STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on February 05, 2014 at 16:08Hi Support, As to date, I have successfully implement smart card TX and RX together with DMA. But I encounter a problem. It is regarding on guard time. As per Reference Manual, the guard time can be configured, bu...
Posted on November 18, 2013 at 18:22I am a beginner with STM32F4 and I am study the ETH driver procedure but I don't understand some instructions For example: /* Clear MBC bits in the selected MAC address high register */ (*(__IO uint32_t *) (E...
Posted on February 05, 2014 at 13:44I have an array of data being played out of a DAC using DMA transfer, with the trigger provided by a timer (TIM6). This works fine, but I would like to occasionally change the data at run time. To do this I have c...
Posted on February 05, 2014 at 13:41Hi,Kit using : STM32Discovery Board(STM32F100 controller)I have implemented the input capture mechanism for Timer15 channel 1. In which I set triggering for both falling and rising edge.Now I am trying to port the...
Posted on February 04, 2014 at 22:23Hello, I have problem with software implementation of SVPWM Space Vector PWM modulation for STM32F1 microcontroler. My application is scalar V/F converter for 3 phase asynchronous motor. Does anyone have such read...
Posted on February 04, 2014 at 13:38I had connected 0.1uF to reset pin which was creating problem while debugging with ulink2 on keil. This was given in datasheet.But on removing this capacitor from reset pin , debugger works fine & running. But whe...
Posted on February 04, 2014 at 12:45Hi,I want to calculate CRC with hardware CRC but polynomial on the register is work on 32 bits.Can possible to calculate CRC 8-bits with hardware in the MCU? And how?Or I have to use sw crc.Thank everyone.
Posted on February 04, 2014 at 15:28Hi there,In my application I need precise control of applied voltage. I use 12bit DAC with 2.5V reference. The mcu is stm32f107I was going to do error budget analysis but was confused by the datasheet. It gives +/...
Posted on January 15, 2014 at 17:26Hi I am writing an I2C interrupt handler for the STM32F207 and am using the Standard Peripheral Library. The problem I currently have is how to set up a NAK when receiving 1 byte from an I2C slave. According to the...
Posted on February 04, 2014 at 16:14I am attempting to get the CPAL I2C library to work with an STM32F407. In the DMA TC ISR handler, the code checks for the BTF flag to be set before sending the stop condition. The problem is that the BTF flag neve...
