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...
Hi all,I am working with a Nucleo STM32L452RE board and I had a bit of trouble enabling the RTC clock. I am just trying to get a scope shot of the waveform output by the clock itself and I noticed it was not on by default. I attempted to use a few ex...
I am chasing reason the for last 4 mA of current that my 32F413 microcontroller draws during low current shutdown. By "shutdown" I mean sleep mode where my system is powered from a small battery with short life.A really good engineer would have equi...
I am currently attempting to port a product's older firmware that used the Standard Peripheral Driver libraries over to using the HAL libraries for greater portability between different MCUs. I a currently using the STM32L151QEHx. In the older firmwa...
I am designing a PCB for an ST micro MCU with external SDRAM.On the demo board, ST is using one series resistor termination for the bidirectional data lines. ST places this resistor at about 30/70% split of line length, where the resistor is 30 % of ...
Hi. I have a problem with ADC on a custom board with STM32L431CBY with external 24 MHz clock. Everything (UART, SPI, DAC e.t.c.) works fine except ADC. Clock initialization:static void setSystemClock(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_...
Want to know the compiler for STM3240G-Eval Board.
Hi,I am using one I2C based peripherals with Interrupt enabled.While using "HAL_I2C_Master_Transmit" and "HAL_I2C_Master_Receive", it seems to work properly with ISR.But, when I am using the following I2C_DMA:HAL_I2C_Master_Receive_DMA(&hi2c4, MPU_DE...
Hi Everyone,I found the document(AN5354) talk about 16bits ADC Max sampling Rate and I verify that on M7 Core. It's correct.My implement include Total 3 ADC 3 Channel(one channel per one ADC) run 1Mhz Sampling rate and using DMA with timer trigger Bu...
Hello,Regarding this post I am able to read my encoder value correctly. // STM32 TIM3 Encoder Decoder (PC.06:A PC.07:B) VLDiscovery - sourcer32@gmail.com #include ''stm32F10x.h'' #include ''STM32vldiscovery.h'' /**********************...
