Posted on March 20, 2017 at 13:57Hi all,I am not able to get SPI working on stm32l151rbt6a. I have posted my initialization code below./* SPI1 init function */void MX_SPI1_Init(void){ GPIO_InitTypeDef GPIO_InitStruct; SPI_HandleTypeDef hspi1...
Posted on May 15, 2017 at 10:43Hello dear forum,I am using F103RC to drive 2 DC motorsThats why I need to use both TIM1 and TIM8However TIM1_CH2 is at the same pin as the USART1_TXI dont use and init USART1_TX pin becouse I only use RX input of USAR...
Posted on May 03, 2017 at 23:26Hi all,I have 3 boards with 3 different MCUs, one with STM32L053R8T6, one with STM32L152RCT6, and one with STM32L443RCT6.All use same 32,768Khz LSE crystal and 12pF caps. But only STM32L053 works fine when LSE is turne...
Posted on April 28, 2017 at 11:37Hi,Currently, I'm working on a project where LCD, Camera and CAN are involved.I'm using STM32F769I-EVAL platform for my work with 'SetupSTM32CubeMX-4.19.0' installation and 'STM32Cube_FW_F7_V1.6.0' firmware package.A...

Posted on May 13, 2017 at 14:48 Hi In the USART chapter of The STM32F7 ref. manual wrote that USART peripheral can reach up to 27Mbps buad rate. so I have some questions about that. First, just the STM32F7's USART can reach to this maximum spee...

Posted on May 11, 2017 at 04:59Hi,Is there any way to prevent some interrupt sources waking up when in stop mode except the one I want? I may not know what interrupts are enabled/disabled when entering stop mode (obviously I could check the registe...
Posted on May 14, 2017 at 11:51I am planning to use , stm32 for usb emulation. I just want to create emulation of thermal printer using stm32, in which whenever i connect stm32 in to Window PC , it should detect as thermal printer is connected to wi...
Posted on May 14, 2017 at 11:46I am coding for quadrature encoder interface with STM32F301. I have two questions. 1. Do you have a complete code with STM32CubeMX to initialize TIM2 to interface with the encoder for reference? 2. I used STM32CubeMX t...
