The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I have inherited a PCBA that needs to generate a fixed number of PWM pulses on TIM2 CH4.I have successfully setup TIM1 as the Master (with repetition count = 0) and TIM4 as a Gated Slave.TIM1 CH1 is generating 2kHz PWM indefinitely.TIM2 CH4 is genera...
I'm sure everyone else has noticed how the two pins to VCAP seem to be placed just over a complete side of the package away so there is bound to be some resistance/inductance in the tracking. I was wondering if anybody has ever hit problems with thi...
My current code configures the RTC and updates date/time on initial turn on only.void set_date(void) { /* Select LSE as RTC Input */ __HAL_RCC_RTC_CONFIG(RCC_RTCCLKSOURCE_LSE); /* Enable RTC */ __HAL_RCC_RTC_ENABLE(); RCC_OscInitTypeD...
DocID024030 Rev 9 states:4. If VREF+ pin is present, it must respect the following condition: VDDA-VREF+ < 1.2 V.Normally, I would just make changes to satisfy, but a change at present product development stage is very costly. Using LQFP144 pkg if ...
Hi, I am using stm32f103vc(100pin-LQFP) controller in my board while i try to program my board using st link v2 programmer it shows error message like "dev target held under reset".Programming pin connected as follows.SWCLK--->PA14SWDIO--->PA13GND...
Hi there,i want to implement my MCU to program a FPGA via SPI. Is there any helpful guidelines on this topic? I am a newbie with STM and i hope that someone can help me here.Thanks in advance.
Hi all,I am looking for Gnu C linker scripts. I found linker scripts inside the Cube bloatware after waiting 2 hours for the download to finish (yes, not everybody has Gigabit internet) but:they don't work with GCC. For example __data_start is not...
Hi,We are using STM32F746IGT6 MCU in our circuit and it seems that when i connect ESD diode to to NJTRST/PB4 pin for protection, the MCU FW sometimes works at power up and sometimes don't (very random).It happens to me so far with two different ESD ...
Hello, I am making a module using STM32L476RET6 .I have a few questions. In various examples, most of them use DOT-LCD. Can I use the STM32L476RET6 with TFT LCD? 2. If it is available, Can I connect 'LCD DATA' to 'LCD SEGMENT ' pin?Thank...
