Posted on September 11, 2012 at 22:33Hi I would like to run a STM32L151 (M3) with low core clock (to reduce current comsumption) and with high peripheral speed (say 16MHz PWM clock). A possible solution (HSI internal clock for ADC is routed to the M...
Posted on September 10, 2012 at 11:52Hi all,Coming from AVR 8 bits architecture, I plan to work (hard) to develop an IMU under STM32F405xx now.I'd like to know if the following architecture is correct. I believe it's possible from my first readings ...
Posted on September 09, 2012 at 16:31 I found the following bug. I have a 16MHz crystal on my board design. I use the STM32F103RB uC with Atollic True Studio Lite 3.2. The stm32f10x.h advises me to set theHSE_VALUE according to my crys...
Posted on September 05, 2012 at 15:58Hello, I just started a new project with the F103RE controller. Opposed to the F103RB I have used before, the ISP bootloader in this chip simply does not work. Though it is obviously running correctly (verified b...
Posted on September 10, 2012 at 12:26A fairly basic thing to do which I am struggling to find any precise examples for.I want to be able to setup a Comms timeout - specifically on an SPI connection whereby if I don't get a response to a command I s...
Posted on May 26, 2012 at 17:08hi all i try to work with usb host hs for msc. but no answer ! my program in this instruction looped : do { status = USBH_MSC_Read10(&USB_OTG_Core, buff, sector, 512*count); USBH_MSC_HandleBOTXfer(&...
Posted on September 10, 2012 at 09:25In my application I set up SysTick with: SysTick_Config(SystemCoreClock / 1000);to generate a 1ms interrupt.I got some weird timing anomalies and eventually used a timer interrupt to generate 1ms interrupts using...
Posted on July 02, 2011 at 20:18Hello.I'm trying to use the internal temperature sensor, but I can't understand the reference manual formula: Temp = ((V25 - Vsense) / Avg_slope) + 25).In the product datasheet, it says V25 is 1.41 V and Avg_slope is...
Posted on September 07, 2012 at 14:29Hi, I would like to know if its posible to restore st-link firmware on the STM32F103C8. I have 2 boards and I tried to program it to play a little with USB. Can I restore it? How? Thanks in advance.
Posted on September 08, 2012 at 14:48Hi guys, I have a board from hardware guys who told me they had tested this board and everything is fine including SPI1. But I cannot let my SPI1 working because status register bit TXE is always 0. From the spec...
