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 20, 2015 at 10:03Hi All,Please see below I2C protocal:I am using STM32F401 Discover Board, the slave is on board CS43L22, the address is 0x94.I try to send 0x01 to register 0x02: Single_WriteI2C(0x02,0x01), but only send out address,...
Posted on April 18, 2015 at 03:00Hi all,I'm coming from the PICmicro world, and thought I'd get into ARM processors, so picked up an STM32L100C-DISCO. I want to understand the basics -- for example, how to create a simple program to blink an LED.I ...
Posted on April 21, 2015 at 00:30 Hi folks, I'm using Bitmap Converter (BmpCvtST.exe, v5.26, STemWin package) to convert images for display. Ordinarily when I save I select the ''High color [565] compressed'' output format and all is well. At...
Posted on April 20, 2015 at 15:50Written this code many times. No clue why it is not working. See any obvious errors?//CODE FOR INIT. Note that APB2 clocks are initialized for ports GPIO_InitTypeDef GPIO_EXTI0; GPIO_EXTI0.GPIO_Pin = GPIO_Pin_7; ...
Posted on April 20, 2015 at 19:36I'm migrating from PIC32s, so bear with me please. I'm trying to get up to speed on the STM32 using the Cube examples in EWARM. I'll try to keep this simple (I apologize, I don't know the syntax for code tags in th...
Posted on April 20, 2015 at 20:36 I am currently have intermittent issue where I am getting stuck in ''void USB_HP_CAN_TX_IRQHandler(void)'', Everything works well from minutes to hours then I notice my CAN traffic stops, currently I TX one mess...
Posted on April 20, 2015 at 19:20 Hello everybody, i m a newbe to stm32 programming i wrote below function for read first 7 pins of GPIOA but its value only return 0x4444444 for GPIOA->CRL , it doesent matter if i change deep config whats wrong ...
Posted on April 20, 2015 at 10:33Hi, i have an external GPS signal that delivers seconds pulses (a short pulse every second). My goal is to count seconds in SW and trigger some actions every X seconds. Question a) I intend to use EXTI interrupt on e...
Posted on April 20, 2015 at 10:50HelloAccording to the page 18 of the ov2640 datasheet(version 1.6), device slave address is 0x60 for write and 0x61 for read, but in the camera_to_usbdisk project, only the write address is defined and used for both ...
Posted on April 20, 2015 at 17:17 Hi, I am trying to configure STM32f3discovery board as slave and arduino board as master. I tried to transmit data from stm32f3discovery board to arduino. However, the problem is the ADDR bit is never set. Can a...
