STM32F4 DMA source/dest address alignment requirements

The RM0090 Reference manual (DocID018909 Rev 10) mentions on p310 that :When the data width (programmed in the PSIZEor MSIZE bits in the DMA_SxCR register) is a half-word or a word, respectively, the peripheral or memory address written into the DMA_...

Not being able to enable PWM using the HAL TIM library on stm32f0

Posted on April 13, 2016 at 11:21 The goal is to use the PWM feature of stm32 HAL TIM libraries to light up 4 leds on pins 0, 1, 4 and 5 I have generated the following code using CubeMX: void MX_TIM3_Init( void ) { TIM_ClockConfig...

STM32F030RC - Example code or logic explanation for 2 USART's TX and RX through DMA.

Hi, USART1- RX1 and TX1USART2- RX2 and TX22 BUFFERS - BUF1 & BUF2DMA AccessUSART1 - Peripheral to Mem, USART2 - Mem to Peripheral  RX1 receives data and stores it in BUF1. TX2 waits till BUF1 is full. Once BUF1 is full now RX1 h...

USB HID Device

Hi MembersCan some one, please explain what exactly is stm32 USB HID Device.(specifically mouse)..Does it mean that we read a mouse (buttons and cursor) attached to PC with stm32?

Hi! I wonder if someone knows if I should be able to generate an interrupt at a value of the counter when I am in PWM1-mode? I.e.: TIM_ITConfig(TIM1, TIM_IT_CC1, ENABLE) together with TIM_OCInitStructure.TIM_Pulse = value; If possible, how!? Tomas
