supply has a ~200mS delay before the 4.2V rail will be live, before that, SYS can be about 1.5V
Issue:
- seems like the psoc is drawing about 2-3mA immediately, even at 1.5V supply...
- Can I assume that it's drawing this while waiting for 1.72V+ VDD so it can start properly?
- Once the PSoC starts, would it be possible to achieve <= 1 mA current draw during a say 100mS period?
Thanks
David
Show LessHi Everyone
I need to let my PSoC4 CY8CKIT-049 kit communicate with PC through Ethernet. I have an SPI to Ethernet Converter Module based on ENC28J60. I am planning to make a customized PSoC Creator component named "TCP" for this project. I have just started up by creating a project in PSoC Creator (Please find herewith the attachment.). Would anyone like to share his/her experiences by giving some code snippets, documents (Mainly to understand TCP/IP, SPI and their interconnectivity) and module projects?
Thanks in advance.

Show LessHello,
I am trying to Interface two slaves with single I2C master with my own developed board which has on CY8C4245AXI-483 controller on it.
I have interfaced two I2C slave with single master, 1. PCF8574AT usd for interfacing 20x4 LCD, 2. DS1307 RTC. i have used 4.7K resistor to make I2C lines pulls up.
what i am trying to do is to fetch data from DS1307 RTC and displaying it on LCD.
At firmware side i am using SCB block for I2C master control. When i am running my code it sending data to LCD, and LCD displaying string properly, but i am not able to Read data from DS1307 and its gives constant data.
Interesting thing is that, i have make same setup with another general purpose board with same controller chip on it which has not DS1307 on it, i have interfaced it separately and my same code is working properly with this setup.
I am not getting any idea that why its not working with my designed circuit board.
Can anyone help me to over come this problem??
Thank you.
Show LessWe've been using PSoC Creator 4.0 for our BLE Broadcaster project. The option "Silicon generated 'Company assigned' part of the device address" is checked in the GAP settings. The BLE component version in the project is 2.10.
I recently ran a build of the same code using PSoC Creator 4.2 (loading the same project). It updated the BLE component to v3.51. I verified that all options in the BLE component are set the same.
Our problem is thus: The BLE MAC address is different (and constant) depending on which firmware image we load. That is, if we load the 4.0-based build we get one MAC address. If we load the 4.2-based build on the same device we get a different MAC address.
We are not writing a custom MAC address to user flash row 0. We'd prefer to not have to.
My understanding is that with the "Silicon generated 'Company assigned' part of the device address" option checked, the MAC address should be a function of various aspects of the die's manufacturing (X & Y location, wafer lot, wafer number, etc). If that is that case, then the MAC address shouldn't be changing.
Can anyone tell me why the address is different between the two compiled images?
Thanks for any insight you can offer.
Show LessHello,
I have integrated an I2C Bootloader on my Evalkit PSoC4000S (4045).
Now I am able to upload Firmware via I2C, respectively via "Bootloader Host" PC-Programm from Cypress and PSoC5 which transfers the Data via USB to I2C.
I am now looking for a Bootloader Host C-Programm/Code which is easly portable to simple MCUs (Arduino etc.)... is there already something available?
thank you.
Show LessOn-board our PCB is a CYBLE-022001-00 chip and a third-party WiFi-capable device. Is the Cypress EZ-BLE PRoC chip we're using WiFi coexistence-ready? If so, is there a guide on how to manage it?

(別途IDAC使用予定。"Enable compensation IDAC"をOFFにしております。)
シングルIDACモード時のCSXの動作での影響はどのようなものがありますか?
まだ、シングルIDACモードでもCSXは動作するのでしょうか?
デザインガイドを見る限り、CSXはIDACが2つ必要に見えます。
