The 2 instances where hfdcan->Instance->TXBAR is written in stm32h7xx_hal_fdcan.c (as means of activating a TX reqeust for a given CANFD packet) use a direct value assignment to the register:hfdcan->Instance->TXBAR = BufferIndex;hfdcan->Instance->TXB...
If we want to implement USB to multi-interface at the same timesUSB to UART1~3USB to I2C1~3USB to SPI USB to PWMUSB to SD cardWe use STM32F4 , USB 2.0 have 5 in / 5 out endpointsi think we could use USB mass storage protocol to implement USB to SDbu...
Hi everyone! I need to write a bootloader for STM32F070CB. What I want is to be able to do Device Firmware Update over USB. On the PC side, there will be a software written in QT so the end-user can update device firmware. I haven't written any bootl...
Is there any example walking thru how to convert a .wav file of the audio to play on STM32F429?
Hi there,I currently have a system where I am using a UART Rx/Tx in "interrupt mode". Right now I am receiving packets of indeterminant length so I have a "header" section that contains the size of the "body section".Basically my code bounces back an...
Posted on May 11, 2017 at 12:58Hi,i designed a flight controller board based on STM32F303. i have a weird problem where each time i assembled a complete board, initially there will be no problem and PC will be able to detect and connect with the boa...
Dear all, can i control GPIOs of STM32F030C8 in system memory bootloader? i.e. i need to force a logic low for a specific pin before and while using the boot-loader?
Hi,what happens when the CPU enters the default bootloader?AN2606 lists all peripheral units that are always re-initialized (e.g. UART, SPI, I2C, ..)What happens to the other ports and GPIOs (e.g. Port E/F/G)? Are all GPIOs reset or do they keep thei...
Hello, In my bootloader time base source is Timer 6 and application its SysTick. When I make same time base for both ( i.e. timer 6), my application works fine.Before jumping to main application I am de-installing timer 6 using below function but sti...
Hi, I am writing my bootloader, I changed MSP and reset handler value correctly so code is able to got application mode. In my application I changed VTOR value as below but still my application is getting stuck post sending data to UART.I am using S...
