VCONN_SUPPORT

[TSaku.2135]

I would like to enable VCONN based on STM32CubeExpansion_USBPD_F0_V2.1.0.

I found CMACRO "_VCONN_SUPPORT", but I encountered complile errors below if I used _VCONN_SUPPORT.

compiling usbpd_dpm_core.c...

../../../../../../Middlewares/ST/STM32_USBPD_Library/Core/src/usbpd_dpm_core.c(191): error: #20: identifier "USBPD_DPM_EvaluateVconnSwap" is undefined

   USBPD_DPM_EvaluateVconnSwap,

../../../../../../Middlewares/ST/STM32_USBPD_Library/Core/src/usbpd_dpm_core.c(192): error: #20: identifier "USBPD_DPM_PE_VconnPwr" is undefined

   USBPD_DPM_PE_VconnPwr,

../../../../../../Middlewares/ST/STM32_USBPD_Library/Core/src/usbpd_dpm_core.c: 0 warnings, 2 errors

I think I should write these functions in my user code, but I would like to see sample code of these functions.

Please advice.

Dear @TSaku.2135​  ;)

We did not deliver VCONN applications on X-CUBE AFE solution. This solution is no more supported for P-NUCLEO-USB001.

In addition to this solution, we have introduced traditional STM32 MCUs with native hardware interface (called UCPD) to support USB-C and Power Delivery Technology.

This solution �?� described below, is available in STM32G0, STM32G4 and STM32L5 product families.

It comes with a complete ecosystem (such as a discovery kit and a debugging tool) that simplifies UCPD configuration and use.

USB PD middleware stack is now part of STM32Cube (so X-CUBE-USB-PD expansion pack is not needed anymore when this solution is selected)

To make this new solution even more attractive a companion Type-C Port Protection (TCPP01-M12) is available to protect the CC lines against ESD and short to VBus.

Further information on that new offer are available here after.

Anyway, you will find in EVAL-G0 demonstrations code ('.\Projects\STM32G081B-EVAL\Demonstrations\DemoUCPD\') the way to manage VCONN in the FW package.

Dear Yohann M,

Thank you for prompt answers.

I am using TCPM/TCPC configuration with ON-FUSB3-STM32 board. Is that possible to enable VCONN ?

Hello

Please find an update of the project in enabling switch '_VCONN_SUPPORT'.

Thanks to this application, you should see communications with cable.

On my EVAL_FUSB307 board, I changed the jumper JP2 to connect VCONN directly to 5.0V.

For your information, on this FW package, cable information will transit to application thanks to callback 'USBPD_DPM_SetDataInfo' with DataID=USBPD_CORE_IDENTITIY_SOP1:

/**
 * @brief DPM callback to allow PE to update information in DPM/PWR_IF.
 * @param PortNum Port number
 * @param DataId Type of data to be updated in DPM based on @ref USBPD_CORE_DataInfoType_TypeDef
 * @param Size Nb of bytes to be updated in DPM
 * @retval None
 */
void USBPD_DPM_SetDataInfo(uint8_t PortNum, USBPD_CORE_DataInfoType_TypeDef DataId, uint32_t *Ptr, uint32_t Size)
{
 uint32_t index;
 
 /* Check type of information targeted by request */
 switch (DataId)
 {
(...)
 case USBPD_CORE_IDENTITIY_SOP1 :
 {
 uint8_t* disco_ident;
 disco_ident = (uint8_t*)&DPM_Ports[PortNum].VDM_DiscoCableIdentify;
 memcpy(disco_ident, (uint8_t*)Ptr, sizeof(USBPD_DiscoveryIdentity_TypeDef));
 break;
 }
