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 April 11, 2013 at 23:50Hi,I am working on STM10C eval board. I am trying to read X and Y datas from the touchscreen using a state machine inside the I2C_IRQ_Handler. The start byte is generated inside the EXTI interrupt once a touch is det...
Posted on June 17, 2014 at 23:59The PC is always pointing to 0x08000188 (after the .intvec allotment ) So as a workaround I put a B <label> there. The label value is incorrect. This is not using the flash loader. If I use it it fails citing writes t...
Posted on June 23, 2014 at 10:13A GSM modem is in proximity to the uC. When the current bursts of the modem occur I get false logical 1 on my port pins. They are configured as analog inputs. I am using the STM32L100-DISCO board. I was wondering if t...
Posted on June 23, 2014 at 21:14I'm using the SMT32F030 with 48MHz internal clock. I've configured the RTC and noticed it is about 8% fast. Is there a way to make this more accurate through calibration of some sort? Will that have to be done from pa...
Posted on June 23, 2014 at 12:08I use stm32f4 discovery.how can I send a value of a variable to a personal computer?exist an example?
Posted on June 23, 2014 at 14:34 STM32Cube ld scripts set _estack to the last location of RAM like this: /* Highest address of the user mode stack */ _estack = 0x20017FFF; /* end of RAM */ I had several problems with code that u...
Posted on June 20, 2014 at 15:26 Hi, as a beginner I am starting freshly with stm32 programming on a stm32f429-disco board using eclipse with the gnu-arm-plugin and the gnu-arm-eabi toolchain in linux (toolchain is working - the simple LED-b...
Posted on June 19, 2014 at 21:42Hello, I am interfacing an STM32F407 (on DISCOVERY eval) to several devices using SPI bus. One of the devices clocks 4 bytes of data out simultaneously as 4 bytes of config data is clocked in (LTC2446 ADC). I am att...
Posted on May 06, 2014 at 12:11Hi community, I use the USART1 in STM32F100C4 to receive serial data in DMA mode. Because the data comes in packets with less than 16 bytes I start the DMA mode every time, when new data is expected. This works most of...
Posted on June 20, 2014 at 12:18Hi, I'm working on a STM32F4 mcu and I'd like to use an UART with a baud rate of 1843200bps with a DMA that works for every byte received on this UART. Using CubeMX I have created an example code with a UART 1843200b...
