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...
Hi All,I am trying to generate required no of pulses using PWM. This is to implement to control stepper motor with position control. I use HAL_TIM_PWM_Start_IT to start pulsing and count the no of pulses in HAL_TIM_PWM_PulseFinishedCallback. I notice...
Hey folks!Got some questions around synced timers on STM32F401, where the aim is to have two timers start together, where one timer has a period an integer multiple of the other. I've got what I need working but how it works, doesn't add up.Here's th...
I tried to use DSP CMSIS Library, I included the libraries and adjusted the Paths and Symbols but when I tried to build the program I get this notification.Cannot run program "arm-atollic-eabi-gcc": Command line too longHow I fix this problem ?
Hello everyone,I'm just starting to learn assembly for the ARM architecture. I'm also in general a beginner with the assembly language I have just some minor experience with the x86 assembly but that's about it.I'm following a course on Udemy and I h...
Hi,I have a custom board with an STM32G474RE. I use 3 CANs with 3 independent CAN tranciever on the board. I tried sendind CAN message from CAN1 to CAN3 but the message is not received. At least the callback funnction is not called. I used an oscillo...
I want to print out 5 waveforms during 1us.So, I printed out 5 MHz period PWM from TIM3.We tried to change the duty cycle of TIM3 to zero at interrupt time by running a 1 MHz timer counter on TIM6. However, it was confirmed that TIM6's 1 MHz timer co...
when i press debug button Target Software Startup Script Error comes.there is no change in startup script file it is by default.so what is the problem and how to solve it?
I think the article here:https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesis wrong. In solution 3 it invalidate D-cache before reception. This doesn't make sense, it has to invalidate the D-cache after reception.
Hi,I have a custom board with STM32L010. I used STM32 cubeMX to initialize the GPIO,I2C,SPI,ADC,USART,LPTIM2,CRC,DMA and RTC. Then I de-initialize everything except GPIO and put the controller in sleep mode. The current consumption still is 250 uA af...
I'm using this code to read from a flash chip with quad SPI: // send read command and read page data OSPI_RegularCmdTypeDef sCommand; memset(&sCommand, 0, sizeof(sCommand)); sCommand.OperationType = HAL_OSPI_OPTYPE_COMMON_CFG; sCommand.FlashId = ...
