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...
Posted on May 05, 2014 at 08:19Hello I use the comparator module of a STM32F051. The problem is that I need to change the input pin of the inverting input on the fly. In the datasheet, for COMP1 module, the input pins PA0, PA4 and PA5 are possible s...
Posted on May 21, 2014 at 00:25Hi,I'm using the STM32F4 Discovery board. I have a program that outputs voltages with the onboard DAC and reads voltages with the ADC. For some reason when the DAC is outputs a voltage it lowers the readings of the ADC...

Posted on May 29, 2014 at 12:54 Hello everybody. I have a problem whith USART. I send data to my STM32F4 through USART3, everything works fine. But when I stop to send datas, the USART RX interrupt still receive the last char sent each ti...
Posted on February 14, 2014 at 18:01Hi All,reading the reference manual of the STM32, I have a question related to a transfer peripheral to memory using DMA, direct mode ( no FIFO )In section 9.3.12, Direct Mode paragraph, i found:Direct modeBy defa...
