Hello,I'm designing an application where a PCB with STM32F031C6 has to receive a minimum of 5 bytes via an half-duplex communication. Transmission is delimited by special character, ASCII is used. Ideally, the transmission would be composed by 3 data...
Hello everyoneI use STM32F429ZIT6 to make USB mass storage.Download DATA from NADN FLASH to the USB flash drive.I am currently experiencing a problem. When I am still transferring, I unplug the USB flash drive.The MCU only has TIME execution, the ma...
I'm having trouble understanding correct usage of the HAL UART functions to receive incoming bytes. The function assumes you know the byte count in advance. I would expect a receive function to respond to receive buffer full,empty and maybe half full...
Hi,I'm working with a STM32F446, on a CAN Bus system. My question is on PDF documents: there is a new version of the document UM1725 (or other) where find the new complete set of functions (like HAL_CAN_AddTxMessage(..)) ? . The only way is read the ...
Hi, in case someone else have the same issue which is Installed the WIN7 64Bits USB Virtual COM Port cant't start with Code 10, Software and Library versions, I am using Firmware Library "STM32Cube_FW_F4_V1.24.0"STM32CubeMX V5.0.1 and STM32Cube V1....
I’m trying to use the iap sample for the L091 in the cube f0 1.9.x version. It looks like whenever the iap returns from ymodem up or download the uart does not work anymore?
I have 4 channels in my code. For testing, I want to start with 2. The callback is functioning. When the callback executes, how do I know which channel is being returned on the callback? Unable to find any posts on this, and ST has no examples using...
Hello togetherI'm brand new to the field and I'm just starting getting used to it. So please forgive me "stupid questions" :)The ultimate goal of my task is to continuously analyze sensor data by means of an STM32 (currently F44RE Nucleo board for te...
I'm trying to migrate my project from HAL to LL. I use USART+DMA. Reception is OK, but transmission is not.There's a uint8_t transmission buffer. E.g. it begins with {1, 2, 3, 4}.When I set DMA data length to 1, nothing is sentWhen I set data length ...
Posted on October 04, 2017 at 15:39Hi all,I've been working with the STM32F767ZIT6 rev. 'Z' and this went pretty well up to the point where I needed to add an Ethernet connection. My project is running fine with FreeRTOS, UART2, UART3, some Input an...
