Bad FW behavior on first debug session
Working on uvison5 keil IDEWhen I start the first debug session I don't get any interrupts (BLE).Only after pressing the "Rst" button, and jumping back to .s file the ISRs work.What am I doing wrong?
Resolved! How to do selective read from I2C EEPROM where write cycle followed by read cycle is required with no STOP condition in between?
I'm confused about how to set AUTOEND and other I2C parameters to execute the selective read illustrated in the attached timing diagram. I need to write the address to read from in write mode, then output another START condition right away, then I c...
mbed Nucleo64 F401RE: Binary file gets flashed but doesn't run
I have compiled some code on the mbed online compiler and copied the binary code onto the mbed Nucleo64 F401RE board. The LED on the ST_Link board starts blinking for a few seconds, and then the binary file disappears from the USB drive. I assume tha...
Resolved! How to write/read to/from EEPROM via I2C if the peripheral address is 7 bits + one eighth bit for R/W?
I have to write code to write/read to/from an ATMEL 24C256 EEPROM which has a 7-bit address and the eighth bit is for R/W. I guess the MCU should be configured for 7-bit addressing (ADD10 = 0) but in this case how does the MCU write the eighth (R/W)...
GPIO ERROR STM32MAT
Hi guys, i have this type of errors when i try to connect stm32f446re with simulink. I hope that someone can help me to fix the problem.
Read/Write to external EEPROM fails sometimes .What might be issue ?
Hi,I am using STM32L07XXXI am reading/writing and external eeprom using I2C" but I2C communication fails many time ". and system hangsDoes this function run needs to be atomic ?But using __disable_irq and __enable_irq effects HAL_GetTick() ?Can i ena...
Resolved! 255 as response to eeprom
Hi,I'm trying to write and read to/from M24512-R EEPROM.Seems that everything is fine writing and reading because HAL return is HAL_OK, but allways I've reading 255 value.My code:int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ ...
is it possible to receive unknown length uart/usart messages with mat/target uart receive block?
In mat/target uart receive block, the message length must be definite and the block waits until the input data length becomes equal to the defined length. if one or more bytes may loss in communication or the message length may be variable, so the bl...
