Dear members,This is actually a follow up question to my last one STM32G071 UCPD library bug or my problem, but instead of digging deeper and deeper to an already well answered question, and probably out of topic too, I guess I better start a new one...
Hi,I have implemented a USB-C PD source using STM32CubeMX and the USBPD middleware. When looking at the trace from TRACER_EMB, I can see that the SRC_CAPABILITIES are sent multiple times:When analyzing it with the STM32G071B-Disco as sink, the SRC_CA...
ROM Check on STM32F030I have an STM32F030 where my product has a requirement to do a ROM check before performing any task. How can I do it? Is there any API which returns the result of ROM check done in bootloader? What’s the easiest way of achieving...
Hi,'Audio_playback_and_record default uses INPUT_DEVICE_DIGITAL_MIC as Audio input.I'd like to replace the Audio input by SAI's I2S with an external mic slave device.I add INPUT_DEVICE_AUDIO_I2S as new Audio output. And run the flow as INPUT_DEVICE_A...
I found senduvdm callback in usbpd_vdm_user,c "USBPD_VDM_SendUVDM(uint8_t PortNum, USBPD_UVDMHeader_TypeDef *pUVDM_Header, uint8_t *pNbData, uint32_t *pVDO)"; and just found one interface,USBPD_StatusTypeDef USBPD_PE_UVDM_RequestMessage (uint8_t Por...
I'm trying to import our old code from 7.3 to 8.32.1 and have a problem with classb tests. To see that the problem is not in our code, I have tested the project included in Class B STM32 Self-test library (Projects\STM32L476G_EVAL\EWARM) and it behav...
Hi, i am currently trying to make the ADC driver code for the stm32f3 version of the colorchord https://github.com/cnlohr/colorchord code work on an stm32f4, as my F4 does not have an on board microphone, also, i still want to use direct audio-line-i...
I used the project in B-G474E-DPOW1, named "USB-PD_Consumer_1port" as usb pd sink, everthing is ok. However, I create the project with the params from "USB-PD_Consumer_1port" just without the usart trace, the new project can't run normal, got error i...
From the document, the sink will check:A SINK must present an Rd resistor and detection is done in two steps:1. detect the presence of Rp resistor2. detect a VBUS ON.I tested in stm32g431rb, connect ucpd_cc to a power adapter(source), Source send the...
I use stm32cubemx try to create a usb pd project, but usb pd can't be choosed.stm32g431rbtx.
