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 need a to read and write a simple 16 bit user configuration value that's stored in non-volatile memory. The STM32L0xx is famously short on memory and as such bringing the entire HAL in is out of the question. It swells up the code space well beyond...
I am using 6 channels adc with 46uSec sample rate. the reading is pretty good with dma. and I use TIMER trigger adc reading and get data from dma call back function. but every time I only get one sample for each channels, it is possible to set multip...
I am trying to measure the frequency of a square wave using TIM1 in direct input capture mode (STM32F3-DISCOVERY) . I can measure the frequency successfully , but i want to add an input prescaler, no matter what the value of prescalar i set i get the...
In the STM32H7 datasheets, page 23 (H750) or 26 (H743) - ST says the device has 2KB user option bytes flash area. Does anyone have idea if this is a typo? Or how to access this memory?If it really is there - it has a good potential to be used as conf...
I am using nucle-h745ziq ,SPI1 as Full duplex master and SPI4 as Full duplex salve.And both have same freuncy 25MHZ .And spi1 prescalar is 2.But SPI4 is not start the communication.Both structure parameter are same.In spi.c libabry I am uing if(HAL_...
We have three options to select encoder mode In SMS bits (Slave Mode Selection) of TIMx_SMCR register. Based on the description following each mode in this register, counter counts UP/Down on each TI2FP1/TI1FP2 edge based on the TI1FP2/TI2FP1 level o...
*How we can transfer (eg:2 bytes of ) data through simple GPIO pins without using any of the communication protocols (uart,spi,i2c,etc..)
I have a STM32F446 core and the Peripheral clock is 45 MHz. I am looking at the RM0390 Rev 6 Section 30.7.7 Bit TimingI am looking at the documentation Figure 395. Page 1063/1347I want a bit rate of 1 million bits per second (Mbps)In my calculation u...
