Posted on December 01, 2015 at 01:07Hi all, I am writing an application using the stm32cubef7 where I need to sample the temperature sensor channel of ADC1. According to the STM32F746 reference manual the temperature sensor is on channel 18 of ADC1,...
Posted on December 01, 2015 at 01:35I have set the data size to 8 bits for SPI on SPI1 using the pins PB3,4,5, PA15. I see 8 bits of data on the MOSI line corresponding to the 8 bits I put into SPI1-DR. But on the rx side I see the 8 rx bits in SPI-...
Posted on November 12, 2014 at 10:33 Hi at all, I'm working on an stm32f4 trying to use the RTC periodic interrupt but it doesn't work; I'm using an RTC with a 768KHz external oscillator and a working frequency of 1Hz. The RTC set-up is quit...
Posted on November 24, 2015 at 11:59Hi thereI need some methodology advice. I devoloped an application FW for F030F6T6 which I'd like to run on a STM32F4 discovery board just for algorythm debug (I have this board on my desk so why not?).I then crea...
Posted on November 28, 2015 at 18:34 Hello everybody, At the moment I'm studying for an exam based on microcontrollers and I have choose the stm32 family, but I need to program this microcontroller in assembly. In the last meeting with...

Posted on November 30, 2015 at 13:53hello I make custom board with sdram and use stm32f756 chip. Then I try to run modyfied my self version of uclinux (and u-boot) - but system hangs. this is callstack that I build with 2 leds (early printk don't wo...
Posted on November 30, 2015 at 14:24I observe ethernet packet lose then transmitting at high rate: while (1) { while (1) { err = low_level_output( &gnetif, p); if ( err != ERR_OK ) continue; else brea...
Posted on November 30, 2015 at 12:57CubeMx generates stm32f0xx_hal_adc_ex.h In that file in the implementation of macro ADC_CHANNEL_INTERNAL_PATH the returned value is either ADC_CCR_TSEN or ADC_CHANNEL_VREFINT. The second is probably wrong and shou...
Posted on November 26, 2015 at 14:58Hello STM32 users,I've received the STM32F401RE board and am trying to run a test program on it. I downloaded uVision5 and the STM32Cube_FW_F4_V1.9.0 and opened the UART project that came with the package. The ''D...
