Hello! I'm using CH310X-EVK and trying to get ECG signal. In the document GH(M)3x2x_EVK_Tool_User_Guide_Rev.2.8.pdf I could not find discription for this page. Could you sent it to me or write in which document I can find it. Thanks a lot.

Hello, the configuration we provided yesterday requires both wearing and lead on detection to trigger ECG sampling. We found that you were able to collect ECG signals on March 15th, but the lead status has always been off. We suggest that based on your configuration from March 15th, you switch the communication method of the EVK board from USB to a Bluetooth dongle. This can help avoid USB common-mode interference. Please see if this change can solve the lead status issue.

Hello!
We tried to apply your ini file, but result is - no signal ECG, Wear and Lead states are OFF. Why so?

Hello, you can verify it directly using the configuration of the attachment

Hello!
I've checked __FUNC_TYPE_ECG_ENABLE__ is set to 1, but I still can't get Lead State is ON and ECG signal with recommended settings.
Have you seen my settings? What should I change to get an ECG signal?

Hello,
you can find the macro definition "__FUNC_TYPE_ECG_ENABLE__" at line 75 in the gh_demo_config.h file in the SDK package. Then, you can use the Keil project "cardiffa-evk\STM32_F412\Projects\STM32F412G-Discovery\CardiffEvkDemo\MDK-ARM_WithDrvSrc\Project.uvprojx" from the SDK package to compile and download it to the EVK board.

Hi,
About Lead Status on EVK, please make sure lead function is opened in configuration and SDK.
For configuration:
1. make sure LEAD_ON adn LEAD_OFF is enable in 'enable_event' part of ‘HOST_INTF’
2. make sure 'DETECT_ENABLE' is enable in 'lead_detect' part of "SAMPLE"
For SDK: make sure __FUNC_TYPE_ECG_ENABLE__ is set to 1 .
The process of ECG sampling typically involves the following steps:
1. load ecg configuraiton and click 'start' to start ecg, Lead State is OFF.
2. When all electrods are applied to skin, Lead State is On and start ECG sampling, and ecg signal is showed on the screen
3. When finger is removed from the electrode, Lead State is OFF and stop ECG sampling.

Thanks a lot for answer. Present time our company is assuming to use your chip in our device. What for was bought EVK. We try to get some ECG signal, and quite successfully do but still have some questions.
When the electrods is applied to skin and we can see ECG signal the Lead State is OFF. We tried some configurations of electrods and Lead State most time is OFF.
