STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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 do some serial interface clock with timers chain on stm32f407.Thats work, but generate little bit lower count of impulses. where is my trouble? len is about 16 384, overall pulse count len*16.I miss about 200*16=3200 pulses.Thank You!TIM2->PSC=0; ...
Hi, Currently i am using STM32L082CZ processor and debugger tools as ST-LINK V2 B2019-51.When I enter debug mode, it will update the status/flag/watch variable upon reach breakpoints. The debugger window show on Keil won't update during run time, i...
I understand the sampling rate for 16-bit can be a maximum of 3.6Msps depending on the chip package, number of ADCs, oversampling, and interleaving or regular.. I'm doing a regular 3 channels 16-bit scan from a single ADC, no oversampling.The app not...
Hello,I am observing a strange behaviour of the first few PWM pulses after a change in duty cycle. I use HAL_TIM_PWM_Stop, HAL_TIM_ConfigChannel (with the changed Pulse) and then HAL_TIM_PWM_Start. What happens is that for around 1 millisecond the ...
The line where the external interrupt is set SYSCFG->EXTICR [2] |= (3 << 12); I want to set it for port D pin 10. How the masking and unmasking is done for port D?
Hi,I am designing a st board for the first time. First, we made all the improvements on the blue pill, which is STM32F103C8T6. When this wasn't enough, we switched to STM32F103RCT6.I am currently drawing a schematic of this card and was confused in ...
Hi everyone!I'm implementing a 4k XMODEM bootloader for the STM32G030F6. The application starts at 0x08001000 (page 2)I want to erase page 2 (0x08001000 - 0x080017FF) and only program rows 17 to 19 (0x08001100 - 0x080017FF). I want to save row 16 in ...
Hallo. In other mcu (not ARM) i’ve worked in the past, there were possibe to move some parts of time critical code to ram, and run them from there to get the best performance, since the flash mamory access were slower then the ram access. In STM32 mc...
Hello, I would like to know if it is possible to measure the length of a really long and thin copper wire. The length ranges between 5 - 15 km. I think TDR (time domain reflectometry) would be the best method for it. My plan is to generate a pulse wi...
