Hi everybody,i am currently working with the STM32H755ZI (Revision V) on a NUCLEO-144 Board and I need to use all three ADCs. To use these ADCs I need to calibrate them according to the reference manuals and the application notes. Calibrating the off...
halo!i have a adc_value as array and i hava this for potentiometer, i want to call the adc_value as int, but i can't thingking for this now, can anyone help me?
Can I know what is difference between internal adc of STM32f429 disc1 board and an external 12bit 1MSPS adc.Which adc to use for any application that needs more accuracy whether I should go for external or internal adc.Will internal adc produces any ...
Hello,I work in a company that uses stm32F031C4T6 and we manufacture 40,000 cards a year with this reference. I was wondering if it would be possible to ask the manufacturer to program the microcontrollers directly in their factories, because for our...
Hi everyone, I have a STM32F042F6P6 chip. I want to read 9 analog channels on it.I guess there are at least 2 options: configure a scan mode with DMA, and staying in polling mode.I decided to stay in polling mode to avoid a potential problem due to D...
Hi All,I am working at project with STM32H7 and NetX Duo. At current version of Ethernet driver from ST (X-CUBE-AZRTOS-H7 v3.0.0) is not handled by any way state when link is disconnected. Link status variable nx_interface_link_up is set at "Enable L...
I'm trying to set up a DMA transfer from UART1 periheral to memory. Using LL drivers. Using STM32Cube for "convenient" setup. It puts the all the USART peripheral init in usart.c. Where for GPDMA it does something like: /* GPDMA1_REQUEST_USART1_R...
We are using STM32H723ZG on custom board. Sometimes, we want to jump to System Bootloader (address 0x1FF09800) from our application. Then we connect to device via USB DFU. I thought that it works reliably, however we discovered that sometimes, there ...
Hi,I want to make PWM stream with various duty, so I'm testing PWM with DMA using NUCLEO-G0B1RE and HAL library.The first image shows weird pulse train. I set DMA buffer with [duty 1] * 8 + [duty 17] * 8 + [duty 5] * 8, but oscilloscope captures eigh...
Hello,I am trying to do an OTA upgrade on my STM32H750. I am using QSPI flash in dual mode as the IC does not have so much internal flash for my application. My application is running FreeRTOS and does have a LCD screen. So I build a bootloader to co...
