Hi ,

I have one question Is there any method to check if the device is returned from Backup Domain. I am working on device in which Backup domain is required for time tracking and other implementations.

I have looked into Technical Reference Manual Section for Backup Systems and Power Supply where I found VDDBAK_CTL for switching the Power rail between VDDD and VDDBAK.

I also looked into Registers Technical Reference Manual for Backup System Registers BACKUP_STATUS But it only tells the status of WCO and RTC_Busy not if system is returned from BACKUP domain

I also tried to look into Pdl reference manual no API found that could help me.

Kindly help me with the situation

请教个问题：

基于SDL7.3 验证Basic CAN功能，示例路径为：T2G_Sample_Driver_Library_7.3.0\tviibe1m\src\examples\canfd\Classic_CAN

CAN 接口可以正常的收发数据，但数据发送成功后，其发送完成标记没有置位，烦请帮忙确定下该问题原因；

debug过程截图如下：

我碰到了一个问题，我使用PSoC4的管脚下降沿触发中断(硬件电路是小于4.5V管脚会变低)，使用电源变动测试的时候，反复调整电压从9V→0V→9V，在第一次变为0V的时候我使用生成的stop函数关闭了中断，电源变动结束恢复到9V后我使用生成start函数开启中断时，会立即触发一次中断，这时候管脚状态并不是低电平，这是为什么？

配置是下面这样的，自动生成的函数是B_DET_Low_ShutDown_Stop和B_DET_Low_ShutDown_Start。

Dear Engineers,

I'm using own application based on TLE9879 Eval Kit Hall Sensor example. Everything is working flawlessly but I'm unable to reach declared motor maximum speed unloaded and loaded.

Rated loaded speed : 18000rpm

Rated unloaded speed: 22-25000rpm.

Actual unloaded speed with eval kit is 17220rpm.

Below are wizard parameters. Most change was achieved by maximum Ki Kp duty cycles which make sense, but now I'm unable to increase speed even further. Voltage is as per motor datasheet. Current also.

Any hint where to look now? Thank you

Hi I am trying to update firmware of the uio stick but I am unable to do so, a red LED is ON in the UiO stick.

Here is a screenshot of the command prompt when I am trying to update the firmware.

Hi team,

I'm using fx3 to stream video data from fpga to pc using vlc. i have used rgb888 and yuy2 format,  both have worked. as thier guid is mentioend in the descripor files of the example projects. My doubt is as follows , what is the values mentioned in (?), what does it correspond to 

0x59,0x55,0x59,0x32, /* GUID used to identify streaming-encoding format: YUY2 */  --> available from 4cc website
0x00,0x00,0x10,0x00,     -->(?)   what does this mean, 
0x80,0x00,0x00,0xAA,     -->(?)   what does this mean, 
0x00,0x38,0x9B,0x71,   --> (?) what does this mean, 
0x10, /* Number of bits per pixel used to specify color in the decoded video frame.

AND

0x7D, 0xEB, 0x36, 0xE4, /* RGB888 GUID: E436EB7D-524F-11CE-9F53-0020AF0BA770 */ --> available from 4cc website
0x4F, 0x52, 0xCE, 0x11,  -->(?)   what does this mean, 
0x9F, 0x53, 0x00, 0x20, -->(?)   what does this mean, 
0xAF, 0x0B, 0xA7, 0x70,-> (?) what does this mean, 
0x18, /* Number of bits per pixel: 24 */

Also,

i want to stream Y8 and Y16 format   (i.e for y8--->640*480*1 and y16--->640*480*2, no U&V),

i did get the codec for y8 and y16 format from 4cc website,

does cypressfx3 support sending such format, and if yes, can u please tell me what values to include in the (?) regions

0x59,0x31,0x36,0x20, /* Y16 format */  --> available from 4cc website
0x00,0x00,0x00,0x00,     -->(?)   what to add, 
0x00,0x00,0x00,0x00,     -->(?)   what to add, 
0x00,0x00,0x00,0x00,   --> (?) what to add, 
0x10, /* Number of bits per pixel used to specify color in the decoded video frame.

lastly, where can i find MEDIASUBTYPE for diferent guid format.

-Thanks

Hi,

When testing the soft-off strategy of 1EDI3050AS in SIC PM(+18V/-5V), the datasheet shows that the driver IC controls VTOFF when triggering soft-off as shown in the figure below.

But the actual short circuit test waveform is shown in the figure below.The VTOFF will drop quickly to negative voltage first and then rise to the set VPLT level. This causes the power module to turn on twice, which is also not in accordance with the expected soft-off method.
Could you please kindly tell me the reason?

The register parameter VPLT4=8V, tTLTOffPLT=1000ns, tPLTRAMP=500ns.

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 ?
