Hi all,

我通过串口向psoc发一组帧，其中包含0x00，但是使用XX_UartGetChar()函数接收，会默认把0x00舍去。

这个接收函数只能接收1-255，把0当做error。

所以，如果要实现接收含有0x00的一组帧，应该怎么处理这种问题，还是说需要参考XX_UartGetChar()，自己写一个函数？

Hi Sir ,

    In the UART configure Tab , there is a parameter  of oversampling . If I set it 12 , that means ,the 12 sample of level must be the same,and congfirm the final level on

the Pin.Is that right?

    Thanks.

Hello,

It's me again!

I'm using CapSense in a manual mode with all the parameters set (as far as all can be set in the window of the component) but I found out that my raw count dont go back always to the same value as you can see on that simple screen when I put something in the vicinity of the proximity sensor.

The parameters I have set are:

• IDACMOD = 13
• IDACComp = 12
• Modulator clock =1 (12000khz)
• Sensor clock=16 (375kHz)
• Fingerth=48
• Noiseth=24
• Negnoiseth=24
• Hysteresis=6
• Debounce=3
• Lowbaselinereset=30
• Proxtouchtreshold=144
• Snsclksource=64 (PRS8)

I see the sensor frequency that it's the maximum and the average is 187.5khz. Does it mean that it's changing and it could be the reason?

Thank you so much

Hi SIr,

psoc4014系列只有一个TCPWM块，每个tcpwm可以输出两路pwm信号吗，如果可以的话，又有什么注意事项呢

项目需要驱动两个pwm灯，都是按照同一个标准的呼吸灯，只是同时只会存在一个。

4014系列能否满足要求，还是说需要选择TCPWM块数更多的psoc4000s系列呢？

Hi, I'm using a CY8C4245AZI-M443 MCU and I've a problem: I have found the VCCD capacitor irretrievably broken many times on the board. Does this capacitor have a particular quality/dielectric?

Thank you for help.

I'm developing a project for CY8C4A45LQI-483 (PSoC Analog Coprocessor) with PSoC Creator 4.2.

I inserted the components "Switched-Cap. VDAC (13-bit) [v1.40]” and “Scanning SAR ADC [v3.10]” but the notice list shows the following advices:

- Info from component: Scan_ADC. The Scan_ADC_v3_10 component (Scan_ADC) is not compatible with the selected device. Please check the data sheet for details on updating to a compatible component.

- Info from component: VDAC. The UAB_VDAC_v1_40 component (VDAC) is not compatible with the selected device. Please check the data sheet for details on updating to a compatible component.

I also selected the "Update components ..." menu item but the two components appear already updated.

Hi,

   smartIO has 8 LUTs. It can be configured as combinatorial with an output mapping,which is the truth table value.

   Can the output mapping be writed as an expression of input ,like its funtion?

   For example,the following picture,using an expression with right side operators or functions instead of figure 0x7f.

   how to do it?

Hey !

I use Psoc 4.2 BLE with my own service, i try to do an application java to find my chip on bluetooth with bluecove 2.1.1 snapshot but it doesn't work.

Do you have an java app already made ? or can you help me ? it's for me PhD and i doesn't have much time.

My goal is to find automatically me chip, access to my service and read value.

Thanks for the answer
