Posted on May 05, 2016 at 23:17Hi,I'm working on a project that uses the STM32 HAL drivers, and in particular the CAN driver in interrupt mode. I understand that the STM32F407xx microcontroller has three CAN transmit mailboxes, allowing users to ''e...
Posted on May 06, 2016 at 00:01Hi, Set up on USART2 on STM32F4 Discovery board. Using PA2, PA3. I'm using Teraterm with a USB to serial adapter at 115200. After configuration, I send a string from the STM32F4 (''Hello\r'') which I see on the termina...
Posted on May 05, 2016 at 21:50 Hello. I try to set up STMPE, using the bus I2C. I need to control a LED, and the high level on GPIO5 pin is for this purpose necessary. I do setup here so: data_i2c[0] = CHIP_ID_REG; ...
Posted on May 05, 2016 at 19:50Hi! I am using example from CubeMX FW L0 version 1.5.0 PWR/STOP MODE with RTC. I have STM32L052K8 revision Y. Current RUN/STOP = 11/6 mA (!). Where is uA??? I do'nt know. In readme file this example for: ''This example...
Posted on May 05, 2016 at 15:46Hello there, I am trying to use some functions from the arm_math.h library. The problem I am getting undefined reference to them. The compiler sees the structs from arm_math.h correctly though. I dont know what is the ...
Posted on May 05, 2016 at 13:21 Could anyone help me with the fat fs and f_unlink function ? I have created a project in STM32CubeMX (version 4.0), then generated C code and MDK-ARM project. The project is in attachment. I ...
Posted on April 10, 2016 at 20:42Run the ''I2C_TwoBoards_ComDMA'' example in Master mode. And do not connect it to a slave board (to simulate NACK). And you will find that you get stuck in the infinity loop inside the I2Cx_DMA_TX_IRQHandler(). When...
Posted on May 04, 2016 at 10:02Hi all. I am trying to reduce power consumption in my device by disabling the GPIOs ports clocks. I did it by writing '0' in the RCC_AHB1ENR register at the required locations. However, It did not work... Then, I did ...
