Posted on March 18, 2014 at 22:45Hello everyone, i have a few general questions about DMA and i will appreciate the help if someone could answer to my questions. I know it is used to transfer data at high speeds between memory and peripherals, or me...
Posted on March 17, 2014 at 18:51Dear All,I have tested the DAC example on the STM32F429 and I have understood the way using / driving the DAC on the STM32F4. I have tried to create my sample code using the STM32F429 Discovery template, but nothing ...
Posted on March 19, 2014 at 16:08Hello, I have a STM32F100RBT6B board, and I should use some sensors LSM303D with I2C. Just a question: wich is the maximum number of sensors that I can use with an I2C interface? #sensor #i2c
Posted on March 17, 2014 at 13:06Hi, I am using STM32F100RBT6B discovery board and I need to use I2C1 bus. I saw on datasheet that gpio PB6 and PB7 should be used for clock and data. I think to use PB8 and PB9 for the alimentation. Is it correct? N...
Posted on March 19, 2014 at 14:08 Hello Forum, I have been trying to compile the wave player example which came with STM32F4 firmware package. However due to various ifdefs in the code I had problems compiling it. There fore I write my ow...
Posted on March 17, 2014 at 16:18Hello everybody! I check the Stm32Cube graphical pin definition. I want to use FSMC bus SRAM1, with 16 bit bus, and 1 address bit. The address pin I want is PE3, but the cube not allowing use this. If i use 1 bit add...
Posted on March 25, 2013 at 12:30Hi,I have a problem with transmitting character through USART3 port in STM32F207.Here there is the USART configuration code:--------------USART_DeInit(USART3);USART_InitStructure.USART_BaudRate = 115200;USART_InitStr...

Posted on September 14, 2012 at 14:29 I'm working on a project on a STM32F4 CPU, generating signals (VGA) with DMA. I have a generic timer on CPU clock (no prescaler) on a STM32 triggering interrupts on overflow, to generate a periodic signal ...
Posted on March 17, 2014 at 16:56I'm having a problem with my usart communication between stm32f4 and hc-05 bluetooth module. I'm trying to configure the AT command of HC-05 using the stm32 board and i'm checking the response using the USB serial mo...
