Posted on February 13, 2017 at 07:53Hibefore I start my ethernet project, i would like to know the theoretical limits of ethrenet on STM32F407Z. What is the computational load on the ARM when running Freertos + LWIP + 100 mbs .AN3102 only mentions S...
Posted on February 10, 2017 at 20:30Datasheet does not explain the settings corresponding to boot0 pin high or low - could I please get some information on this for the csp-49 package which only has boot0 and no other boot configuration pins. #stm32...
Posted on February 10, 2017 at 07:20Hello, I'm trying to write an I2C slave using HAL which can accept variable length packet sizes. I know this question has been asked before but haven't seen any solutions yet! The master can send data packets of ...
Posted on February 07, 2017 at 10:44Hello,we are developed products based on STM F0 (F072RB) and F4 (F405VG) Series. We use the DFUSe Bootloader to program our devices using USB. Every thing works as expected, great job and thanks to ST for this sol...
Posted on January 16, 2017 at 04:37 Edit: Seems as if this wasn't a permanent fix. It still happens ... but why? I then always have to step through the HAL_Init & sysclockcfg functions until the timer is started. Only then can I resume the ...
Posted on January 26, 2017 at 15:09Hello,I'm using a STM32F767BI and I want to use the bootloader functonnality. I want to use USART1 (PA9/PA10) and the BOOT0 pin. I read AN2606 and I use pattern 9 (nDBANK(bit) = 1, Boot(pin) = 1 and BOOT_ADD1(opti...
Posted on February 05, 2017 at 14:27Hi.I am working on STM32F072RB MCU. I can able to Program and Erase the Flash Page. But, I have few doubt about Flash programming. Sometimes the Data is not written in Flash, when i erase a same and write again it...
Posted on February 04, 2017 at 04:11I am using CubeMX with the STM32L4 1.5.2 library. [EDIT -- just confirmed that this exists in 1.6.0 as well]The non-OTG implementation of HAL_PCDEx_BCD_VBUSDetect() will only call HAL_PCDEx_BCD_Callback() with PC...
Posted on February 03, 2017 at 17:57I'm trying to implement an XMODEM file transfer through the USB CDC Interface on an STM32L4 processor in Full-Speed and seem to be having issues with XMODEM 132 byte packets getting split up and one of the middle ...
Posted on January 30, 2017 at 17:36Hi,I am using stm32f429 mcu and i can use usb communication with my board. I want to learn how to download my hex file to mcu from usb port of the mcu. In other words i want to use a simple gui software on my compu...
