The goal of my project is to turn on an LED on the recieving side through CAN. Both my reciever and transmitter have the transciever circuit. Both are Nucleo boards, TX: F303RE, RX: F446RE.The data i am sending through is 16-bit, but as long as my re...
Hello members,Until recently, I was using a G473. There, I ran code from the ccmram. That worked without any problems. Now I have switched to the H533. For performance reasons, I want to run the code in SRAM1 0x20000000 - 0x2001FFF. I want to keep th...
Hi all, in RM0456 is plenty of examples with using LLI but only one without it. And even that contain a block diagram that does not explain anything. Also AN5593 does not mention cyclic transfer. So, here i am. Does this diagram means, that if the...
Hi, I’m working on an STM32L431CBT6 project where I enter STOP2 mode and measure ~1 µA current, which is great. However, I need to use PA0 as a GPIO input to wake up the MCU from STOP2. When I configure PA0 as an input (no pull, or pull-up/down), my ...
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...
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, (...
