Posted on June 02, 2014 at 04:16Hello, I'm using STM32F4 discovery to develop usart communication function. The usart parameter is below. /// Set serial port USART_StructInit(&USART_InitStructure); USART_InitStructure.USART_BaudRate = 9600; ...
Posted on May 31, 2014 at 12:45Hey, I am presently transferring an image from a camera (connected through DCMI) to the internal SRAM via the DMA. This way I'm able to get the whole image. However, when I try to write into the external SRAM through t...

Posted on May 31, 2014 at 16:56Hi everyone, I have just opened my STM3221G-Eval and created the default program for it using IAR Workbench for ARM 7.10. I first wanted to know whether why my LCD stays at white. Thanks
Posted on May 30, 2014 at 15:57 Hi, I am facing a problem with the MCU model STM32F105RB. I am using it with the J-link EDU. I use a custom hardware, which works properly with the STM32F205RB model. Now I am trying to use the same c...
Posted on May 30, 2014 at 11:09I compiled the micro STM32F05k4U6 using the IAR Embedded Workbench for ARM 6.40.2 and I get a binary When I tried to program the binary using the STM32 ST-Link Utility the binary gets download but when I power up the b...
Posted on May 28, 2014 at 08:40 Hi, I have been looking around in the forums for a solution for my target mcu, STM32F I want to use the I2C1_SDA/SCL on PA14/PA These pins are used for JTA-DP and SW-DP. I want to disable this and use only the I2C...
Posted on May 30, 2014 at 17:33I am working on STM32F103 with an external flash memory chip via SPI. I use a very simple data format for storing data onto the flash memory, each record is 16 bytes, all records are saved sequentially. The problem is ...
Posted on May 30, 2014 at 09:57Hi, I need your help...I try to use the USART1 of the STM32F107 to send a string (''HELLO WORLD'') but on the hyperterminal, I receive just the first letter (''H''). I cannot found the fault, I use Coocox CoIDE with th...
Posted on May 30, 2014 at 15:15 Hi Is there a way to disable interrupt nesting (preemption) on the STM32F3Discovery? By default, an interrupt seems to preempt a currently executing ISR. But I want the ISRs (especially those of DMA and EXT...
