PSoC™ 5, 3 & 1 Forum Discussions
Hello, I just got the CY3655 Dev-Kit and installed the current version of the PSoC Designer. I found the DrawUSB sample on the CD, but this is an old 2006 version, which needed PSoC 4.4. Is there an actual version of the sample available?
Thanks in advance

Show LessThe emerging market of home automation devices is encouraging application engineers to think of solutions that integrate number of features into a single system. Through their innovative ideas and forward thinking they try to come up with highly effective and reliable system. These system not only enable the user to access his home appliances remotely and automate his daily chores but also to think of a solution which addresses most of the his security concerns in minimum number of chips. This article discusses such a solution and is divided broadly into 4 parts:
1. Sensors
2. Communication between these sensors
3. User control and feedback
4. Security measures to prevent intrusion

Show LessIt's said that PSOC Creator is supported by KEIL,but now,we can't use "goto loop".How can we find another code with the same founction to replace it?

Show LessI am working with a product (lets call it a keypad) that uses the CY8C27643 as it's MCU and communicates with another host device over RS485. We have had problems in the field with communications between the keypad and the host device and determined that the baud rate of the keypad transmitter was off by ~3.5%. The primary clock source for the MCU is the IMO. I checked the clock divider settings for the UART and found that they were set correctly based on the expectation of a 24MHz IMO. I then measured the clock rate directly with an o-scope and based on my measurements and the divider settings I calculated that the IMO is actually running at 23.17MHz, an error of 3.5%. The PSOC technical ref manual states on pg109 that the IMO will be within 2.5% tolerance, so the MCU appears to be operating out of spec.
It looks like the only option right now is to try to adjust the IMO trim via IMO_TR. However we have many keypads in the field that have MCU date codes as early as 0543. The 0543 parts have an IMO freq of 23.75MHz and do not have baud rate problems. The date of the device we are experiencing problems with is 1043. So heres my question..... we have several thousand devices in the field, so how can we custom trim each device in a simple, expedient manner? Is there a programmer pod or software that will auto trim the IMO for me?
Thanks.
Show LessHi,
Our new design includes a cypress component and I have to program its EEPROM from the embedded software. Are there some source code using the ISSP protocol I can implement in our embedded microcontroler ?
Thanks

Show LessThe Controller Area Network (CAN) was first introduced by Robert Bosch to address the growing complexity of vehicle functions and networks. In the early days of embedded systems development, modules contained a single MCU, performing a single or multiple simple functions such as reading a sensor level via an ADC and controlling a DC motor. As these functions became more complex, designers adopted distributed module architecture, implementing functions in 2 or more MCUs on the same PCB, and using I2C or SPI protocols to communicate between these functions. Using the same example above, a complex module would have the main MCU performing all system functions, diagnostics, and failsafe, while another MCU handles a BLDC motor control function. This was made possible with the wide availability of general purpose MCUs at a low cost. Read the full article on ECN.
Show LessI need to generate a bipolar analog current source where I can control the amplitude, frequency, and pulse width. Is there an example project that will help me get started. I am open to using PSoC 1, 3, or 5. Thanks.
