Posted on June 01, 2016 at 16:19 I am working with the STM32F405/STM32F407 microcontrollers.I am trying to understand what's happening inside the microcontroller before main() is called and I would like to get rid of as much as possible to minim...
Posted on May 30, 2016 at 05:42Hello, i am in the path of developing brush-less DC servo system for CNC mill, Because i will use motor encoder, as well as position quadrature encoder, i need ability of hardware tracking step and dir impulses. It wo...
Posted on June 02, 2016 at 00:28Hi,I am trying to get STM32CubeMX + arm-gcc + Nucleo-073RZ to do things. It won't.I can see in my debugger and lst file that08000990 <SystemInit>:SystemInit():/Users/dongfang/workspace-arm/stm32cube-playground/Nucleo0...
Posted on June 01, 2016 at 16:35Hi all. I can't get more far than reset handler. On a first instruction I'm failing into HardFault_Handler. SCB->CFSR says STKERR and IMPRECISERR.I see it only in STM32F100C8T6B. They all have rev. Z. All another chi...
Posted on May 14, 2016 at 11:12 Hi, I'm experiencing a really obscure issue on an STM32F103 using the latest CubeF1 HAL, and I suspect that it's related to the way the WFI instruction is called. My scenario is a little bit complex. My code ...
Posted on June 01, 2016 at 17:01HiI'm trying to communicate with ADC through SPI interface with HAL layer and ended up with issues.At start I configure adc:HAL_SPI_Transmit(&hspi1, &SDATAC, 1, 3); //0x16HAL_GPIO_WritePin(GPIOC, START_Pin, GPIO_PIN_S...
Posted on March 21, 2016 at 07:51Hi, I want to ask you if it is possible using HAL to change usb format audio from 16bit to 24bit and vice versa. Now I can choose in windows between different frequencies of 16bit sampling, but if I change usb descri...
Posted on May 10, 2016 at 12:47 I am having an issue with a slow supply ramp, so I have been trying to set theSTM32F042 to do a software reset if the supply is under say 2.5Volts. I've been playing around with the PVD settings, and interrupts to...
Posted on May 31, 2016 at 16:38The task is to measure three phase power. ADC1 measures voltage, ADC2 measures current. Here is the adc configuration routine:static void ADC_Config(void){ ADC_InitTypeDef ADC_InitStructure; ADC_CommonInitTypeD...
Posted on May 31, 2016 at 08:32 Hi, I'm trying to read register in my accelerometer FXOS8700. I'm using code below on STM32L476: uint8_t FXOS8700_ReadReg(uint8_t reg) { uint8_t value=0; HAL_I2C_Master_Transmit(&hi2c1, FXOS8700CQ_SLA...
