Dear SIR,What is the max number of external inputs using interrupt at the same time?In my application, it uses 22 GPIO as external input as Fig.1.1. I use STM32CubeMx to set "PB1" to "GPIO_EXT1" then set "PC1" to "GPIO_EXT1", after setting "PC1", the...
Any Core Hardware Register available to user which is not used by HAL or the Processor itself which I can safely use without disturbing the rest of the MCU?I am using an STM32L431. To keep the System State in check I am using a Volatile uint32_t vari...
One of the practices of software design is to use volatile buffers when ISR and main loop access the data in the same buffers. This makes sure certain compiler register optimisations do not create unreliable code.If I look at the HAL code for the USA...
Hello,I would like to program the STM32 to control the circuit SAA1064 by I2C, using the STM32cubeIDE and HAL functions (HAL_I2C_Mem_Write,HAL_I2C_Master_Transmit, HAL_I2C_IsDeviceReady). then with the function "HAL_I2C_IsDeviceReady" shows that : th...
Hi all, i'm experimenting using ADC in STM32H743ZI2i managed to get the single channels working on ADC1 and ADC2,and i want to use ADC3 with multiple channels, oncourse i followed all the manuals in youtube etc.. but still no lucki am using ADC3 cha...
Hi everyone,ı was trying to make adc to dac using DMA. Shortly the adc value is writed into DAC data register. So that the potentiometer is turned then the digital value is writed ADC register. The brightness of led is changed. However, ı get ADC val...
Hi,We are referring to the bill of materials of the STM32F412G_DISCO board. We are looking up for QSPI flash IC (MICRON N25Q128A13EF840F) used in the development board for our new design and found that its lifecycle is obsolete on mouser india. Also ...
Ok here is the situationDid a board design, when plugged in i noticed 3.3v was not outputting correctly. Realized I put the wrong 3.3v regulator, maxes out at 100ma. Removed and put in a 3.3v regulator that goes up to 800ma which i thought would be f...
Hey guys,I set the SWD up for a project inculding a PCB with an F411CEU6 and an VL43L8CX. To test the pcb, I wana get the distance printed to the SWD console. I set up the SWD and with the main.c file it works fine, but with the vl53l8cx.c the printf...
I have had a couple of Nucleo 144 test/demo boards for a couple of years and have had no issues with them. So I decided to try and create the simplest PCB from scratch. What is happening is the chip itself is resetting when powered with a repeated si...
