Hi, I am troubleshooting a custom board using USBPD as sink. It only negotiates a PDO on one orientation of the USBC connector.Checked with an oscilloscope and I see waveform going to CC1 on the orientation that works , naturally, and changing orient...
I've setup an STM32F407 as a CDC Host on the HS peripheral with Full Speed (FS) comms, but the IN transaction always returns a NAK and no Device data is received on the Bulk Data pipe. I used the USB Host example from ST.com (userfunction that only t...
Hello, I am trying to make FDCAN work but I am not receiving any messages. The TX is working fine but when trying to receive messages the interrupt is not triggered. I am using STM32H7 series with freertos. I have set the filter, started FDCAN, enab...
Hi, We are working on a low power application which uses an emmc memory. Now we have problem when Deinit mmc driver. When mmc is disabled we have a base consumption of XXuA (stop 2 power mode) but when it is needed mmc must be enabled (using Init fun...
I am trying to read ADC value of internal tempreature sensor of my STM32F446 board. The data sheet says that the temp sensor is connected to ADC1_IN18 (page no. 37/198), but there is no such pin in STM32F446xx pin and ball descriptions. Can someone p...
Hi there,I am working on STM32F429BIT6, and I have a SD-Card connected.Now, I want to copy some data between the PC and SD-Card by USB directly.Is there any example or document?Anything is welcome, thank you!
ADC1 and ADC2 run in interleaved dual mode using DMA. Resolution for both ADCs is set to 8-bit. ADC1 is sampling CH1 and CH2 in differential mode. The results that I get from DMA are a bit strange: If my positive input is ~1.65V, if my negative input...
tying to find what frequency the hsi is at startup and normally i search the datasheet for clocks and startup but this returns nothing in the datasheet for the stm32h753bi mcu only thing i see is that it has 4 clocks and it says the hsi is 64mhz is ...
Hi All,I have interfaced Winbond W25Q128 external flash and IS42S32400F-7TL external RAM to STM32H750IBK micro on my custom board. I have found an external loader file (stldr) for my pin configuration from a community member.I can program, read and ...
For my project, I need to use a parallel RGB interface (8 bits) to control a display using Nucleo-F411RE. The PCLK for the RGB interface is required to be a minimum of 1MHz.However, the STM32-F411RE does not have any LTDC peripherals. So I implemente...
