你好,
我用CY8CMBR2016控制器做了一个项目,我遵循了数据表的建议,这个按钮有8毫米直径,更长的轨迹有85毫米,CPIN有2.2nF,计算的寄生电容较大,有17pF,560R的SRIE电阻器,OutsSEL的电阻器。选择带有电阻1K5的编码4位,电阻为1K5的ARST,2.2nF的CMOD Cap,用电阻1K5和敏感电阻1K5进行介质扫描,用5K6的电阻器和3V3的电源进行调试,有的时候PCB单独在引脚上单独进行,没有人触摸,有的人有知道发生了什么事。在引脚4位没有信号。 我的覆盖有2mm,但直到0毫米才起作用,直到2毫米。 OPS在PCB上的其他芯片是NFC控制器,但禁用! 谢谢 最好的问候 以上来自于百度翻译 以下为原文 Hi, I making a project with the CY8CMBR2016 controller, I followed the recommendations of datasheet, the button have 8 mm diameter and the more long trace have 85 mm, the Cpin with 2.2nF, the calculate parasite capacitance the bigger have 17pF, the serie resistor with 560R, the resistor for Out_Sel for select encoding 4-bit with resistor 1K5, ARST with resistor 1K5, CMOD Cap with 2.2nF, Scan with resistor 1K5 and Sensitivity resistor 1k5 for medium, in debug with resistor of 5K6 and power supply with 3V3, some time the PCB alone the pin INT going up alone without anybody touch, Some people have some idea what happened. On the pin 4-bit don't have signal. My overlay have 2mm but doesn't works of 0 until 2 mm OBS the other chip on the PCB are the NFC controller but are disable! Thanks Best Regards |

嗨,克里伯,
去年我和卡普森一起工作的时候也遇到过类似的问题。记住,CMOD电容和串联电阻值需要进行故障排除。 我不记得我用过的确切值,但潜在的事实是,当你增加串联电阻(在你的情况下为5.4 K)时,更多的下降将越过电阻,导致配置超灵敏(不稳定)。我认为560E是理想的值,你可以改变它的调谐,但它不应该超过1K。 试着降低抵抗的价值。如果这使它变得不那么敏感或者如果你没有得到适当的结果,你可以尝试增加。 唱C.MOD值ARNOD 4.7NF(但这会增加感测时间) 如果你想使用的配置细节请让我知道我会从我的档案。 --- Sourabh。 以上来自于百度翻译 以下为原文 hi cleber, i too faced similar issue while working with cap_sence last year. all remembered is that Cmod capacitance and resistance value in series wih need to be troubleshooting. i din't remembered exact values i have used but but the underlying fact is that when you increse the series resistance (5.4 k in your case) more drop will be across the resistance leading the config hyper-sensitive (unstable). i think 560E is ideal value you may vary it for tuning but it should not be in more than 1K . try reducing the value of resistance. if this is making the it less sensitive or if you are not getting proper results you may try incread sing the C_mod value arond 4.7nf (but this will increase the sensing time) if you want details about the configuration used please let me know i will get that from my archives. ---Sourabh. |

你好,
今天,我得到了CXPIN电容器,然后得到的工作(我起飞2.2NF从C.PIN WIKE在数据表中谈论是强制性的工作,但与CXPIN不工作),INT PIN变高,当我触摸一个按钮,有很好的灵敏度,但我没有任何信息在编码4位在任何引脚当我触摸任何按钮时,引脚仍然在GND中,用于选择输出的电阻器是1K5 5%,用于编码4位。 有没有其他人为选择输出?输出引脚是开漏吗? 有很多修改和其他白纸过时。 在BCP工具中是不起作用的。我尝试设置命令行,但是在图表中,没有波形就什么也看不到。 谢谢 以上来自于百度翻译 以下为原文 Hi, Today I got change the C_pin capacitor then is get work ( I take off the 2.2nF from C_pin wich in Datasheet talk about is mandatory for work, but with C_pin does not work), the INT pin going high when I touch a button, have good sensivity, but I dont have any information in encoded 4 bit in any pin, the pin still in GND when I touch any button, the resistor for select output are 1K5 5% for encoded 4 bits. Have some others thinks for select output? Thats pins for output is a Open Drain? Have a lots of revision and others white paper obsolete. In BCP tools was don't work. I try the put command line but in the chart don't see nothing without waveform. Thanks |

你好,
谢谢大家 在为Cmod计算电容器后,为输出选择正确的电阻器,是非常好的工作。多图表工具运行良好,每个按钮工作非常精细。是用于控制器触摸电容的鲁棒芯片。 谢谢 以上来自于百度翻译 以下为原文 Hi, Thanks, for all After wich calculated the capacitor for Cmod and put correct resistor for select output, is are works really fine ever. The multi Chart tools works very well, each button works very fine. Are robust chip for controller touch capacitive. Thanks |
