Voltage offset is introduced for 32MHz clock on STM32L4S7ZIT

2022-04-14
Hi, Im working on STM32L4 chip. I wanted to work on LTDC with 32MHz clock. I'm using internal 16MHz clock and generating 32MHz using PLL. When I give output of this clock pin to PA8 MCO pin, Im able to see 32MHz triangle wave with ~1.2V offset. When...

2021-11-11
Hi,I'm working with STM32F746G DISCO board. I have 4 different image arrays- img1[65536], img2[65536], img3[65536], img4[65536]. I would like to display this on the screen simultaneously one below the other.In the below program,int i=0;   while(i<4) ...

Hi, Im using ST25DV04 with ESP32. Im unable to write tags onto NFC. I2C Communication fails.

2021-08-18
During initialization of CC, as I understand we should have values 0xe1,0x40,0x40,0x00But I am getting 0xe1,0x40,0x40,0x43. Im trying to manually write 0xe1,0x40,0x40,0x00 at address 0xa6, 0x00 which is failing. I ignored that and tried to write a te...

UART Receive on STM32F746G only when data is sent from master board

2021-06-10
I'm communicating between STM32F746G-Discovery ans ESP32 using UART (PC6 and PC7 pins on STM). ESP receives some data at certain intervals over WiFi and transmits it to STM via UART. On STM I want UART to receive data only when ESP32 has transmitted....
