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...
Hello everyone,I'm working on a custom board that uses the STM32H723ZGT6 together with the LAN8742A-CZ-TR Ethernet PHY.During the call to HAL_ETH_Init() in the stm32h7xx_hal_eth.c file, the initialization fails and gets stuck in this loop: /* Wait f...
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 ...
What I want to achive:I2S Audio Output on the included Arduino Header of the STM32F746G-Disco Board to drive a MAX98357A class-D amplifier.PB4 I2S2_WS on Ardunio D3 PI1 I2S2_CK on Ardunio D7PI3 I2S2_SD on Arduino D13To ensure that no configurable sol...
Hello everyone! After countless hours of self-grind, talking to different LLMs about it (and mostly failing), I may have started to get some faint idea about what I am doing. I am mostly writing this post for a sanity-check. Currently, for a medical ...
Hello,I'm here on H753, external clock, CPU clock configured to 400MHz. Setup code is generated by CubeMx.If I execute a HAL_Delay() takes twice the time as expected, e.g. 2ms instead 1ms. I checked via GPIO toggle with a scope.The MCO output is corr...
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,I am using Tower Pro SG90 servo motor interfaced with STM32F401. Timer 2 is used for generating PWM and timer 5 is used for generating the delay. I tried multiple code changes by myself and also took help from internet, but the servo jitters a lot...
