Dear all,I’m seeing unexpected behavior on an STM32N657. A timer is configured to generate an interrupt every 1 ms, and this works as expected.I would like to use WFI to stop execution and wait for that timer interrupt. I surround the WFI with the u...
I have had a board assembled and want to check they have fitted the STM32 in the correct orientation. Pin 1 on the PCB is shown by the white triangle. But it’s not clear from the package where pin one is because there are two circles in opposite co...
I am trying to read ID and to write and read the data from the flash W25Q16JV with SPI2 of stm32L452CE connection, I am not even getting the ID from flash but SPI tx rx is getting HAL_OK. This wiring is working other code and providing unique ID from...
HI I AM FACING ISSUE WITH TIMER SYNC WITH SAME LENGTH TIM2 MASTER ANDTIM8 SLAVE HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_4, (uint32_t *)gPWMData1, gPWMData1LastIdx); // IN THIS SAME ARRAY PWM ALWAYS GENERATED IN DMA HAL_DMA_Start_IT(&hdma_tim8_up, (...
I'm trying to program a virgin SYM32G0B1 with the code I've developed and successfully run on the NUCLEO-G0B1RE/NUG0B1RE$AU2 development board. I'm using the STM32CibeProgrammer 2.20.0 software and an FTDI cable (TTL-232RG-VIP-WE with the Vcc line co...
Hi all,I'm having trouble debugging using STLINK when the STM32U031C8U6 microcontroller is in stop mode or running at a low frequency clockI already tried to:enable in the STM32CubeIDE the "Debug in low power modes" option (Debug Configuration, Debug...
Spent two days of trying to see printf via USART1 from U585 and U575 boards. Was trying to load BLE via DFU on B-U585 and get it work but USART1 became silent. (Wrote separate post on B-U585I-IOT2A as documentation nightmare). Problem: USB-C + STLIN...
The STM32F107Vx has 2 CAN interfaces.In the TRM RM0008 Rev 21 dated February 2021 on page 115 I can only find one entry to enable the CAN clock, bit 25. What CAN clock does this bit enable? CAN1, CAN2 or both? Or does the reserved bit 26 enable CAN2 ...
Hi, I'm using an STM32L431CCU6TR in a low power application, which uses a system basis chip to control the voltage rails to the system. After a predetermined timeout period, the SBC cuts VDD from the STM32, and can only be woken by an external influ...
