Measuring pulse durations with microsecond precision or better

Problem I'll be receiving pulses and want to know the relative times of pulse start/end with microsecond precision (or better). Pulse characteristics: pulse frequency: probably 1Hz to 10Hz pulse length: 1μs to 200ms pulse spacing: >10μs between…

Using multiple ADC-s with DMA simultaneously – STM32

Is there a way to use DMA with multiple ADCs at the same time? I know you can scan multiple channels on one ADC, but I currently use 5 different ADCs on my STM32G4. I use the HAL library function HAL_ADC_Start_DMA(). Do I have to stop the DMA…

Is it feasible to use both MCU UARTs if it only has two?

I love STM32 nucleo boards and they have tons of UARTs. Now want to use two UARTS for protocol conversion (rx at 115200baud, tx at 38400) on a stm32g0316 discovery board that has only two UARTs. How would I be able to connect the debugger (ST Link)…

DMA Continuous Request functionality

What is the difference between these features on STM32G0 "Scan Conversion mode" and "Continuous conversion mode" and "DMA continuous request" features? When you go on CubeIDE you will see these features on ADC configuration.

The microcontroller (STM32G0 Series) does not work after seting FLASH read protection

I am using STM32G030F6P6 microcontroller. I tried to make flash read protection: if ((FLASH->OPTR & FLASH_OPTR_RDP) != 0xbb) { FLASH->KEYR = 0x45670123; FLASH->KEYR = 0xCDEF89AB; while (FLASH->SR & FLASH_SR_BSY1); FLASH->OPTKEYR =…

Is it okay to split the same net to sample an analog signal in two ADCs?

I have an analog signal that comes from another place with a range of 0-1 V, the required resolution should be 10 bit. I want to sample the same signal in two ADCs, the internal ADC of the STM32, and an external ADC (AD7606BSTZ). Is it worth adding…

Is this an example of STM32G0 core lockup during software reset?

Using a STM32G0F06 I have a bootloader/application that I am debugging. I am facing a strange problem. Often, I command the app to drop to bootloader (via a software reset). When I execute the software reset code, occasionally the core locks…

STM32G030: more smaller and simpler library for software development than HAL/LL/libopencm3/tinygo?

I'm quite a fan of the STM32G030x6/x8 "line" since it is small and fits most of (my) needs as a more modern replacement to the Arduino platform built around the 8-bit Atmel/Microchip micros. However when it comes to developing software for it, I'm…

Quantify STM32G4 slow vs fast ADC channels

The STM32 G4 reference manual mentions a concept of slow and fast ADC channel. Quoting from the ADC section of the manual: Number of external analog input channels per ADC – Up to 5 fast channels from GPIO pads – Up to 13 slow channels from GPIO…

1V on ADC pin with DMA continuous requests

I have a STM32G071 Nucleo Board and also the IC itself. In CubeIDE, I set a pin as ADC and activate DMA and enable the DMA continuous request in the ADC settings. After executing the code and starting ADC, there is always 1 V on this pin no matter…
