CubeMX provides a library for using CDC but its not very clear and also i couldn't find any good descriptions of functions and what they are supposed to do so can anyone point me to a good tutorial i'll be glad
Hi Everyone, I've been trying to read multiple ADC channels(ADC_CHANNEL_1 and ADC_CHANNEL_0) . Would you please tel me whats wrong with my code. I came to know that I will have to use DMA and the settings seem all alright to me!. Would it be possible to avoid using DMA. I just need to read the channels once in every loop. I checked some the…(Show moreShow less)
How to make on STM32F4 USB a host with support of the Composite device? I made the project in CubeMX, but in this project there is a support of different classes of devices, but there is no support of the Composite device.
Dear Community Members & STM32 funs, BEST WISHES for the New Year!!! Our wish to have a new Community with advances features is already carried out in December 2016. For sure, we still have other wishes Our doors are opened; express yourself, share your expectations, let us and all the STM32 Community hear you: What other features to…(Show moreShow less)
Hey guys, I created 2 sets of projects with CubeMX for my STM32F429I-Disc 1 board. I project is a Device HID project, the other one is a Device Custom HID project. The Device HID projects works fine, the Custom HID project compiles correctly but will not flash onto my MCU. I'm aware that for the custom HID USB routine to actually work,…(Show moreShow less)
If pulling BOOT0 High solves the problem you need to look more critically at what your code is doing with the GPIO pins used for JTAG/SWD connectivity, or going into a low power mode. Check also behaviour with the ST-LINK Utilities
If you mean question on a product, no. Say you have an STM32-related question, then go to STM32 MCUs Forum and ask it there. Forums on other products are listed under "Forums" on the top menu. JWPreviewHide preview
Hi, I've been debugging this for quite a few hours now, wish I had found this thread sooner... Being almost certain that I had done something wrong outside HAL, I've gone through quite a few iterations. In any case, what I have conluded is that there is likely a race condition in the HAL HAL_ETH_TransmitFrame (stm32f7xx_hal_eth.c, version…
I have two boards designed for stm32f405 and stm32f411 to test uSD card. The problem of using uSD on STM32F405 was fixed as discussed earlier: MicroSD card problem, bug in the file(stm32f4xx_hal_sd.c) ? Reading file/writing file are totally fine withut any problem on the STM32F405. Then I study the another board with a chip stm32f411ret6.…(Show moreShow less)
47K pull up is up to me too weak (i had this value on my problematic proto SD board), it was perfectly fin ewith some sd card but not all. it was Pmod SD: Full-sized SD Card Slot - Digilent but likely a rev A i remenber 47K pull up not 10K as in this new revb. some extra input if that can help: Check SD/DMa irq pri same in both project ?…
You want us to use the HAL, ok fine. We use the HAL. But we still often times need to know what hardware we are running on. What is the factory approved method for determining which board/chip is running? Where is the list of HAL Device IDs and what those ID correspond to?
