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...
Hello,I am trying to access an external flash memory (32 mbit) using stm32L4. Stm32L4 has OctoSpi. i have configured the OctoSpi with dual quad disabled but yet, i am not able to access the external flash mem. The external flash memory supports sin...
According to the STM32L433xx/443xx device errata, the result of an ADC conversion done more than 1 ms later than ADC calibration or previous ADC conversion might be incorrect.The workaround suggested by the errata sheet is, "Perform two consecutive A...
Hello,i am using stm32f103C6 ( 48 pin device) and i use TIM1 Channel 3N to generate a pwm via PB15 pin. The tricky part is that i am using SPI12 in receive only master mode.Therefore MOSI pin is not used, but since i have little pins available, i...
Hello, I have two different projects in parallel right now, both of which use STM32G0B1 MCUs. On both projects, with completely seperate hardware, the VREFpin that connects to the internal VREFBUF peripheral is innacurate. These pins are just brought...
Hey all, I'm trying to generate DMA PWM for a row of 3 Neopixels. I succeeded on a Nucleo-based L496, but translating to a L4P5 target (custom board) results in no output on the GPIO at all. I've compared the generated HAL code for both and cannot fi...
Started a project based on the STM32L010 which needs to receive six bytes from the UART. Works fine if I use it in interrupt mode. Does NOT work if I use it in DMA mode. Saw multiple posts about the DMA needing to be init'd before the peripheral in q...
Hi there,I have a STM32L431RCT6 microcontroller. I wish to write some data on it. let's say I want to write 2 at 0x08009000 Address.here is my code#define FLASH_USER_START_ADDR ((uint32_t)0x08009000) #define FLASH_USER_END_ADDR ((u...
We have facing issue on microntroller we have recieve we have serial product and curretly we are using STM32F072VBT6 controller but we have order new lot and we are recieve STM32F072VBT6 2 and both are behaviour diffrent so what is major diffrence be...
When we test adc small signals, we found all spi have impact on adc1 and adc2 module, which leads unexpect singals even we use fund HDs of it.Detals as below:--Environment:Save 6400 points at different conditions,1. spi2 or spi4 work and really has i...
