Hello. I was searching for information but I was unable to find clear answer. What is correct way to handle AT messages from gsm/bluetooth/gps modules ?I am making one product that will use at least two uart interfaces (SARA-R12) and NINA-W151 module...
Hi there,I am using the MCU STM32F103C8T6 and in my code I force an UsageFault condition but the UsageFault_Handler is not been called. I have enabled the USGFAULTENA bit in the SHCSR register, which enables the UsageFault. I envoked an UsageFault by...
Hi,I would like to use DMA request for USART1 RX and SPI1 RX. The AN4301 at section 4.3 states:Software sequence to enable DMAThe following software sequence applies when enabling DMA:Configure the suitable DMA stream.Enable the DMA stream used (set ...
But I can not return my message by CANLINE. When I do the same operations in STM32F103C8T6, I can get answers from the Canbus line.I chose the stm32f105RC family to use double canbus. I can't solve the problem. Do you have any ideas?. Thank you.
I am working on a STM32F746G-DISCO with I2C got on Arduino style board.I would like to reduce the I2C speed because sometime this lock my app with some external DAC chip.At this time I am using:CAMERA_IO_Init(); BSP_TS_Init(480, 272); and these...
I am developping a touch screen user interface to control an audio preampl and dac.I have no problems with I2C bus to set the registers of CT7302PL and ES9018K2M but if I try to read a single register the application hang.This is my I2C configuration...
currently i am using the stm32h743zi board.why pc8 and pc9 pins are not changed there transition state when they connected to 5v supply.
Hello,I am using stm32f4 discovery. I wrote 2 interrupts to blink LEDs in different speeds to write an example for NVIC. I have 1 question that I wonder about and 2 issues I couldn't solve. Here is the situation :All interrupts work well seperately. ...
Board: NUCLEO STM32F103RB - MB1136 C-01Hi all,I try read, trought ADC1_IN0 (pin PA0) , the temperauture value from LM35, but read wrong value.LM35: connected at 5V, GND and A0. ADC1_IN0: work at 8 MHz with voltage reference of 3.3V and 12 bit of reso...
I like to make a stand alone project from CORTEXM_SysTick. Is there any documentation how to do this? . Because if i change/copy anything Eclipse fails. Thanks.
