Hi guys, I have some Arm microcontrollers (STM's to be specific). There's a tutorial on youtube(Link to it-https://www.youtube.com/watch?v=R6SstBoXjKc&list=PL6PplMTH29SHgRPDufZhfMRoFwRAIrzOp&index=1 If you look at more videos in the playlist, you'll...
I am working with STM32H743, and I want to use Pin no. 89 as DAC output. Is there any register setting where I can change PA4 to PG4(89).I tried replacing PA4 to PG4 in a working example code, but the output still comes on PA4.
I've been reading the STM32F427 and I can't confirm my understanding - so I'd like to ask.I have data that I must push out a GPIO faster then should be serviced by an interrupt.My intent is to use TIM1 - set a period - then set 3 output compares havi...
Hi guys, I am planning to buy a bare STM32 ARM Microcontroller and wanted to know wether it comes with a boot loader so that I can directly upload code using Keil u vision, STM32 Cube MX and a ST link V2. If there is no boot loader shipped with the u...
Dear experts, can you please give a suggestion about how to proceed with the following problem?I am trying to display the information on the PCD8544-driven LCD (aka Nokia 5110) about the incoming UART messages.I am using STM32CubeMX to configure the ...
Posted on February 23, 2018 at 18:10Dear All,I use SPI as a master with 2 lines full duplex with DMA on STM32F303RE with 8-bit data size.Frames are made of variable number of Bytes. Normally SPI clocks out 3 Bytes of command on MOSI line + 4 Bytes o...
Hello AllI have configured ADC1 and ADC2, each with CONT=1 and L = 0, to convert two respective analog inputs on a software start, and the scheme works fine. However, when in the CCR I set the MULTI bits to 0b00110 (or to anything else for that matte...
Hello!In my design, I want to use the STM32L100 series microcontroller. How can I get a clock frequency RTC of 1 Hz if I use a highly stable external oscillator with a frequency of 30 MHz to clock the microcontroller.PREDIV_A can be 1,2,3, ..., or 12...
