Hello ,So for my project i need to send UART command every 15min Between this my MCU need to be sleeping And send a command if a Interrupt pin change stateBut when i wrote UART_transmit fonction in a ISR : RTC , timer , interrupt pin the comman...
Hi,I have been writing drivers for the ISM43341-M4G-L44-SPI WiFi module mounted on the STM32H7BI3-DK.I can send the device AT commands and get back the OK response, but after setting the network parameters SSID, password, security mode, DHCP after is...
Hi,I´m working with a STMF767zi and STMF429zi kits and I´d like detect ADC overrun. Sow I write the callbackup code:void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { flagOverRunCH1=0; if (hadc->Instance==hadc1.Instance){ // Overun detection/* ...
Hi everyone,I have synchronized the clock of 2 F7 nucleo boards with the same external oscillator. To do that I have activated MCO of a third nucleo board and then I have connected it to the Pin 29 of CN11 of 2 boards.2 Clocks of MCUs:I have used the...
Hello! I just got the STM32F429 Disco board and I'm trying to connect it to the HM-10 bluetooth module. I'm completely out of my depth here, I was hoping someone could nudge me in the right direction.I've worked with the HC-05 and the HM-10 on the ar...
I try process USART 1 upgrade over bluetooth module connected here.App setup all and jump to system memory, but here PA0 change and reset my here connected bluetooth. PA0 isnt defined in AN2606 .
Hi. I am using stm32l01c6tx. I want to use a very simple microsecond function. Libraries I have added below. "DWT" "CTRL" etc. when I included the libraries. It says not defined. But they are all in the "core_cm4.h" library. This library is in Driver...
In application note AN2834 (How to get the best ADC accuracy in STM32 microcontrollers), There is a clear error on Page 10, which defines 1 LSB by Vref+/2^12). But LSB depends on Resolution!If Resolution is 10, then it would be defined by Vref+/2^10....
