hai,i am designing using STM32F051R4T6TR.I have configured port F for I2C but couldnt find that in the additional functions list in datasheet of the ic found on the last page.I found the additional function list of both PORT A and B in the datasheet ...
As stated in the Reference manual. I configure the master ADC1 to get the trigger from the TIM2 TRGO and this ADC1 is working when started. ADC2 and ADC3 start only when I configure JEXTEN (=0x01) and JEXTSEL (=0x03) in CR2 of the according ADC. I do...
I have a working USB2 (ULPI) device mode interface, and want to detect cable removal. There appears to be provision for this: OTG_GINTSTS has SRQINT and OTGINT bits and OTG_GOTGINT has the OTGINT bit, but I do not seem to get any response to cable r...
I'm sampling a single ADC with 3 channels using DMA.Let's say the requested data size for each channel is 1024. So this is the code for starting DMA:uint16_t buffer[1024*3]; HAL_ADC_Start_DMA(&hadc1, buffer, 1024*3);Now when HAL_ADC_ConvCpltCallback(...
Posted on May 19, 2018 at 12:48Hello , I am using stm32f446re nucleo board . and i face some issue in timer input capture . here i am using 2 timers TIM6 ( for time base generation ) and TIM2 (free running input capture purpose)actually my code is w...
On STM32L476 Discovery and TrueSTUDIO 9.0.1, USB CDC fails on Windows 10, if code is generated by STM32Cube MCU package of STM32L4 version 1.12.0. Back to version 1.11.0, it works fine. Furthermore, at 48 MHz USB clock, if SYSCLK = 48 MHz, the USB c...
I am working on a very power sensitive application involving a STML431 processor running only off a battery. I plan on using Shutdown mode most of the time with an hourly wake up. I am looking for 1 measurement (maybe averaging a few actual samples)...
Hello,I'm having some trouble using the timer based interrupts.I have some very basic experience in mcu programing but I'm new to the STM32 platform and I had to adapt to it rather quickly. Therefore I lack some of the basic knowledge.My first questi...
I have been trying to perform SPI communication and observe outgoing and incoming data through MOSI & MISO. There is a weird problem in SCK weveform There are the codes I wrote :#include "stm32f10x.h" #include "stm32f10x_rcc.h" #include "stm32f10x_gp...
