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...
So the datasheet says "Min VREF+ Positive reference voltage - 1.8 V (1)(2)(3)", and note 3: VDDA -VREF+ < 1.2 V, so with VDDA at 2.925v, VREF of 1.755V would be permitted? Its a bit confusing to me at this point!Given the ADC 12 bit resolution, the L...
I made a simple program on an ESP32 to send dummy data with something like this $DUMMYDATA,0,1I've tried using another ESP32 as a receiver and it works perfectly. My goals is implement the same thing to my STM32F103C8T6. Here's my code for the first ...
Hi All,I'm working on a STM32H7 custom board and I'm trying to access a Cypress S70KL HyperRam through the Hyperbus protocol using the OCTOSPI1. I'm able to access in read/write the HyperRam but I want to use the delay block therefore in CubeMx I ena...
I am trying to migrate our current design from L031 to G031 for the additional 32K firmware space with the same pin layout. One of the requirements is to store integer counters in the flash memory, and the counters get updated roughly 50K times over ...
What is the role of syscalls.c file in GNU ARM(STM32 for instance) based projects? I found 2 ways of successfully building the project1. Delete syscalls.c and include -specs=nosys.specs in the linker flags2. Simply include syscalls.cWhat is the funda...
Hello again everybody. I have run into the following problem: I try calibrate the ADC1 and plain calibration seems to work just fine (apparently), but as soon as I try to follow the Extended Calibration procedure, described on page 1007 of the Holy U...
Dear Sir.I need the output of the ADC to be signed .the adc is configured . /** Common adc1 configuration */ hadc->Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc->Init.Resolution = ADC_RESOLUTION_14B; hadc->Init.DataAlign = AD...
I cannot get the CAN bus CAN1_RX0 interrupt to fire. I have two other development boards (STM32429i-EVAL1 and STM32373C-eval) that both work correctly. I am using the same code in each setup thru the ST MX and IDE. The Eval boards have built in C...
