Hello,I'm working on a low cost design which use LSI Clock. I need to compensate RC osc. deviation as best as possible.I didn't find technical datas about this. Is there any documents with precise datas on deviations according Temp. for examples and ...
I am running STM32L412 on 48MHz MSI, Timer 2 is configured in One-Pulse mode to output a 2ms Pulse. This is done by setting Timer 2 in PWM mode and with a prescaler of 47, ARR = 1999 and CCR = 1, Polarity=LOWAn interrupt is generated on update Event,...
Hi,I am learning how to use LPUART1 on the Nucleo-64 (STM32L433RCT6P) to generate messages on the COM4 port of my Windows 10 laptop. A "Hello World\r\n" message should be printed every time the blue User Button on the board gets pressed. Here are the...
1) Set output high2) When input is low wait till it is high3) When input is high read 6 characters4) When having read 6 characters then output low and return (or leave while loop)void Get_Instruction(){ HAL_GPIO_WritePin(GPIOA, GPIO_PIN_12, GPI...
I am using STM32F373RCT6 on customm board. By default systick timer is configured for 1ms but I want to configure for 1micro second. Is it possible? HCLK is 28Mhz and SYS clock is 28MHz.
Hello, I am trying to make my own bootloader for STM32H743AIIx. Unluckly, I can't erase or program flash memory by my code. I unlock both of banks and see LOCK in FLASH_CR goes down. I put PG to up and write data until EOP flag is set. Despite the fa...
I have a problem with DMA on this board that was not present on an F407 using code generated by Cube.I2S2 has been configured as master half duplex and IS23 as slave half duplex (fed clock and WS of I2S2). The plan was to have a MEMS microphone on th...
Hi,We were planning to use ST32H750VB (LQFP100 Package) in our design. The critical interface in our design will be SDRAM ( planning x16 bit).But while checking pin-multiplexing details for LQFP100 package, we observed that the D[0-15] and A[0-15] ar...
Hey there.. iam currently working with a L432KC on a custom made PCB.My programm reads a sensor value (I2C) and sends it so another device via SPI.This operation is performed every minute.iam using the HAL_Delay(60000) command to wait fot the next mi...
I had an issue with a STM32F103RB connected to a poor Power Supply with slow Ramp-Up.In this case, the CAN Peripheral was not correctly initialized. After adding an external Voltage supervisor the Issue dissapeared. My question: is it also possible t...
