I am programming Blue Pill stm32f103c8t6 mcu, and I am having troubles implementing I2C driver for it. I have tried one I2C example from one site, then tried to implement it on my own by datasheet, yet it does not work - it does not generate START.I ...
Hello,I have 2 piece stm32f407 board. i try to communicate them with I2C. One of them is master, other one slave. i tied 4.7k pull up resistors.when i feed slave board with usb cablo (debug cablo),master generates "start" condition and slave answers....
How to use the timer to keep our LED on 80% to 10% (linear down) of the time by setting a period of 500X, turning it on when the counter is 0 to 400X (0-15 minutes) and turning it off when it is 400X to 500X(5 minutes)?The time and period is a draft ...
My question here is this: Can the STM32G4x1 line access external flash memory (e.g., via QuadSPI)?My confusion is as follows: the following page:https://www.st.com/en/microcontrollers-microprocessors/stm32g4-series.htmlintroduces the STM32G4x1, G4x...
I've used stm32F103VC before, so this time I changed my MCU to stm32F103RC. I saw in the datasheet that the specifications of the two chips are almost equal.However, I cannot properly set the timer in stm32F103RC.Here's how I tested it:I make a clock...
I've picked up two discovery f3 board and configured to toggle a pin(in irq timer handler) everytime ARR=17999 on TIM2 with a clock of 36Mhz, derived from HSE crystal on board. If i connect the two pin to an oscilloscope i notice a drift between the ...
Posted on September 07, 2017 at 03:03HI,I'm currently test the STM32F429 Disco kit with some example on step by step.But I nerve that LCD always turn on, So Is there any way to turn off the lcd ? because I'm not ready to test the LCD.
I have an application where I'm using dual ADCs (let's say ADC 1 and 2) on an STM32G474.The desired regular channel sequence is:ADC1: channel 1, stop, channel 1, stopADC2: channel 2, stop, channel 2, stopThe ADC conversion is triggered by a timer. I ...
Im can not set SNSINC-bits from MACSSIR Sub-second Increment Register. Other Bits like SSINC I can set without problem ! (STM32H745XIH6U Discovery Kit ). Look like a Bug ?
Hello,I am working with an STM32F446RE, and oddly, I am able to get one pin to set HIGH using HAL and/or direct register manipulation, but if i try to use two or more pins the debugger console prints out "Device not responding" repeatedly before shut...
