Resolved! How to disable USB Receive (OUT) (response with NACK) for a while ?
I'm implementing USB CDC for my project. In the USB callback function (CDC_Receive_HS), I copy the contents to a user's data array and exit the function. I process the received data in the main function. (not in USB interrupt routine)What I want to d...
HAL_UART_Transmit_DMA does not check if DMA is actually ready?
Hi,I am using STM32Cube_FW_F4_V1.24.2. I noticed that HAL_UART_Transmit_DMA internally only checks the UART state (line 17) but completely ignores the return value of HAL_DMA_Start_IT (line 48). So what will happen if HAL_DMA_Start_IT returns HAL_BU...
CAN and USB (vcomport) together (CAN USB bridge)
Hello ,I need to design CAN and USB bridge .which micro controller should i be using?.and i have tried STM32l4r5zi, STM32F407vet6, STM32f373 but none of this got worked, every time i have to deinit the CAN and run USB. is there any micro controller...
STM32L1 HAL has compatibility problems on I2C API.
Hi.I have found the STM32L1 HAL generated by CubeIDE doesn't have compatibility with the one generated by CubeMX.For example, According to the UM1816 "Description of STM32L1 HAL and low-layer drivers", I2C has API like following :HAL_I2C_Master_Seque...
Resolved! Queries on DFU, Defuse, DFU file Manager & boot loader
1) Issue is we are unable to upgrade new .dfu file in to a target board (which has STM32F767 ) with different target ID & different target name than already programmed in to our target board. (Please check image with red bottom line)We can be able to...
[Solved] Bug: F105RCT6 HAL_TIM_PWM_Start_DMA starts regular PWM instead of DMA PWM
Whan I call HAL_TIM_PWM_Start_DMA on STM32F105RCT6, it behaves as if I called HAL_TIM_PWM_Start. I.e., it starts regular PWM, without DMA, with Pulsewidth value set in CubeMX and staying still all the time. Seems like it doesn't even look into pData ...
USB device double buffering (CDC Class).
Hi,I have some difficulties to configure USB device using OUT EP double buffering (used with CC class).While using simple buffering we get slow transfer rates (1 out o 2 packet NAKed), when I use HAL_PCDEx_PMAConfig(PCD_DBL_BUF), USB transfers hangs....
