Hello, I'm working on a library for nucleo F401RE board, with LL library, I'm trying to add some embedded ARM assembly code as written in the guide of arm Developer web site:__asm return-type function-name(parameter-list) { // ARM/Thumb/Thumb-...
Hi all,I am facing a very weird issue with PWM on my STM32H723.I am generating a very fast PWM with TIM3 (TIMx_ARR = 10, TIMx_CCRx = 5, Timer Clk 275 MHz). However, the very first pulse is clearly way too long:Does anyone have an Idea where this come...
In one application I am currently developing I have a single pin for an adc input and an analog external mux(4051) on three pins that changes which of my actual 8 adc's is wired on this pin.I would like to iterate over the 8 different mux values and ...
Ahoy ST,1) I read a press release ( https://www.st.com/content/st_com/en/about/media-center/press-item.html/n3798.html ) that says there are Apple HomeKit solutions available, but I cannot find them. Where are they?2) NXP and Microchip advertise Appl...
I read the datasheet, a = device generation a, but I don't know what the difference is. Can you explain it in detail?
Dear ST Community,We have an old PCB with a ST10F269 chip on it.We would like to upgrade our PCB with a more recent STM32 chip.Could you please recommend us which chip of the STM32 family is compatible or closer to the old ST10F269? We want to apply ...
Hi,I currently have a STM32L4R9VI (that contains the DFSDM + DMA) and I am planning to sample an IF signal ( up to 10 MHz frequency) using an external Sigma Delta Modulator AMC1305M05 (20Msps - 20 MHz frequency - 16 bits resolution). I am not an expe...
HelloI can read mpu6050 via I2c1 in stm32F4Disco but I cant read mpu6050 in STM32F746 Touchgfx.All values returns 0.This is my reading code. it is working in 32F4DISCO:#define MPU6050_ADDR 0xD0 #define SMPLRT_DIV_REG 0x19 #define GYRO_CONFIG_REG...
Interfaced i2c_lcd with stm32f401re and try to program without any library .but getting junk data always,tried changing delay but same. void I2C_WriteData(uint32_t data){ uint8_t data1=0,data2=0,data3=0,data4=0; data1= data & 0x000000ff; data2= ...
