Hi,

I'm trying to read analog voltage level at pin #24 (P2.4) but I get a wrong value. Here is my code.

gpio_hsiom_set_config(GPIO_PORT_2_PIN_4, HSIOM_MODE_AMUXB, GPIO_DM_HIZ_ANALOG, 0);
CyDelayUs(200);
pd_adc_calibrate(TYPEC_PORT_0_IDX, PD_ADC_ID_1);
uint8_t level = pd_adc_sample(TYPEC_PORT_0_IDX, PD_ADC_ID_1, PD_ADC_INPUT_AMUX_B);
hsiom_set_config(GPIO_PORT_2_PIN_4, HSIOM_MODE_GPIO);

ADC return value from pd_adc_sample() is very low,  only 2-5. Actual voltage on the pin is 1.1V. The return value is 0 if voltage in pin is 0V so there seems to be a connection. 

However if I use HSIOM_MODE_AMUXA & PD_ADC_INPUT_AMUX_A instead I do get the expected value (~85) but then PD immediately raises app events APP_EVT_RP_CHANGE and  APP_EVT_VBUS_OVP_FAULT. I assume this is because port uses AMUXA to sense the VBUS.

How do I read the pin voltage level correctly with MUXB?

开发新人，有个疑问想寻求帮助。

CCG5有typec端口，我们想把port 1的DPLUS和DMINUS这两个USB2的数据通路通过gpio A6 和A7 传输出去。

就是DPLUS和DMINUS这两个引脚接收到的数据实时的发送出去。

请问，这个功能该怎么实现？

我们在开发CCG5的时候遇到一个问题，请求各位帮助。

问题是这样的：

我们的CCG5定义了一个I2C master，需要与外部IC通信。我们不确定I2C读写操作相关代码应该放在哪里执行？

1、我们放在main函数中执行，虽然I2C读写操作成功了。但导致TYPE-C口的PD协商失败了。

2、我们放在app_event_handler的APP_EVT_PD_CONTRACT_NEGOTIATION_COMPLETE事件中执行，I2C读写失败了。

请教个问题，怎么在CCG5中的UART的RX获取外部发来的数据？

我启用了internal interrupt，然后在代码中添加了如下code：

void uart_debug_rx_isr(void){
G20_origin_led_Write(a);
}

UART_DEBUG_Start();
UART_DEBUG_EnableInt();
UART_DEBUG_SetCustomInterruptHandler(uart_debug_rx_isr);

不仅G20_origin_led_Write(a);没有起作用，串口还会crash。

Hi,

We have a project that was created by ModusToolbox and is based on the MCU (CYPM1322-97BZXIT).
This project is already in production.
Now, we want to have hardware changes and transfer this project to another MCU (CYPM1311-48LQXI).
How can we perform this transfer?

Thanks
