I'm working on an STM32L432KCU microcontroller. I want to develop two applications on the same MCU:An "OTA" app. This would load first. It uses a cellular modem to check for, and download firmware updates, and overwrite the existing application. Othe...
Hi,We are using STM32H750 for the new product development. The IDE is IAR Embedded Workbench and the RTOS is uC/OS-II.We found that it is OK to dereference NULL pointer on STM32H750. Any way to trap NULL pointer dereference to generate an access vio...
The CAN transceiver IC, i am using : TJA1057GT/3 , and I am seeing the some data waveform on oscilloscope but decoding is not happening. the baud rate varies for the CAN FD is from ~300kbps to 1Mbps(large fluctuation). Clock Divider : Divide kernel ...
I was struggling for a while to do a deep dissect of the cache behavior of my STM32F7508-DK device.Especially, when accessing SDRAM connected to FMC, the performance behavior was weird(some was much better than the others while the code looked semant...
I have some questions about how to start I2C on LL.Firstly, I rewrote the HAL code in LL and was a little surprisedWhy does it take so much code to read the data? virtual Status::statusType ReadByteArray(uint8* buffer, uint32 size) override { if (...
Hello all,Must use I/O expander (PCA9534PW) with STM32F334K8T6.Code:HAL_I2C_Mem_Write(&hi2c1, 0x20<<1, 0x03, I2C_MEMADD_SIZE_8BIT, 0x00, 1, 15000);All code (CubeMX generated): https://pastebin.com/GKNxHSut The usual HAL_I2C_Transmit is not suitable, ...
STM32F407VGTThe microcontroller is somehow goes under write protection mode while practicing firmware upgrade program.Is there any method to unlock write protection ?Cant able to program though keil. But ST LINK UTILITY software is able to reprogram ...
There is a very old machine that I want to remake.I cannot change the machine's sensors. The incremental encoder of one of the motors produces a jitter-like signal below at position 0. How can I determine this in reading with a timer. I am using STM3...
Hi all ,Am facing issue after 24 Hours of continious Run of Stm32f072RBT6 Controller for Change in reading of I2c BUS.Actually i have connected one Chip to Microcoontroller over I2C Bus . That Chip is Bq76930 (AFE).After24 Hours of Run, Controller s...
Hello, I currently have this code setup to erase a specific sector of the STM32F207 internal flash:static void eraseSector(uint32_t sector) { FLASH_EraseInitTypeDef eraseInitStruct = { 0 }; HAL_StatusTypeDef status = HAL_OK; if( HAL_FLA...
