PSoC™ 5, 3 & 1 Forum Discussions

Curious why this is occurring -

Regards, Dana.

Hi,

 I am looking for a PSoC for Li-Ion battery charging, discharging and BMS integrated application. I found PSoC 3 and PSoC 5LP based design for single cell Li-Ion. However it is only for charging and BMS of single cell. I also want similar on the load side of the battery that can be programmable. Also for a 4S1P or 5S1P battery pack with 24V/upto 6A max output. Kindly advise. 

Thanks

Hello PSoC users,

I am attempting to import an old project (2008-2012) that is supposed to be in the release phase and working, the project contains some components in the TopDesign but no trace for them under Genereated_Source folder. I tried regenerating the APIs so it creates those files under Generated_Sources but I did not get the assumed behavior after successful compilation. My question is:" Does regenerating  those missing components APIs affect my application or not ?"

Please note that:

• I use the PSoC Creator v2.2 CP6, as was mentioned in the project.h file header, as the last version used to build the project.
• I did not update the components on the TopDesign when prompted.

If you got experience dealing with old PSoC 3 projects resurrection, or if my description is not quite clear, please consider contacting me.

Thank you in advance,

Hello @MotooTanaka san,

As a continuation to the topic and project (attached in the thread) discussed a while ago, at this link.

I have two RTC firmwares, one without any ErrorDetection and the other with ErrorDetection (return statements in failures) in both the i2c_write_reg() and i2c_read_regs() functions.

Both the firmware work properly when there are no error conditions, especially when there are no connection issues with the RTC module.

But when the RTC module is disconnected during reading,

1.) The firmware PCF8563_Clock_UART.zip, which does not have any error detection or return error statements in the functions, recovers on any number of connect-disconnect instances of the hardware as mentioned in the RTC_NoErrorDetect_ProperRecovery.txt log file attached.

2.) The firmware PCF8563_Clock_UART_Error_NotWorking.zip, which has an error detection and return error statements for different APIs in the functions, does not recover back from the errors and fails forever (unless Hardware Reset) as can be seen in the RTC_ErrorDetect_NoRecovery.txt log file attached.

So, I was wondering if anyone can help me with how to implement an error code returning function that can actually recover back from the error condition (instead of failing indefinitely) and read back from the RTC again.

PS: I am aware using goto statements may not be the best way to get to a pre-defined firmware location.
PPS: The log files are attached as a log_files.zip (since .txt files cannot be attached here).

Yash

PSoC Creater 4.4 will program my CY8KIT-059.
However, Programmer 4.00 will not recognize the device.
However, Programmer will detect my CY8KIT-147.
What must I do to get Programmer to detect the CY8KIT-059 ?

I'm making improvements to my custom Term component.

I've got a modest work-around to determine if the host port is open.  I'd like to improve upon that.  

The goal:  Quickly determine if the Host port is open and ready to comm or if the host port is closed and DO NOT try to transmit.

Note: USBUART_CDCIsReady() will not work in this instance since it will always return 'not ready' if the Tx buffer is full OR if the HOST port is NOT opened.

I've gone through the datasheet, the USBUART component source code, and made some experimental code.  All to no luck.

Is there an API or Global variable that indicates whether the Host port is open?

Thanks in advance for your help and suggestions.

Hello,

I'm a PhD researcher in University Nacional of Cordoba, Argentina. As part of my research, I'm investigating the PSoC 5LP CY8C58LP Switched Capacitor and Continuous Time Block and I have some questions regarding the capacitor values in the TRM.

This is the figure 28-1 of the TRM showing the complete block:

In this diagram, the values the capacitor named “comp” are between 1.24fF and 5pF but in table 28-3 the “comp” capacitor values are between 3pF and 5.1pF.

Are the values in the table for all possible configurations of the SC-CT block? Or it can take other values as well?

On the other hand, I’m analyzing the variation of the capacitor values between the output driver and the negative input terminal (feedback capacitance) depending on the mode.

For example, if the block is used as Continuous Time Transimpedance Amplifier (TIA), this is the capacitance values table 28-9.

Nevertheless, not all those values match the ones in figure 28-1 or combinations among them. Are there any other capacitors than the ones in the figure?

Even more, in the figure 8-13 of the CY8C58LP family datasheet, there’s a C2=1.7pF capacitor that is not in figure 28-1 of the TRM.

Is the figure 28-1 incomplete? If that´s the case, can you share with me a more complete diagram of SC-CT block where I can see all capacitors?

Thanks in advance.
