Hello!I just received some custom PCBs with the STM32H747BIT6 MCU, but I’m having trouble connecting to it. I’m using a J-Link V12 and initially tried to establish the connection with jlinkexe. It correctly detects the voltage, but when attempting t...
The pins for USART3 are listed as PD9 and PD8; however, these are not available on the microcontroller.What are the correct pins? Similar to posts:https://community.st.com/t5/stm32-mcus-products/stm32h5-bootloader-uses-usart-pins-that-do-not-match-ro...
Hello - I recently took a working design and upgraded from the STM32L4 to the STM32L5. I'm having a major issue getting the i2c bus to work properly.I have SCL (PB11) and SDA (PB10) configured.I have pull-up resistors (4.7 kohm) on each of SDA/SCL. I...
I am designing a PCB that uses the STM32L433RC.I just checked the pin out of the PCB footprint with the datasheet, but then got confused as there are two different pin outs for what seems to be the same device.The footprint I am using matches figure ...
Hi,I would like to implement a USB -> SPI flash storage solution. There are several guides and examples already available to do so (also the tinyUSB ones), so I think that should not be an issue.However, due to physical constraints of my project, I d...
I'm getting unexpected signal in PWM output on timer1 channels.Signal screenshots are attached.getting unexpected signal (around 500nS) in between PWM duty cycle pulse. Below is timer configuration : NOTE*: CCR values changes with software as require...
For my project I'm using an STM32F743VIT6 with ADC1 and ADC2 in 16-bit differential mode.In the reference manual (RM0433) §25.4.7 it is written:Converted value = ADC_Full_Scale / 2 x [1 + (VINP-VINN)/VREF+].For 16 bits, ADC_Full_Scale is 0xFFFF. What...
Hello,I have a question about the usage of the MCE in the STM32H7RSI have the STM32H7S78-DK boardI'm starting with a project that show images to LTDC with images on the flash (copy with DMA2D) and the framebuffer is on the PSRAM.My project works with...
Hi All,I have written a baremetal code to initialize the USART2 of STM32F401RE and print HELLO WORLD. The code does not use HAL and rather accesses and writes to USART2 peripheral registers using the C pointers. I have cross verified the code multipl...
I'm working on a DMA routine for my SPI DAC, and I've loaded up a buffer with the commands to make a sine wave. But when I check it with the oscilloscope, it's just stuck at 2.05V, which is actually the very first command in my sequence.I've spent ho...
