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...
HelloAfter running the code for about one to two hours I always get Hard Fault exception. Readout of the registers in this Hard Fault while loop are:HFSR=0x4000 0000CFSR=0x8200BFAR=0x20020000MMFAR=0x20020000AFSR=0 Readout of the SP register shows:SP=...
Hi All,we are evaluating the possibilty to use a BiSS-C encoder in our project. First time using BiSS-C.From the BiSS-C standard it seems to me that BiSS-C can be implemented at STM32 level by mean of an SPI peripheral connected to an Rs422 transceiv...
Found a bit of an odd issue when switching from MSI (with a 160Mhz sysclock) to HSE (also with a 160Mhz sysclock).We're using the HAL_UART and its giving a error callback with a zero value uart->ErrorCode.The cause of it seems to be in the library HA...
I have timer 1 setup to PWM a wave form and timer 2 setup to PWM a different frequency wave form. I need to restart timer 2 when an output compare match (CNT = CCR) on timer 1 occurs. It appears that I can do this with master/slave configuration of...
I want to generate a ~200us pulse on the DAC (variable output) that occurs at 20Hz.The DAC itself is no problem, the 20Hz is done with a timer interrupt.What is the best way to implement the 200us timing? Preferably non-blocking, Another timer that s...
I am using SPI2 and SPI3 with DMA1 to write and read to/from peripheral chips. This works fine most of the time. At the same time I am using the stop mode to save power. Now in some cases just after leaving the stop mode, the next DMA transfer does n...
Hi,Is it possible to distinguish an STM32G0B1KBU6N from an STM32G0B1KBU6 based on the UID?Is it possible to read this UID in FW in order to recognize whether the correct controller is fitted or is this only possible via the SW interface?
Hi everyone. I am trying to communicate with a board called EVB-LAN9252-SPI via SPI, and I am only getting the datasheet-correct result for the first SPI request.If I send 0x03 and then 0x0050, I should get 0x92520001. Right now, I only get 0x9252000...
Hello everyoneIt's my first time messing around with STM32 microcontrollersA few days back I got a black pill (STM32F401CCU6 - https://robu.in/product/stm32f401ccu6-minimum-system-board-microcomputer-stm32-arm-core-board/) and an ST-Link V2. The blac...
I am using SPI4 PORTE pins 2,5 and 6. I have a 16 channel ADC hooked up to it. Everything functions as needed on the ADC including. Reset, Averaging setup, channels setup. I can see the MISO pin(Pin 5 PortE changes as the voltage changes. but 0 is re...
