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...
Hi,Currently I am using STM32L4R9 discovery board, which has 16-Mbit (2MB) PSRAM. I have been able to allocate static memory inside PSRAM by using following code and also by changing linker script file (.ld). I have attached my edited linker script w...
In our application, STM32 micro controller USART protocol is used as UART full duplex mode. what will be the conditions to use USART as UART full duplex mode?Already I have disabled CLKEN bit in USART_CR2 register. Though, disabling CLKEN bit in US...
Hi, I read input PWM signal from RC radiolink (done): duty_cycle range 675-1347And now I want to convert this signal to analog to ON/OFF led, I used MAP funtions and I don't know how to move read_RC to ON led, something's like analogWrite (read_RC, L...
Question: I have an example here that assign TRACE_IOEN and TRACE_MODE to sync 1 bit from the DBGMCU_CR register (Address: 0xE004 2004) by using this command: mmw 0xE0042004 0x00000060 0x000000c0. What the 0x000000c0 doing in the mmw command ? my bas...
Hello, this is my first project here, I'd like to get some guidance please. I work with STM32L073 Nucleo board, and along other features successfully configured Analog Watchdog Interrupt on PA4 pin, it works great in normal mode, but not when the IC...
it passes the 16bit test but fails the 32 bit testwhen i check a good board the D1 signal is high not fluctuating.any advice?
Hello everyone,I'm trying to to use TIM2 as interfacing timer to capture 3 hall sensor inputs. I set the TIMx.CR2.TI1S bit to XOR combination and use OC2REF is sent to TIM1 through TRGO as exactly said in RM0008 Interfacing with Hall sensors section....
Is it possible to ensure that the systick is handled (or the timer that handles the ms tick), and at the same time not interrupt higher priorities unless the irq has been busy/active for example 1 ms?I guess the question applies for arm M0 - M4 in ge...
Hello,How long does the __NOP() function last?Is it the time of a cycle? Or 1/F = cycle time?My MCU is an STM32F401RE, and I understand that the maximum frequency is 84 Mhz.So 1/84 Mhz = 11.90 ns, is that the time of a cycle?In my case, if I loop 14 ...
I'm trying to configure the Bootloader for a STM32G4A1KE processor, but in the AN2606 I cannot find any information regarding this processor (family STM32G41). Although it is listed in the introduction section of AN2606, no further information is gi...
