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 am working on STM32F401RE, transmitting data via UART using DMA 1(channel 6) , also i want to receive data using DMA 1 (channel 5). I want to use the DMA in single byte transfers in direct mode. Can you help me how to do so correctly because i trie...
I am developing a project to take some measurements with ADC channels, however the values are wrong. When I connect any ADC channel direct to GND, it gives me a value about 60~80 (The ADCs are 12-bit precision) and this error propagates for any readi...
I cant find a product finder on the site. With google i cant only find apps. Anyone knows where it is? Mouser is not help either. I would like to look for uC with CAN bus.
I have the following function to sum 32 16bit signed integers as optimally as I think is possible:int16_t sum32elements2(int16_t vals[]) { uint32_t s1 = __SADD16(*(uint32_t*)&vals[0], *(uint32_t*)&vals[2]); uint32_t s2 = __SADD16(*(uint32_t*)&val...
I want to update ARR new value when timer eneble(counter is counting). What can I do to update it quickly without time latency (like setting the UG bit) ? I am using stm32f0.
I am currently using the STM32F429ZI. The ARM Cortex M4 CPU contains an MPU, but I am having trouble configuring it from the STM32CUBEMX application. I have seen examples of other MCUs having their MPUs configured from the CUBE MX, but this option do...
HiI need to control some SK9822 2020 RGB LED's.I figured out that with the information on this website I can control them over SPI in transmitt only mode.The Problem I have now is, that I need to do it using Registers and can't use CubeMX for setting...
I want to use the PVD function of my STM32U5(but I think this applies to nearly all STM32s) to detect when my supply voltage goes over(!) a specific threshold. But it might already be there when I enable PVD. Since this means looking for a zero on PV...
