Posted on September 04, 2014 at 11:34hi every body.i have a 6 or 7 sensors which all of them are connected my stm32f407 through ADC,Usart and i2c(kind of sensor fusion)i want to show the data of these sensors in pc through usart.i did this , but i j...
Posted on August 01, 2014 at 02:45Can someone confirm if applying ~5.0V to a 5V tolerant pin on an STM32L151 while unpowered (VDD=0.0V) will damage it?The latest datasheets specify the Absolute Maximum Ratings are VDD+4.0V for FT pins, but bench tes...
Posted on June 12, 2014 at 08:33Hi Did anybody try low-power modes on STM32f030 MCU? Specifically Stop mode. I can't get current under 200 uA. Did anybody succeed and get under this? If yes, please share how? I have disabled almost all of controller...
Posted on September 04, 2014 at 14:44Dear Forumers! I've just started to solder in the pcb components into my pcb. I have a MCU as in the title mentioned, and I've faced a problem about the chip placement. In the official drawing the package only co...
Posted on September 04, 2014 at 18:13 I am trying to set up TIM1 on my STM32F407 to act as a PWM input but I'm not having any luck. I have successfully used TIM2 with an identical circuit but when I modify the code to run on TIM1 I never get the...
Posted on May 20, 2014 at 11:52I just want to place a STM32F401 64pin LQFP chip on my PCB, but to my surprise this chip has 2 pin 1 marking dots, on two diagonal corners. If I position the chip such, that I can read the text ''ARM STM32F401...'', th...
Posted on September 03, 2014 at 14:25Hello Dear Community-Members,I am having a problem with the STM32F207VG generated code from STM32CubeMX and the MicroC Pro Software from MircoE.As I am new in this area I would need some help. The generated HAL f...
Posted on August 08, 2014 at 17:21Hello! I'd like to design minimal schematic for STM32F429. I'd like to have all pins connected to goldpins. I want to program through ST-LINK and SWD. Please check my schematic. It's in the attachment. Thanks! #s...
Posted on September 01, 2014 at 06:25Hello, I have a Discovery board and am using the SPI master DMA example and SPI4. I set NSS as SPI_NSS_HARD_OUTPUT. What I get is CLK, and MOSI come out perfectly, but NSS is pinned low. I put a pullup on it, and...
Posted on September 03, 2014 at 17:26I've been trying to run the system bootloader from my application on an STM32F205. I think that should b feasible, but at present the system firmware behaves badly. Probably I'm doing something wrong, but I can...
