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...
Hey all,I am wondering if anyone has some insight into why i cannot get a usb connection working (trying as HID).I can power up and debug the MCU (STM32F103RBT6), but cannot get the USB to connect.For the HSI I am using 10pF for C1 and C2, and a 1000...
Is there a reference design/app note for "pass through" power delivery chargers/battery packs with these MCUs? IOW I'd like my design to do the following; -If connected to mains power/a small solar panel, charge the batteries while powering the load....
I am attempting to use a rotary encoder (Bourns PEC11R-4215F-S0024) with an STM32F091 Nucleo board. I would like to have it count a consist number of "counts" for every "click" of the encoder.Hardware Setup: Pin A is connected to PA0, Pin B is conne...
Hi all, I am trying to USB CDC communication with my STM32 nucleo board. I want to send consecutive numbers and verify that they are consecutive and calculate the data rate. I obtain errors, non consecutive numbers (irregularly), when I increase the ...
Is there a schematic or a reference design similar to the one used for the Neucleo boards? I'm thinking of spinning up my own board instead of using a neucleo, and wanted to include design elements like the debug link, boot loader link, oscillators,...
Hello I am trying to attempt a CANBUS communication between two different STM boards, I've been following the videos on the STM website as a reference and I got the LOOPBACK Mode to work with one STM board but I am having trouble getting the NORMAL m...
I try make"design system that sets outputPin (should be digital gpio output ) high for 0.25 secs,and low for 0.25 secs."and i use GPIOA_PIN4(input) and GPIOB_PIN0(output), I'm new to stm32, I'm having trouble with the timer.I try use tim, how can ...
Is there a cheaper alternative to the STM32373C-EVAL discovery board? I wanted to use the STM32F373 part.
I'm writing a bootloader and trying to use HAL_FLASH_Program() and noticed that a word is listed as 32 bits. Is this an ST specific word size? I've always thought that a word = 2 bytes = 16 bits. But it appears that if I want to write a word with ...
Hi everyone,Do you think there is any reason why a set of instructions (20 lines max.), including UART transmission, works fine within the while(1) block but it doesn't work if that exact set of instruction is in a function, within the same while(1) ...
