J-Trace Pro connect and download error with STM32L552E-EV board
Hello,I’m learning embedded development with a J-Trace Pro and an STM32L552E-EV board. After downloading the trace demo project from the segger wiki, I try to debug it with Segger Embedded Studio and Ozone.Here is the board information.https://www.st...
Receive data from multiple Serial ports as Interrupt STM32F103RE
Hi, i need to receive serial data as ISR. i have 3 USART module. this is my test code. this is work fine. but some time suddenly stop the firing ISR routing of receiving event .when i call this line after stop the modem RX ISR function HAL_UART_Recei...
Printf no redirect
Hello, in my project I'd like to use printf for print debug messages, but if write printf("Test"), I don't see the string on the UART.I have redirect printf:#ifdef __GNUC__ /* With GCC, small printf (option LD Linker->Libraries->Small printf set to ...
Trouble setting I2C device registers
I am using an STM32L476 to run an MMC5983MA magnetometer and a LIS2HH12 accelerometer, using I2C. The devices are initialised using the STM cube generated code, then the registers are set, and then checked. When I check the accelerometer registers, ...
STM32L4+: RTC Calib Out (PB2) and RTC Timestamp Input (PC13) at the same time?
Hello everybody,i have a problem with the RTC Calib Out (1Hz) on PB2 and TimeStamp Input PC13 (Board: NUCLEO-L4R5ZI).PPS (1 Hz clock) should be on PB2 (RTC_Calib_Out) for time synchronization with other chips.PC13 should be configured as TimeStamp In...
STM32L432KC with W25Q16JV
Hello Team,I want to use STM32L432KC with W25Q16. I have generated the code through CubeMx. I have tried to ready ID from W25Q16, and I getting 0xFF. When i have tried with the Arduino UNO board, it is working perfectly. /* SPI1 parameter configurati...
Resolved! Acordding to official Datasheet,we know STM32H750 have only high-speed memory of 128 kBytes,but at some communities someone use it token for 2M kBytes. why?
At some communities, some people can use STM32H750 token for 2M kBytes. why? for ecample ARMFLAY's H7-TOOL production ,it's amount of code is much larger than 128 kBytes. could we do copy this ?
RS485 collision detect on stm32f103 of SAE J1708 / J1587
HiI'm trying to implement SAE J1708 / J1587 on stm32f103CB, however I couldn't find how to detect collision occurred, the article ( https://www.kvaser.com/about-can/can-standards/j1708/ ) only mentioned both sending nodes have to release control of...
