i have a project want to use stm32h750。but flash stm32h750 is small，just 128Kbytes，and my code is as much as 300Kbytes。so i think i have two way ：1�?connect a extern flash by Quad-SPI，burn my program in extern flash，and boot from address—0x90000000。...
I have an STM32L152R8T6-A MCU. A new firmware is downloaded over HTTP (as a .bin file) and is stored in an external flash memory. After that a bootloader copies the new firmware into MCU flash (address 0x8000000) and resets the micro.Everything is OK...
Hello,I am a new STM32 member. In many previous projects from PIC, we often #define GPIOx as a bit. So we can manipulate some operator directly and easily as example below.Example: #define LED_AL1 LATBbits.LATB6 #define LED_AL2 LA...
How do I restart a timer properly?I can set the counter value, but what about the prescalers?
In the STM32F413/423 reference manual ( RM0430 Rev 8), there are two UART8_RX options, but no UART8_TX option. This seems like a typo, since all other UART instances have both a TX and RX mapping.Also, CubeMX lets you assign UART8_TX to stream 0.
Hello,I want to receive a message from slave-device with my STM32H7 based master-board. Transmitting works fine but the receive (IT as well as blocking) is generating a write message (as it should be when transmitting).I verified this with my Rigol o...
Need open source PTPv2 client (something like ptp4l) for STM32F7. Did somebody encounter something similar for STM32F7? I have been searching but no luck... Need to imlement PTPv2 on STM32 microcontroller ASAP. Please, help...
Posted on August 30, 2017 at 02:52So I'm currently working on a custom HID with STM32L073CZ using code generated by the latest version of Cube and CubeMX, and I'm running into an issue with intermittent enumeration being caused by SETUP packets not ...
