Posted on March 16, 2018 at 19:50 I'm writing a crude memory diagnostic for SDRAM (just to see if I can). The code accesses SDRAM using a pointer. __IO uint32_t * SDRAM_ptr; SDRAM_ptr = (__IO uint32_t *)0xC0000000; Using this pointer in a loo...
Posted on March 16, 2018 at 00:30I am trying to use USART2 of my Nucleo L476RG board. It is connected to the UART of the ST-LINK on the board. I'm trying to implement a simple line-based protocol (every message is terminated by \r or \n). For starte...

Posted on March 17, 2018 at 10:02We use micro controller STM32F103RBT6 & stepper motor driver IC TB6560AHQ.we have found the problem at Reset pin of stepper motor driver IC. Circuit is attached.Initially machine works properly. but after some time m...
Posted on March 16, 2018 at 22:20Hi Community,On a STM32F407 MCU, I wish to generate a single pulse with TIM4 PWM when triggered by ADC watchdog interrupt, with least delay possible.Taken from the reference manual RM0090 One-pulse Mode section, ...
Posted on March 16, 2018 at 16:56Hi folks,I am a little confused by the AF selection on some pins in the case of using multiple I2C's.I am bringing up a new board where board I2C1 and I2C2 are being used on an F4 micro.I2C1 is on PB6 & PB7, I2C2 is ...
Posted on March 16, 2018 at 09:21TIMx->PSC=16; has no effect. Can you please explain why? Is there any pre-condition to load the prescaler?
Posted on December 22, 2016 at 05:40hi,i recently got stm32f407vg-disc1(discovery) and started a project.i want to power up the board with external battery(5.1v, 2.4a) through micro-usb port(cn5) but it's not working at all.it's working fine when i ...
Posted on March 16, 2018 at 18:58I would like to know the number of possible flash memory erase cycles apply for the STM32H743. I could not find the spec. in the Reference manual or on the ST home page. Is it like 100 000 write/erase cycles? or le...
Posted on March 16, 2018 at 16:13I know F1 it ancient hardware but I found the board interesting:http://www.newark.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=-1&urlRequestType=Base&partNumber=64R5913&storeId=10194
