Posted on August 31, 2012 at 01:02I'm trying to use RMII between an STM32F407VE and an SMSC LAN8720 PHY. So far I've followed along with the STM32F4 Ethernet example but am having less than stellar success.As far as I can tell, MDC and MDIO go low a...
Posted on July 23, 2012 at 22:26 hello, i am trying to make interrupt based touchscreen program, but have no luck connecting GPIOB_pin12 to interrupt line i was able to do so in GPIOA_pin1, but still cant figureout how to do that on GPIO...
Posted on July 15, 2013 at 18:50Hi , I am working on Cortex M4F CPU , its 168 MHZ , i know that Cortex M4F is 1.25 MIPS per MHZ so a quick calculation will give me total of 210 MIPS . Lets say i have an algorithm that runs 3 seconds , so what shou...
Posted on July 08, 2013 at 00:37Hello Forum, i am trying to get an overview of the various timer periphals present in the STM32 Mikrocontroller Family. It now seems that the two documents http://www.st.com/st-web-ui/static/active/cn/resource/technic...
Posted on July 17, 2013 at 08:59Hello,I'm trying to make a communication protocol via the UART. I have a M4 and an A8 which communicates via RS485 transmitters.For the trials, the UART is set to 9600 bps, 8 bits per character with one stop bit and a...
Posted on July 18, 2013 at 09:57I am using the STM32L151RBH6 which I believe is a medium density device, I am trying to get SPI working using the STM32Lxx_spi.c library but from reading the header at the top of V1.1.1 the I2S feature is not working ...
Posted on July 04, 2013 at 14:53Hi everybody, I'm trying to make the IAP exampe code from ST running on the Olimex board E-407 (STM32F4) but when i want to erase the flash, a hardfault occurs. More precisely, it happens right after setting the STRT ...
Posted on July 16, 2013 at 17:48Hello,I would like to put a binary file on my STM32F4 : project.bin wich comes with the http://www.ucapps.de/mios32_download.html application. Is there a way to do this with atollic true studio, or do I have to use so...
Posted on July 17, 2013 at 11:35 Hi, I have a problem with my CAN configuration, I try to interface the STM32 with a NI USB/CAN. The problem is the baudrate configuration I think, see my code below : GPIO_InitTypeDef GPIO_...
Posted on July 10, 2013 at 11:46I have some problems with DCMI (stm32f407vgt6 mcu).I saw on forums the examples of reading data from camera and sending it through DMA to LCD.What I want is to get the data from DCMI, save 1 frame to internal SRAM mem...
