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 September 19, 2013 at 17:37Hello everybody,Is it possible to link same pin number of different GPIO ports on the same EXTI line ? For example, create an interrupt on line_0 for the GPIO pin A0 and the pin B0. It seems impossible to achieve...
Posted on March 31, 2014 at 02:51I am experimenting with the STM32F429 and wish to use the LCD-TFT controller (LTDC).I am interested in generating monochrome 640x480 VGA video and hence only need 1-bit output rather than 8-bit RGB. Does anyone know ...
Posted on March 31, 2014 at 02:29Hello, I am trying to activate the interrupts on PC4-7 so that a flag will appear whenever these pins are set high. I have the base structure of the code completed, however whenever I try to place a break point to se...
Posted on February 17, 2014 at 16:07 Hi, I'm using the F407 (Discovery) as a SPI-Slave with DMA enabled and a ''data ready'' signaling line. I'm currently trying to transfer data in dual buffer mode (the host cpu might also send configura...
Posted on March 29, 2014 at 02:21 Hi, I'm entering in STOP mode with the command: PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); But, when it resume from STOP, I cannot write to EEPROM anymore. I'm unlock...
Posted on October 29, 2013 at 15:56Hello everybody, I'm looking for a working example using OUT Endpoint on STM32F4 Discovery board. I have no success with it. I modified Demo sample for an OUT Endpoint and Custom usage, and try to send one byte rep...
Posted on March 30, 2014 at 14:35 Guys, How can I configure all the pins on PORT D as output ? I see for one pin : 1. GPIO_InitStructure.GPIO_Pin = LED1_D_PIN; 2. GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; 3. GPIO_I...
Posted on March 30, 2014 at 14:08Hi,I am currently using the CAN peripheral in STM32F3-Discovery. I am not sure if there is a mistake in the reference manual, please see the image attached:Shouldn't be the arbitration field for Standard Identifier d...
Posted on March 29, 2014 at 17:53 Hello stmGuys. I'm having a problem configuring my DMA. I've tried everything I can imagine and it still doesn't work. I want the DMA to transfer data from a memory array to the GPIOD->ODR register. Here is my DMA...
Posted on March 30, 2014 at 11:36Dear, i am trying to get coordinates from a touch screen using SPI2 of STM32F405, but sometime i get nonsense values. I am wandering if maybe pull-up's are needed on miso / mosi / cs etc. Reagrds, angelo
