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'm success create sinewave signal by using table:uint32_t Wave_LUT[NS] = { 2048, 2149, 2250, 2350, 2450, 2549, 2646, 2742, 2837, 2929, 3020, 3108, 3193, 3275, 3355, 3431, 3504, 3574, 3639, 3701, 3759, 3812, 3861, 3906, 3946, 3982, 4013, 4039...
Hello,I have a 250 Mhz oscilloscope. I am analyzing SPI clock signals at different speeds. Once I tried to have a maximum clock speed for SPIs in H745, I cant see anything from the clock pins. When I set the prescaler to 4(30Mhz) or 8(15Mhz) I can s...
Hi!I'm trying to output the LSE clock on the PA8 pin on my Nucleo64 STM32L476 board.The code I have written is the following:#include<stdint.h> #define RCC_BASE_ADDR 0x40021000UL #define RCC_CFGR_REG_OFFSET 0x08UL #define RC...
I am trying to generate hex file for my boot loader. I need a fix length hex file for my boot loader. I tried arm-none-eabi-objcopy -O srec --srec-len 0x10 ${ProjName}.elf ${ProjName}.srec;arm-none-eabi-objcopy -I srec -O ihex ${ProjName}.srec ${Proj...
I have a STM32F373VBTx serie. I know that the RTC saves the backup registers for every second. But when I restart my STM32, then the RTC sets to default date and time again due to the MX_RTC_INIT() function who is generated by CubeMX.I have two quest...
HiOur chipset is STM32G491CE.I use DAC with DMA in circular mode. DAC stop and restart. It is started previous array index.I want to be clear DMA circular buffer index.How can i do it?
#GPRS #SIM800 #OTA #STM32f4
When using LL libraries i include:DEBUGUSE_FULL_LL_DRIVERSSTM32F411xEDo i have to add something for HAL?Thanks
I am using stm32cubeide to program a stm32f030f4p6 MC. I have assigned one pin as an external interrupt and it is connected to the data output of an RF433 receiver. Here is a summary of my code:int k; int main(void) { while (1) { k=0; ...
The goal is to have the microcontroller which is in sleep mode, wake up when the voltage on a certain ADC channel drop below a set voltage.The plan was to put the core to sleep via HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI)...
