STM32L031G Custom Board - Program don't run after upload
Hello, I have a problem with a STM32L031G in a custom board. The program don't run after the program. BOOT0 is connected to gnd via 10K resistor. Attached you can find a circuit diagram and clock configuration. what could be the problem? Thanks Mich...
STM32H7B0 incorrect ADC sample rate
Hey,We using an STM32H7B0 100 pins MCU.With this mcu we will sampling 1 16 bit ADC input at 1 MHz and we using a DMA in circular mode for 1000 samplesThe ADC clock works at 48Mhz, the clock precaler for the ADC is divided by 32 and the sample time is...
STM32F4xx TIMER1 ETR
Hello, I am struggling to get the TIM1 of a STM32F411 to be triggered by an external GPIO. What I want to achieve is having ETR1 (PA12) to trigger TIM1 and have 4 repetition of 199 periodI am using STCubeMX and I must do something wrong as it is not ...

External loader in release-build is not parsing at start-up in CubeProgrammer
Hi!The DEBUG build version of my custom loader is working but is slow, so I tried RELEASE build instead to hopefully get a smaller bin-file with a faster and more efficient execution.However, CubeProgrammer fails at startup with a “loading-file-error...
Resolved! STM32 ROM bootloader, initial state and when erased
Hi,On the STM32 F4 products, there is a hardware/ROM bootloader, that can be activated through the BOOT0 pin. It works great, no issues with that.In a production environment, I would like to flash the board automatically, without manually pressing bu...
Tacq STM32G0x0
Hi. We are using STM32G0x0 family in our project. We are running ADC clock at 30MHz. The sampling time is 7.5 cycles, we configure the ADC to trigger every 500uS so Trigger Frequency = 2kHz and the resolution is 10bits. I know the Tconv = Tsampling...
