Posted on January 21, 2014 at 18:00Hello,We are developping an application on STM32F401CC mcu and we are not sure that our clock configuration is correct because, when we are setting baud rate of USART1 or USART2 greater than 115200 bps, data exchan...
Posted on January 20, 2014 at 19:43 Hi Everybody, i'm trying to get some of the STM32F0 peripherals (in this case GPIO, SysTick, NVIC, SPI, DMA) working. Im using IAR EW 6.7 + IAR I-Jet (which is connected via SWD to the Chip). A...
Posted on October 17, 2012 at 16:58Hi,I have a problem while developing a USB-to-serial device and I am looking for a solution.I successfully implemented a USB virtual COM port on STM32F407 microcontroller. I can send and receive data to/from the co...
Posted on January 21, 2014 at 13:46Hello I am using STM32f103RET6 in my project. This project is very important and device should never stop working. Also device is remote and it is not possible to reset it easily. I try to use WWDG for unforesee...
Posted on January 20, 2014 at 11:43Hi,I have a problem with the STM32F3Discovery because i want to capture the signal of the board to watch and display it on my PC. I am using ''Keil'' programm, but i'm not able to do it. Is there someone who could ...
Posted on January 21, 2014 at 04:13Hi, this is my first post and first time working on an stm, so I am a bit new to this. I have a circuit I have been working on as a hobby. When the circuit is receiving, it is getting data from a device, and when i...
Posted on January 03, 2014 at 06:45 Hi, I am attempting to use timer 8 to trigger adc sampling using stm32f1. I have referred to some example on the forum from Clive1 which is using timer 1 . However the code does not work when i c...
Posted on January 21, 2014 at 07:45Hello, I use stm32f415 and have bus fault with random adress. For example the content of BFAR register is 0x268dfb8; 0Ñ…4B404288; today i have 0xE000ED38. And frequency of bus fault change when I change the priorit...
Posted on January 18, 2014 at 08:29Hi all, recently I layout a pcb with stm32w108cu64(copy from the MB954 Zigbee Domoboard)But it seems doesn't work. I try to use ST flash loader to connect the board, but fail. The I measure the VREG_OUT is 1.786V a...
Posted on January 20, 2014 at 16:44I'm on an STM32 F2, but a generic idea would be ideal :) Is there any way to get a high level 'reasonably' accurate idea of how busy the cpu? Given the variety of peripherals and so on I'm sure its quite a challeng...
