Posted on January 21, 2013 at 16:21Hi,I have two identical cards with stm32f4 on them. I think one of them has a broken USART1 on it. If i erase flash on both cards, load the same code onto them, the USART1 only works on one of the cards. Everything...
Posted on January 21, 2013 at 11:12Hey Hi, I have been using stm32f103zet6 (144 pin package, Keil compiler and the debugger is stlink ). In my program i use the Jtag pins as Jtag/Port pins (Depending upon the jumper position and a condition in a pro...
Posted on January 20, 2013 at 02:33Hello All, My ideal setup would be to use adc1, read channels 11,12,13 and the temp as half words then store them in a buffer at a certain memory location. I think the way to do this is to enable the ADC and t...
Posted on January 21, 2013 at 22:08hello forum, I have an industial controller board where I need a reset signal for turning off output relays when the STM32F4 is resetted by either by the 100nF cap at the NRST pin when booting or by the watchdog ...
Posted on January 21, 2013 at 19:16I would like to rename (the device name that shows up in Device Manager) a device that uses the STM32 VCP driver. Is it possible to rebuild the driver to customize these details?
Posted on January 04, 2013 at 10:12Hello all, I am using STM32F2.Pll as clock source which uses HSE as PLL clock source. I want to set my System core clock to 24Mhz and i have done. And I read one of the comment in stm32f2xx_rcc.c which says ''Syst...
Posted on January 03, 2013 at 08:49We have an STM32373C-EVAL board and we've been trying out the firmware demo samples. One thing I've noticed is that if I enable the USE_FULL_ASSERT, most samples will crash. (Well, not crash but get caught in the a...
Posted on January 21, 2013 at 11:30Hello, I newly started working with the stm32f0 discovery board on Coocox. I have downloaded the examples from ST but it doesnt compile. It seems that the linker doesnt find the definition of some types, even if I ...

Posted on January 16, 2013 at 10:06Hi, our institute is currently using STM32F103 devices in a distributed control system. However we are evaluating a switch-over to STM32F40x devices for the sake of its FPU and higher clock speed at comparable cur...
