Posted on February 11, 2016 at 10:29Hi, on a STM32F207 I want to use coarse calibration but it seems to have no effect. - I changed PRER to PREDIV_A = 63 and PREDIV_S = 511 and print it out on a UART after reset. I changed to these values to have a ...
Posted on October 14, 2016 at 04:23 Dear All, I am trying to apply TIM14 along with pwm and put them to GPIO. The timer setting driver code is here,( one pulse mode has chosen) /* TIM14 init function */ static void MX_TIM14_Ini...
Posted on October 14, 2016 at 04:09Hello everyone, i'm working on an Audio IN endpoint USB Device (a microphone). The idea is to capture audio data from a codec and send this data to a PC by USB by implementing an isochronous IN endpoint.I want to ...
Posted on October 13, 2016 at 06:57Dear All,I am working in STM32F070R8T6.For the Timer base pwm generation I need to use TIM6, I have no option for choosing TIM1 and TIM2.I need to activate internal pwm which may cause by pressing GPIO key button. ...
Posted on October 13, 2016 at 21:56I'm curious what the clock rate limits are on the SWD port of the stm32 parts and whether the stlink interfaces can reach these limits. openocd seems to support changes to the interface speed and will reset the f3...
Posted on October 13, 2016 at 13:51 Hi , I'm newbie with stm32f3 and i want to send the accelerometer data to my raspberry pi 2 through USB , please i need some help ?
Posted on October 13, 2016 at 18:40Hi. There is audio feedback when line-in and headphone jack are used simultaneously on STM32F7 Discovery board. This issue seems to have been discussed in other threads but it doesn't seem clear why this happens. C...
Posted on October 13, 2016 at 16:56STM32F429 - LTDC Display Size LimitThe data sheet for the STM32F429 describes the maximum pixel with of the LTDC as 1204 pixels.However,.. other than CubeMX not allowing the value entered for display width, to be >...
Posted on October 12, 2016 at 22:26The diagram of the IWDG (figure 213) has LSI as a 40KHz clock. The description of IWDG and LSI have it as a 32KHz clock.Which is it? 40? 32? Adjustable?Andrei from The Great White North
Posted on October 12, 2016 at 12:45Hello,I am using STM32F030x. I am trying to read the data from the UART using DMA (channel 2 -> Tx and channel 3-> Rx ). I used CubeMx to generate the initial code and configuration. The DMA is configured in NORMAL...
