I'm trying to make a vcp implementation with STM32f407 and freertos.I have no problem sending data from STM to my pc.When I send data from PC to STM, when I send a few tens of bytes of data, the CDC_Receive_FS function is triggered several times and ...
I am trying to setup USB communication with an STM32F446REIt is a custom board where:The clock source is an external 8Mhz quartzThere is a micro USB port with USB+ connected to PA12 and USB- connected to PA11The external quartz is working (I can load...
I want to use STM32F413 for my PCB design. I need USB data lines for communicating with a computer. Ideally, I would not have any oscillator on the PCB to save space. I noticed that's it's not possible to use HSI for the USB clock on CubeMX. Can I us...
I use MDK 5.32. In the debug interface - Peripherals - System Viewer - COMP window, the value of CSR is always 0 after initialization and the address of CSR is viewed as 0x40007C1C. But CSR's address is 0x4001001C in STM32F37xc.h. What's the mat...
I am trying to set the FIFO sizes for an application that uses 6 bulk IN endpoints. When I write to OTG_HS_DIEPTXF1, it appears that OTG_HS_DIEPTXF5 takes on the same value. Same for DIEPTXF6 taking on the value of DIEPTXF2, and for DIEPTXF7 taking o...
I'm trying realize with IEC61850 . I try to do GOOSE Publisher device. As I understood, GOOSE message goes to NET without any headers. I use lwip library. I found there IP_Forward functions, wich help send dirrectly my message to NET. But it also add...
Hi there,I'm trying to jump from my application to the bootloader on a STM32F103.The bootloader address is 0x1FFFF000This is my code, but unfortunately, it doesn't work:void (*f_boot_jump)();f_boot_jump = (void (*)(void)) (*((uint32_t *)(0x1FFFF000 +...
I have a problem using CAN on STM32F103C8T6. I use this MCU on a bluepill board,a SN64HVD230 based CAN PHY and on the other end of the CAN bus a PiCAN2 board onRaspberry Pi. I drew a picture to show my setup:I want to have a 500 kbit/s-CAN-connection...
Dear All.Based on HAL library, I make small project where I have USB HS with external PHY (USB3300) and CDC class. Works well. What I need is to implement Vbus sensing. This can be done only via external phy, there are some flags in registers to enab...
I want to let STM32L010K4T can jump from my application into bootloader of system memory. (Without hardware pin to set BOOT0 to 1)According to document AN2606 page 237:Note: Due to empty check mechanism present on this product, it is not possible to ...
