Resolved! Tell NVIC not to exeucte a pending interrupt
I am using STM32F070 processor. I want to know a way of instructing the NVIC not to execute Timer interrupt in certain cases. Is there a way to do this? The situaltion is as follows-There are two interrupts- SPI and timer conifgured at same priority ...
Resolved! writing half word 16 bits on flash stm32f429ZI
Posted on May 23, 2018 at 10:05Hello evry body , i can write a byte on flash of stm32f429ZI WÄ°TH success . for info i use nucleo 144 and sector 23 the last sector .for example :with these adresses uint32_t locip1_adress=0x081E0001;//LAST sector for...
Flash Wear on STM32F030
I would like some clarification regarding Flash wear on an STM32F030. The datasheet states an "endurance" of 1000 cycles. Presumably this means 1000 write and erase cycles. If I erase a page, and then write to the page one 16-bit half word at a time,...
cannot send a message from a slave to a master i2c stm32f103!!
Posted on January 22, 2018 at 10:06hello trying to send a message from an stm32 slave to another stm32 master no success i2c protocol ,from master to slave no prblm i can do it very well ,i cheked many times the repository interrupt exemples and did...
Timer measuring time between state change on two digital inputs
I am using STM32F070 processor. I want to implement a function where I should measure the time difference between the change of input level on two digital IOs. There is no fixed sequence of the change in level on both the IOs. i.e. any one of the two...
Strange post?
https://community.st.com/s/question/0D50X0000AaXy4xSQC/code-processing-time-takes-too-long-im-using-stm32l476jgyxSeems one post has been "hidden"? (11 vs 12)
Code processing time takes too long. I'm using STM32L476JGYx.
I'm using SPI Communication in STM32L476JGYx. But the code processing time takes too long. [Sensor_IO_SPI_Read] function takes 2 micro sec. After that, I calculated the received raw data. But, it took more 30 micro sec. (32 micro sec)Below, the c...
reset stm32f412 fail
Hi friends . I have a new board developed with STM32F412Z 144 pins, I have a problem with Nreset of microcontroller . I tried to mount a simple reset circuit so as suggest by ST. a simple capacitors with pullup 4K7 and push button reset that c...
CAN is not functional after ACK error
We are using STM32L4A6VGTx MCU. In this for CAN we are receiving error multiple times (ACK error, EPV error, EWG error). Due to this we are not able to transmit and receive on CAN bus. Please let us know how to reset the errors, so that CAN will be f...
