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 everyone.I am beginner in programming, and I was not able to find working example for USART 3,4,5, and 6 for STM32F030CC. Until now I was just using USART1 and 2 to send messages and receive message but while i tried the same configuration for ...
Hello,I just got an STM32G071 board - NUCELO-G071RB with an unusual label "NUG071RB$AU1".Is it some kind of preproduction sample?Thank you,David
Hello,On STM32F429, I'm using RTC. It is clocked by the 32KHz LSI.I set async prescaler register to 127 and Sync prescaler register to 249.The total prescaling factor will be 250*128 = 32 000.Exactly what I need to provide 1Hz to RTC.After testing, i...
Hello,I am using a Bootloader which jump to operational application.the Bootloader configures SRAM, so that operational does not need to do it again.Bootloader is baremetal , and operational is freeRTOS.I use IAR.Everything works well if I reset the ...
I made several custom PCBs using the STM32F446RET6 chip. At first the CAN seemed to work fine, by reading it out with a Kvaser (CAN sniffer). However problems arrived when attaching other devices (like a beagle bone) to the CANbus. The beagle bone on...
I use ST-Link/V2, Segger J-Link and Segger Flasher ARM to program STM32F303 and STM32F730R with SWDIO/SWCLK signals without problems. However, I cannot get it to work on the STM32G071KB. Is there anyone who does?
hello everyone,i am new to STM32 controller series,i am trying to read mutli channel ADC with help of DMA and Interrupt.but facing issue.i am not getting ok status from"HAL_ADC_Start_DMA" this function. can any-body help me out.please find below con...
I am trying to figure out how the FMC of an STM32H7 needs to be configured to work with an FT232H in CPU FIFO mode.The FT232H requires that for a write operation the NWE signal goes low after the data pins are set:From what I could find in the refere...
I am using a STM32 Discovery Board with external SD Ram. I used the memory in RAM so far by creating a Ponter in the SD-Ram address area.But now my program is getting more and more complex and I could use a memory manager. Can I use the Malloc, Callo...
