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...
ADC1 clocked @ 65 MHz, pre-scaler of 8, 7 channels active, 640.5 cycles/conversion, 256 oversampling, interrupts, scan mode. The numbers suggest all channels will be converted 1x in (8/65000000) * 640.5 * 7 * 256 = 141 ms. But when I look at uwTick b...
Hi,When i use HAL_CAN_Transmit to send a CAN message on STM32F4, if say I am in error passive or bus off condition, what error does the API return? If I am in error passive, what is the best way to reset the error count to 0?Where can i get the error...
Hi there! I have trouble escaping CAN error passive state on STM32F417VG microcontroller.The goal of my application is to automatically detect external CAN bus baud rate (either 250kHz or 500kHz) then send CAN messages on the bus at the right frequen...
Hello everyone,I am working with the STM32G0B1KEU6 microcontroller, which comes in a 32-pin package featuring only ports A, B, and C. According to AN2606, the internal bootloader uses the following pins:FDCAN1_Rx pin: Input PD0, used in alternate pus...
Hi,I understand this has been discussed before, but can we please get an official explanation of how the dma tail pointer works in the Stm32H7 eth mac ip block? It's extremely difficult to write software to support the eth mac when the docs and examp...
Hi, I am working on a realtime audio DSP product using the STM32H7 with a AS4C4M16SA-7BCN SDRAM chip for long delay line memory. I am using the FMC controller with the settings in the attached photo:The product processes an incoming audio stream in r...
We have product running with STM32L162ZET6 successfully. Because of memory constraints on future developments , we wanted to use alternative part for it. During research, we found STM32H533ZET6 by Hardware engineer.After comparison, we found that arc...
Good morning everyone,I am trying to modify a bootloader that is already in production and working.My problem is that if I call the JumpToApplication() function right after peripheral initialization (as the production bootloader does), everything wor...
HiI'm designing a PCB using the STM32H735 based on the eval kit STM32H735G-DK.Since the HyperRAM S70KL1281 on the eval is EOL I'm looking for an alternativeI have read a few posts with issues on this subject and I'm usure which part i should go with...
Hi,i'm using a STM32L031. In my code i first initialize the MCU (FLASH, CLOCK, INTERRUPTs, GPIOs), start the LPTIM (running on LSI), then slow down the MSI clock, start the timer22 for PWM and go into low-power sleep mode. When i let the program run...
