Posted on June 24, 2013 at 15:13 Hi All , Till now i worked with the STM3240G-EVAL , At the beginning i had a problem that i received DMA timeout when i tried to write to the sd-card. The was due to a problem that the DMA interrupt ,...
Posted on June 29, 2013 at 14:22 Hi there, I got stuck on communicating with a PCF.. I know that i have the address right, because i connected the chip to my Arduino for testing. The program gets stuck onwhile(!I2C_CheckEven...
Posted on June 28, 2013 at 21:47Hi all, please could you help me to identify changes in communication using serial port and STM32 bootloader, i'm able to program STM32F103 with version 2.2 chip ID 414 but i can't program STM32F407 with bootloader ve...
Posted on June 27, 2013 at 20:47Hi. I used one of the examples shipped with Discovery as a template for my code. Basically, a GPIO input (PA0) is coupled to a function generator and every time an interrupt is detected, a different pin goes HI/LO to...
Posted on March 11, 2013 at 15:53I loaded data into ROM page 11. I then changed from 1’s to 0’s from my running code. So far so good.Now I want to prevent my code from being read via a debugger.I can set FLASH_OPTCR bits 8..15 to 0xBB in my co...
Posted on May 26, 2013 at 01:24I want to use a Light Dependent Resistor (LDR) to control a door ( open when it feel light and close it when it's darkness).Can you help me how can I do this,.Thanks a lot #basic-electronics #getting-start #cross-po...

Posted on June 28, 2013 at 10:10MCU: STM32 F207 VG We try to upgrade a device from STM32 F107 to F207. We are glad to use the ''old'' RTC and to have a simple 32bit counter with a free settable prescaler (our RTC works at 1024Hz). Now the ''new'' RT...
Posted on June 28, 2013 at 11:12Hi Everyone! Sorry for interrupting all of you, but I have a problem. Next year I will graduate from my University as an Electrical Engineer (at least on paper I will be one). For my thesis I'm currently using an STM3...
Posted on January 24, 2013 at 13:39Hi,I'm trying to make STM32F3 device wake up from sleep using LSI. According to datasheet it should not require LSE for such operation. I do get no wakeup interrupt if I don't connect 32khz external crystall or dis...
