Im using a STM32L152RDT6 in my design and a regulator TPS78326 which does the power supply to the STM. If waking up from STANDBY, the load transient response causes a drop of Vin. In this case 2.6V to 2.4V. The STM is supposed to work down to 1.8V, s...
I am doing a project using STM32H753 controller. When I flash USB HS MSC example code and transfer files , speed is very slow. It seems no difference between FS and HS modes. A large compressed files do not get transferred. Please help.
I am having problem with writing program to internal flash memory. How to read from flash and write to flash? How to compare flash contents with uint8_t array contents? How to write uint8_t array contents to flash memory ? Please help
Solved: The problem was an improper reading, the BKSRAM-clock was not initialized when reading back the report. Updating with "correct" code for posterity.I'm writing a (better) hard-fault handler for my STM32f207zg and want to do the following:Have ...
We are bringing up a new board and having troubles establishing SWD connection, I was reaching out seeking help with this.Target - STM32F091RCICSP - ST-Link/V2IDE - TrueSTUDIOThis is our first use of the ST-Link outside of Nucleo-64 board development...
Posted on June 13, 2018 at 11:39If i understand correctly, it is only possible to drive a step motor for a certain time, but what i need is to drive a specified number of steps. In extreme case one step and in best case without jitter.I can get out ...
I am going to use STM32F030k6t6. IC is not having VBAT pin. Please suggest how to make RTC active when power is off
I have a microcontroller that restarts by switching a switch to PE1 (Pin 142).The switch is grounded and has a resistance to VCC. PE1 is connected between resistor and switch via a low-pass filter.I'm worried that VDD (pin 144) has a cold solder join...
Hello,I have an application, where I need ADC samples at a fixed rate, if the device is running. So, I can do a ADC self-calibration at start up and while idle, but not while the application is running.The application can run for several hours and th...
On an STM32F103 I configure SPI in 16bit wide mode and set up a DMA transfer to transmit one word:SPI2->CR1 &= ~SPI_CR1_SPE; SPI2->CR2 = 0; SPI2->CR1 = SPI_CR1_SSM | SPI_CR1_SSI | SPI_CR1_DFF | SPI_CR1_SPE | /* Some baud rate flag...
