hello,i am working on project with a stm32wle5jc and am fairly new to stm tools. all was working well but after a little break on another project it will no longer flash the board with the stm ide (1.19.0) and says "No ST-LINK detected! Please connec...
Hi all: I have a general question about whether STM32 peripherals need to be clocked permanently. I am using an STM32G0 at the moment, and I am disabling the USB C Power Delivery "Dead Battery" feature, in order to make sure that the internal 5k1 pul...
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...
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, (...
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...
I'm experiencing a very, very strange behavior when running debug sessions in STM32CubeIDE. Sequential sessions alternate between correct execution of my main() entry point (and execution stops there, as expected) and unexpected entry into the bootlo...
