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 want to read 8 bit ADC value from ADC2(PA1 pin) and use it to control a LED which is connected to DAC1(PA4 pin). I wrote a code(using registers) as below, however, I cannot read the ADC value(I tested it on STM Studio). Where is my problem? T...
Hello,We need to track milliseconds of Edge Change time of External Interrupt. So, How Can this be done?Thank You
I have the latest FP-AI-VISION-1, the 747i-DISCO and the BCAM board. I can see the image, but cannot storen anything to a SDCARD. I tried an SDCard that is readable in the original 747i-DISCO demo code, so at least the interface and card seem to work...
Hi,the STM32L011E4 has a R_ADC of 1kOhm max according to the datasheet. Does this hold true for standard channels as well, or do standard channels have a higher impedance? The table with R_AIN_max isn't super helpful in this regard as my calculation ...
To illustrate it's work I'm running this code:while(1) { HAL_Delay(1); HAL_GPIO_WritePin(test_GPIO_Port, test_Pin,GPIO_PIN_SET); HAL_SAI_Transmit_DMA(&hsai_BlockA2, (uint8_t*)&noisebuf[0], BLOCK_SIZE*BUFFER_BLOCK_COUNT); } void HAL_SAI_T...
Hi I program a STM32F103 chip and work on a GPIO driver. The specs tells you clearly: The peripheral registers have to be accessed by words (32-bit) 9.2 GPIO registers RM0008.It doesn't use the word must be accessed. (Im planning to use the specifica...
How does the STM32 knows where should the .BSS section be addressed,and what's the range,when the chip startup initially? We know that firmware downloaded into the flash contains section information like .text ,.data ect,while .bss section should be ...
Hello,Code that was compiled for stm32F407 ( core M4) has an bug that accesses null pointer. The assembly code is as follows: STRB r1, [r0, #0x01]Where r0=0 and r1=0.Although MCU accesses null pointer, it does not enter hard-fault.But, the same c...
Hello,I am using an STM32H7B3I-EVAL board with a STM32H7B3LIH6Q MCU. I am looking to use FDCAN to communicate with multiple nodes and someone recommended using mailboxes for messages sent/received. The documentation was unclear, so I wanted to ask if...
