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...
Posted on April 16, 2012 at 15:59 I have a number of *.bin binary files that I want to convert to *.dfu files using the DFU file manager. For convenience I'd like to speed it all p a bit but using batch file. Does the DFU File Manager V3.0.0...
Posted on April 13, 2012 at 19:09ATTENTION! The following code do not work for STM32 I2C while looking good:void I2C_Ini(void){ I2C_InitTypeDef I2C_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; // I2C RCC RCC_APB1PeriphClockCmd(RCC_APB1Periph_...
Posted on April 18, 2012 at 05:10Hello I had a hardware design question on the usage of the USB DFU bootloader on the STM32F4 microcontroller. In ST's AN2606 bootloader appnote it says: ''If DFU (USB FS Device) is used to connect to the bootloader: ...
Posted on April 11, 2012 at 18:39I wonder if someone could help me. I recently have developed my own PCB board. I've soldered all the components, and now I want to starting downloading some firmware to the uC (STM32F407ZG - LQFP144pin). For my surpr...
Posted on April 16, 2012 at 09:07In TRM STM32F4 (RM0090) it says in Chapter 4 ''PWR'', 4.1.2 ''Battery...'': Note ''Due to the fact that the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 are restricted: only one...
Posted on April 16, 2012 at 09:05In the STM32F40x datasheet (Jan. 2012), in pinning table 6 PA1 appears doubled and PA13 is missing (it becomes clear in table 7, that PA13 is SWDIO, but anyway this is an annoying error in such an important table of ...
Posted on April 15, 2012 at 16:30Hi all, Do you know if Joseph will provide us a ''definitive guide to cortex M4'' as done for M3 and M0 ?Herzlich, MCU Lüfter
Posted on April 15, 2012 at 14:51I am using the STM32F4 discovery board to generate a PWM signal using TIMER 1, channel 1, and am using GPIO A8 in AF mode. When i run the code there is no pulse generated, but the pin A8 gets pulled up to Vcc. The a...
Posted on April 12, 2012 at 17:18Hi,I have written a Bootloader that looks at the micro sd card and loads firmware.bin file into address 0x00800C000 and jumps program execution to 0x00800C004. I have changed the Flash address in the code that is loa...
Posted on April 10, 2012 at 22:18While it is clear how to configure the ADC sample time, the documentation doesn't provide insight into why one might prefer 239.5 cycles over 13.5 cycles, or the impact of selecting 7.5 cycles (I'm guessing 6 bits of...
