Posted on April 28, 2016 at 16:45I have a stm32f4-discovery with the stm32f407vg uC on it and I'm trying to program the ADC1 and measure some signals on the port PC7 with it. According to the documentation PC7 hangs on the ADC12_IN15 which I'm inter...
Posted on April 28, 2016 at 15:16Hi, we are surveying microcontrollers for a new product where we need at least 2 SPI interfaces and 2 uart interfaces. All of these 4 interfaces will have to be able to operate concurrently.I have some trouble unders...
Posted on April 29, 2016 at 01:24STM32 programming interface doubtsHello all.I'm new to ST microcontrollers (STM32 in this case) and JTAG interface. I'm doing the schematic of a project where one of these microcontrollers will be used:- STM32F401RCT...
Posted on April 29, 2016 at 12:19 Hello I have question about i2c. My mcu i2c pin connect to i2c pin evaluation board BU945 My i2c init like this I2C1Handle.Instance = I2C1; I2C1Handle.Init.AddressingMode = I2C_ADDRESSINGMODE_7B...
Posted on April 19, 2016 at 15:18Hi, I´m using TIM3(output compare mode) in stm32f072 to generate waveform via GPIO. My function principle is: - timer initializing - timer is still running, only is enabled TIM_IT_CC3 a output TIM_CCER_CC3E (BUS_Set_...
Posted on April 28, 2016 at 07:11Hi, I have made a custom bootloader, but it sometimes freeze when going from bootloader to the actual firmware. Usually the bootloader should just go to the firmware by doing the following:uint32_t startAddress = *(...

Posted on April 29, 2016 at 07:22Hello, I have discovery board , which runs with stm32f407vg MCU. i want to measure the system core clock by bringing it on the gpio or any other means ??Is it doable ? please help me how to do it #clock #stm32
Posted on April 24, 2016 at 06:25Simple question If I set some interrupts priorities to 0, should I expect time measurements (down to the microsecond) to be inaccurate? ( using SystemCoreClock and SysTick->VAL )
Posted on March 28, 2016 at 18:59Hi,I would like to share an idea here about a way to auto-test our boards (based on STM32F215 LQFP64) to prevents shorts in both contexts:1. after reflow process as partial QC,2. during the product life: after each s...
