Hi,
I am trying to port the simple WS2812 code found here:
http://wp.josh.com/2014/05/13/ws2812-neopixels-are-not-so-finicky-once-you-get-to-know-them/
I am trying this so I can easily modify it for use with the SK6812 driver:

I am trying to test it using an LED with a WS2811 driver:
https://www.adafruit.com/datasheets/WS2811.pdf
See my attached code, I cannot get the light to do anything.
Any help is greatly appreciated.
Regards,
Tom
Show LessI can not find the function in the C# API to send scan_request's. I need this function for a project from the university but i can not share the code, can you help me? thanks
Show LessGreetings,
I kind of thought that the pinouts of CY8C4146LQE-S433 and CY8C4146LQI-S433 would be identical, but it seems that they are not. Is this really the case?

Hi,
In order to operate PSoC4S with an external clock,
Enabled EXTCLK of Configure System Clocks.
Frequency is 24MHz
Accuracy is -2% to + 2%.
HFCLK set to EXTCKL
No error occurs after Build.
The clock of the SG-8002CE24MHSTB-L3 oscillator is input to P0 [6].
However, PSoC4 does not start after programming.
Are there any restrictions on how to use an external clock?
For example, are there any application notes listed?

I had designed UART Baudrate 115200.
and It's actual baud rate is 117647.
I had checked 1 bit time.
8.57us. It is 116686 bps.
PSoC4 has 2.5% Internal oscillator acuraccy.
Question 1 : Is that 117647bps always success UART communication for all temperature condition?
The opposite MCU has an oscillator attached. So the opposite MCU sends and receives UART exactly.\
Question 2 : Can I make UART baurate more accurate?

I'm long-term embedded, but new to PSoC's.
PSoC Creator 4.2 appears to offer two relevant Component options for multi-line LCD displays:
a) Parallel connection to an LCD equipped with an HD44780 controller
b) I2C bus with an LCD equipped with a PCF2119x controller
We need to be frugal with GPIO, so we can't dedicate an entire port to an LCD.
The market is heavily saturated with 4x20 I2C/HD44780 LCD panels, while a 4x20 LCD with I2C/PCF2119x controller seems rare. I'm using PSoC4 CY8CKIT-049 trying to incorporate PSoC4 / 4200M in my projects, so any guidance in this regard would be sincerely appreciated.
Show LessHello community,
I'm using the ADC, 12 bits with the psoc4 pioneer kit. The analog input comes from a potentiometer, the max voltage on the input pin is: 4,62 Volts (measured). I'm using 5 V for reverence. So I expect an output value of 3784 with this voltage. But the maximum output I get is: 3368. I've attached the project. The output is shown on a 7 segment display on an arduino multifunction shield. What is going wrong? Thank. Mark.
Show LessPFA Program in that code keyboard and mouse working but CapsLock LED staus is not working.
Please send any sample code which include Report Map of Mouse,Keyboard with CapsLock Led staus and System power button.
Show LessI have a firmware that fails performing the CyBle_Start() function on some platforms.
Using the same firmware, works on some platforms, fails on others.
During the intialisation, the CyBoot_IntDefaultHandler_Exception_EntryCallback() is trigged, while accessing to the 0x402E10D8 register.
(Writing 0058 to this register) using DEBUGGER, the area is full of FF FF (i suppose not mapped into memory)
I've done step by step follow up in assembly to find the <Faulty> condition. (Write access to register 0x402010D8)
I try to figure out, why such initialization failure.
Can it be related to the clocking of the IP ?
In order to have very low power, I'm using IMO 3 Mhz.
Thanks for your support.

Ce message a été modifié par : PHILIPPE BRESSY Modules : CYBLE214009-00 or CYBLE214015-01, got the same behaviour on both modules. The same firmware, work or does not work depending on platform. Works on one platform, then stop to work. Is there any 'integrity checking firmware' provide by CYPRESS, able to test the CYBLE214009/15 modules for internal failure ?
Show LessHi,
I ama beginner user of Cypress products and I need some help.
I would like to use the cyble 214009-00 chip in order to control 16 different heaters via Bluetooth.
I fabricate the heater myself. I need to give them 0.7 Amps and 1.2 V for them to heat up to the desired temperature. I will use 3.3v, 150mAh lithium-ion battery to power them.
I know I cannot draw that much current directly from each pin. so my question is what components I need to use ( like MOSFETs or bjt) in order to draw the needed current?
I can fix the cyble 214009 with the needed components and my heaters in one substrate at the end.
Can you please let me know if this is doable and how it can be achieved .
Thank you
