Resolved! Hi team! I am working on the OLED interfacing with STM32F103C8T6. All I want to do that is to display the counter value from 0 to 255 on OLED. But when I simply put the random number such as 48 it shows its equivalent ASCII value not a decimal value.

What are the possible reasons for exception MUNSKERR in STM32F4 while debugging?

Hi,I am using Stm32F4Discovery board.While debugging my customised application I got trapped in MemManage_Handler exception and when I viewed the cause for that exception in CFSR register at address 0xe000ed28, the bit MUNSTKERR was set. When referre...

BLE connection terminates after discovery of primary service using X-Nucleo-BNRG2A1

I am using the X-Nucleo-BNRG2A1 with a Nucleo L476RG. I have loaded the sample application called Central Device from the X-CUBE_BLE2 Rev 3.30 pack. This application is already configured for the two boards previously mentioned. The code builds and l...

STM32L082 (CMWX1ZZABZ-078) hardfaults while running HAL's CRYP_ProcessData()

I've been trying to cypher a plain text using HAL_CRYP_AESECB_Encrypt(), but everytime I call this function, it gets stuck in a while loop inside CRYP_ProcessData().Here's a screenshot of the exact code snippet where everything get's ruined:The fact ...

What is the difference between STM32F405ZGT6 and STM32F405ZGT6W (STM32F405ZGT6J, STM32F405ZGT6V)?

According to the datasheet the devices with letter suffix is preprogrammed, but not explained how and in what purpose. Is it safe to solder it to directly to PCB without erasing it previously? Thanks.

Hello,is there a method to read/ write NOR flash on QSPI

Reg: STM32F767 Simulator

Hi I am using STM32F767 series for development purpose. Is there any simulator to test the code without device. Highly appreciate if you can share the link or tool that will be great help for my development.Thanks,Jagannath

STM32H743 - DMA + DAC - How to program ?

dear ST,I'm trying to program the STM32H743 to use DMA control of its DAC - my understanding is this involves use of a Timer also. 'Circular' mode would be relevant meaning the file being output (just a sine wave for now) is continually replayed. Me...

source code of STDES-3KWTLCP

Hello, we are developing a produce of AC-DC converter based on STM32。 Can you offer the source codes (PFC and LLC) of STDES-3KWTLCP. Thank you very much

A solution to resolve and exit from the BusFault triggered by am Flash memory double-fault ECC

I have spent a bit of time looking for a solution on how-to deal with BusFault caused by a flash-read ECC event. This is what I would like to share with others in the absence of finding an online solution myself.void fv_flash_eec_test(void){ volati...
