Hi, The datasheets says (P173) - the VREF– s available only on UFBGA176+25 andTFBGA240+25. When VREF- is not available, it is internally connected to VDDA and VSSA. Our ADC input signal goes to both positive and negative. Questions:1. What the par...
Hello,I am working with the STM32H745 microcontroller and planning to upload firmware via USB DFU. I need clarification about the BOOT0 pin configuration for this process:For USB DFU mode: Should I set the BOOT0 pin to 1 (Boot from System Memory) bef...
On the stm32h750, I want to use 4 channels to implement pwm waves with different phases in the output comparison mode of tim8. Chanel's mode selection switches on match. The stages are 0% 25% 50% 75%. When the phase is zero (sConfigOC.Pulse = 1-1), t...
I have experienced this issue on STM32L4R and STM32U5. If debugging through STOP mode (with DBGMCU_CR_DBG_STOP set), the flash memory occasionally seems to read out garbage as the MCU is coming out of STOP mode. This typically causes the CPU to har...
Hello,I have designed several custom boards based on STM32 MCUs, And are running fine problem is i have installed these across the country over 50 locations and now it very costly to go to each location for for required software updates or to debug i...
Hi,I am not able to get a correct reading from ADC1 INP0 (PA0). All the other analog channels works fine.The datasheet mentions this:ADC option register (ADC_OR), option bit 0 (OP0)For ADC1:0: INP0/INN1 GPIO switch control disabled1: INP0/INN1 GPIO s...
hello.After Mcu jump to app in custom bootloader, work while(1).Jump code is not working.
Hi!I'm working on a product that requires a very fast response time for capacitive touch sensing (in the order of <5ms). I'm currently looking into the TSC module in some STM32 controllers. However, I can't seem to find any information regarding the ...
I am working on a project where the end goal is that TIM8 is used to capture an incoming PWM signal on PC6. I want TIM2 to trigger from TIM8 and generate a single pulse on PB11. I have TIM8 working, capturing both rising and falling edges properly. ...
hi:I have two NUCLEO-H563ZI EVB boards and tried to implement I3C controller and target feature.When ENTDAA was issued, I obtained the target 48-bit provisioned ID "0x020813810100" from waveform, I saw the description from I3C register I3C_EPIDR ,i...
