PSoC™ 5, 3 & 1 Forum Discussions
I am using the PSoC 1 CY29466 MCU. I discovered the internal ADC do not have enough resolution or linearity for my project. I decided to use ADS1211 ADC. It takes a three wire SPI interface. Can you point me in a direction for examples to write and read from the external ADC?
Thank You,
Philip
Show LessHow do you reset a 16 bit timer... meaning I am using the capture interrupt and at a certian condition I need the timer to reset. Is it possible?
Show LessHi,
I have an array defined in C:
char return_data[32];
I need access to this from an asm routine. What do I need to add to the .asm file to inform the compiler / linker of the existence of return_data ?
Many thanks

Show LessHi,
I am using an ADCINCVR to measure an input signal of 0-5V. I am able to get the ADC working, but am observing high amount of error in the ADC readings. What could be the possible reasons for the error?
Thanks in advance for any leads.
Show LessHello
The filter is a lowpass filter 64 taps (about 5% overshoot)
on the picture we have :
signal3 : 300kHz DMA clock (input and ouput of the filter are DMA)
signal4 : The duration of an ISR program that changes the input value of the filter from -100 to 120 and back, to perform a signed square signal
signal5 : the sign bit of the filter output (bit 7 of HOLDAH register)
CH2 (red analogic curb) : the output of the filter with an offset of 128 ==> 8 bits DAC
We can see that at the end of the rising edge of CH2 (and before descent) the sign bit of the filter is swicthing to negative values generating a bug in the response of the filter.

Show LessHello,
I am new to PSoC and trying to use the EMIF but I cannot find a good documentation for it.
I didn't even found a Component in the Component Catalog to add for EMIF. There is one in the installation folder, called psoc\content\cyprimitives\cyprimitives.cylib\cy_emif_port_v1_0 but it doesn't appear in the Component Catalog.
How do I add this component? Or is there any other way of using EMIF?
Show LessHi everyone,
I try to read a 0 to 2.5V with the ADCINC14, i use the REFMUX for read 8 port, and I use the external ref (P2[4], P2[6]).
Analog Power : SC On/Ref High
Ref Mux : P2[4]+/-P2[6]
VDD : 5V
P2[4] : 0V
P2[6] : to a ref 2.5V
Problem; can't read more than ~15818 counts...
2^14 = 16384
ref 2.5V/16384 = 152.588uV
15818 * 152.588uV = 2.414V <- this is my problem, if the input is 2.5V or greater never read more than this.
Thanks for reading and helping me 🙂
Show LessHeloo,
suppose i want to generate Sine wave using VDAC , 1 vpp, Then what would be the max freq of the signal i can get from this component, What is the speed in the Spec of VDAC , Is it related to freq or any otherthing??
Any document which explains this will be good
Thanks in advance
Show LessHi all
Please help me with some question
1. is possible make Schmitt triger with Creator components ?
2. is possible make ADC component with direct 8bit digital output bus ? (like data bus DAC component )
3. Creator 2.0 will be free for all user like Creator 1.0 ? or info about it or release date.
Many thanks info
Kamil
