Hi, I would like to know method and sample code storing data without erasing whole memory page. I do refer example FLASH_EraseProgram, but i have wrote program that almost finish up the flash memory, if i erase a page, a 2KB page, it will erase my co...
Hi guys,I could set MCU into bootloader mode manually by using PH3/Boot0, but I can't get trigger bootloader via SW... I did check previous posts, but somehow it does not help.HW setup: I have dev board with STM32L431. It has USART1 (PA9, PA10) conne...
HiI would like to debug STM32F303RDT6 using a combination of Keil and ULINK2.When I start debugging on the target microcontroller (STM32F303RDT6), **Not a genuine ST Device! Abort connection** is output as shown below.We investigated the cause.I foun...
Getting this error and have no idea how to troubleshoot it further:Break at address "0x800c44e" with no debug information available, or outside of program code.<signal handler called>() at 0xfffffff1Break at address "0x8004bf4" with no debug informat...
Hello,I'm currently sending AT commands to the Grove LoRa E5 module from Seed Studio, when I send commands like "AT," there is no response from the module. I've connected the module to the USART of the STM32L476RG board. If anyone has encountered and...
AN4073 states that ADCxDC2 can be used only if ADC frequency is at least 30 MHz. I used it by mistake with ADC frequency 22.5 MHz. It seemed like it improved the precision by about 5 LSBs. The software worked just fine: no crashes, no funny misbehavi...
The MCU used is STM32F103VET6. I want to use TIM3_CH1 (generating a PWM signal of 10kHz, 30% duty cycle) as the master input of TIM4_CH1. The TIM3 acts as the prescalar of TIM4 and thus making TIM4 to ouput a PWM signal of 200Hz and 60% duty cycle. T...
Trying to configure my project to use USART2. When I opened "System Core" and "Connectivity", I see that a bunch of options are disabled or have warning signs. I haven't been able to find out why or how to change them, and this isn't an issue I have ...
