Resolved! STM32G473 Unable to use PA15 as GPIO when debugging in SWD mode
I have a board with a CAN transceiver connected to a STM32G473RE using PA8 and PA15 for RX and TX. When I configure the GPIO for PA15 into AF11 to enable the CAN module, I lose connection with my STLink debugger. (I am using the STLink built into a N...
STM32F103ZET6-TIM1-Output AB pulse
When I use the TIM1 peripheral of the STM32F103ZET6 chip, when using the flip mode, OC1M = OC2M = 3, ARR = 300, CCR1 = 150, CCR2 = 300, but the first edge is all output high at the same time, theoretically The OC1 channel will output the high level a...
Hello, for seat reservation, I already have the board.
Purchased directly from Digikey.
TGFX, How to manage common screens for different projects?
Hi, We have two similar projects that have many files are in common. Many screens are also used in common. Currently, there have two TGFX designer projects to make GUI code for them. We need to figure out an easy way to manage these common files, dir...
where to find the reference/application note to design a fitness tracker with STM32L4?
I am always curious about how does a fitness tracker work. So i did a preliminary search and found this page. https://www.st.com/en/applications/wearable/fitness-trackers.html#overviewnow I would like to know how to design a schematic based on stm32l...
Resolved! How does the noise error detection of a UART of the STM32F4 series work?
Hello Community,in my application data is transferred between two MCUs using a UART. One of these MCUs is a STM32F429. It often detects frame and noise errors. I am aware of how a frame error is detected, but I can't find any information in the Refer...
Is it possible to use the STM32L476 in a Dual SPI line Slave Mode?
Hey, Can the dual SPi Line be used as a slave? I should be able to interpret 2 bits with a clock of 16.368Mhz. in connection with the dma, of courseIs that possible with an STM32L476G Discovery board?
Value of VREFINT_RDYF
Hi,I am reading value of SYSCFG_CFGR3_VREFINT_RDYF to be "1073741824". How do I interpret the value of VREFINT_RDYF from the value I am reading?
Resolved! STM32H747 LPTIM4 PWM output in system STOP mode not working
Hi everyone, we have a problem using LPTIM4 PWM output on STM32H747I-DISCO when system enters STOP mode.In this project, I need two independent PWM outputs with fixed frequency to work, while system goes to STOP mode to save power. LPTIM1_OUT & LPTIM...
