Resolved! Can the difference between stm32l152c8t6 and stm32l152c8t6a be shared?
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= ...
Hi i am unable to see SCL,SDA signals in logic analyser. Connected Pullup resistors to Scl,Sda pins. Interfaced with PCF8574 IC (I/O Expander) ,Hardware Connections are fine but i am not getting even clock(scl) in STM32F401RE#include<main.h>#include<...
While I was looking for H7 DMA data,I saw the article below that DMA is not working on the H7 device.https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesSolution 1 from that article is shown below.--------------------------...

Hi All,To get around a problem I was having with timer capture using DMA (another topic) I changed my timer code to use interrupts. The seems to work when I debug step through it but not when I run. I am using TIM8 in input capture mode for CH1 and C...
The STM32H743 datasheet says nothing about clocking the timers. Reference manual has a chapter dedicated to each timer's counter clocking. For each type of timer the only clock is so called "Internal Clock" CK_INT . What is it? Opened my project's Cu...
